What is an Outdoor Chiller?

An outdoor chiller is a type of machine designed to remove heat through the process of vapor compression and absorption.

A liquid refrigerant circulates across the machine, particularly through the heat exchanger to generate cold air.

Its process will normally create heat as its by-product, which means the system has to exhaust the heat to achieve a higher efficiency operation.

 

Outdoor Chillers

What are the Main Components of an Outdoor Chiller?

The main components of an outdoor chiller are the condenser, compressor, and evaporator.

The condenser unit changes gas into a liquid form. It is where the refrigerant passes through to transform into liquid form.

The compressor draws vapor to compress it, causing the temperature to rise.

The evaporator’s job is to transform the liquid refrigerant back into gas to restart the process.

What is the Working Principle of an Outdoor Chiller?

Outdoor chillers follow the vapor absorption or compression principle.

The idea is to allow for the continuous flow of the refrigerant into the water chiller system.

As the system pumps the refrigerant through, heat extraction occurs.

Outdoor Air Cooler

How Does an Outdoor Chiller Work?

Manufacturers design outdoor chillers to get the coolant flowing through the system at the desired temperature.

The idea is to extract heat out of the area consistently and continuously.

The refrigerant transforms into a liquid or gas form to facilitate the process.

Which Gases Do an Outdoor Chiller Use?

There are different refrigerants used in an outdoor chiller, but the two most common ones are Ammonia and hydrofluorocarbon.

Ammonia is a halogen-free gas with the highest rating for heat absorption.

On the other hand, hydrofluorocarbon, or simply HFC, is commonly used in centrifugal chillers.

What are the Types of an Outdoor Chiller?

There are at least two types of outdoor chillers and these are the single-zone and dual-zone water chillers.

Single zone chillers have only one refrigerant zone while dual zones have two of them.

It also follows that they have single and multiple circulation pumps, respectively.

How Do You Lower the Entering Water Temperature of an Outdoor Chiller?

There are different ways to lower the entering water temperature of an outdoor chiller and an experienced HVAC technician will recommend the best method for your device.

Some would suggest reducing the chilled water set point, however, this method may not work for every unit.

Work closely with a trusted expert when doing this.

What are the Safety Devices Installed in an Outdoor Air Cooler?

There are at least four safety devices installed in an outdoor chiller, and these are pressure protection, flow direction control, compressor protection, and pump protection.

There’s almost always a valve to activate these safety features although in most cases, they automatically activate when the sensors detect any fault in the system.

Indoor Air Cooled Chiller

What is the use of the Antifreeze Alarm in an Outdoor Chiller?

Manufacturers install an antifreeze alarm in an outdoor chiller to protect the evaporator.

Glycol is the antifreeze used in these cases and its job is to prevent evaporator splitting.

Why is Glycol Used in an Outdoor Chiller?

Manufacturers use glycol in outdoor chillers because it reduces the refrigerant’s freezing point.

Reducing the freezing point ensures the continuous flow of refrigerant while also preventing scaling and corrosion.

Glycol also helps in preventing bacterial and algal growth inside the system.

Chiller Package

How Long Does an Outdoor Chiller Last?

A well-maintained outdoor chiller package may last up to 20 years or even more.

The key is preventive maintenance as it will assure users that their chillers will last for at least 15 years.

Why is it Important to Keep an Operating Log on an Outdoor Chiller?

Keeping a log is the first step to maintaining a chiller package.

This practice is important in ensuring that your equipment runs efficiently and smoothly.

As the outdoor chiller ages, it will gradually develop issues. Observing these issues becomes easier if one keeps a maintenance log.

What Causes Low Evaporator Pressure on an Outdoor Chiller?

Outdoor chillers get low evaporator pressure when the refrigerant runs low.

Once this happens, then the whole system experiences decreased pressure.

At this condition, the outdoor chiller will not function optimally or efficiently.

Does an Outdoor Chiller Need a Cooling Tower?

Not all outdoor chillers require a cooling tower but the ones that have it tend to function a lot better.

Cooling towers act as giant heat exchangers, blowing ambient air to help remove heat and take it outside.

You can find these towers install on the roof of buildings.

How Do You Clean an Outdoor Chiller?

HVAC technicians are usually the ones to clean an outdoor chiller.

They start by valving off the chiller and draining the condenser and evaporator.

Then they remove all heads and covers so they can brush clean the condenser and evaporator tubes, including gasket surfaces.

How Do You Check for an Outdoor Chiller Leak?

HVAC technicians check for chiller leaks by following the tube leak checking procedure.

First, they remove the heads, shut off the water supply, and drain whatever water was left in the system. Then they close the valves.

Lastly, they pressurize the shell with nitrogen to see if there are any tubes leaking.

What Do High Purge Counts Indicate on an Outdoor Chiller?

Excessive purge run times may mean that there is a leak in the chiller’s refrigeration system.

If there are no leaks in the chiller, then the unit will indicate no purge run time at all, and it may remain that way for months.

Why Do Outdoor Chillers Need Purge Units?

Purge units in outdoor chillers are necessary to prevent extensive damage caused by leaks.

The purpose of these units is to contain the refrigerant that has leaked out of the system.

Where are Outdoor Chillers Commonly Used?

Outdoor chillers are common in areas and facilities where there are high cooling requirements.

They have seen many uses in processes such as tool and die-cutting and injection molding.

They are widely used in factories producing food and beverages, lasers, chemicals, semi-conductors, and machine tools as well.

What Do Outdoor Chillers Do in a Commercial Building?

The major components of an outdoor chiller are the condenser, evaporator, compressor and expansion valve.

Other equally important parts include the control unit, water box, and power panel.

For the outdoor chiller to work seamlessly, all of these parts have to be fully functional.

How Does an Outdoor chiller Work?

An outdoor chiller circulates the refrigerant gas through the heat exchanger to cool the area or the air around it.

It distributes chilled water to the coils and recirculate it back to the system and restart the process.

The purpose of the coils is to transfer heat from the air to the chilled water to cool it.

What is the Working Principle of an Outdoor chiller?

Since most outdoor chillers are air-cooled chillers, they work by directly cooling external air through a mechanical circulation process.

However, they are some water-cooled chillers used in an outdoor setting as well. They use mists of water instead of air to begin the cooling process.

Outdoor chillers don’t normally require a cooling tower, unlike indoor chillers.

What is the Function of an Outdoor chiller?

The function of an outdoor chiller is to ensure that there is a continuous flow of coolant to maintain the desired temperature within the space or system.

If the outdoor chiller is working optimally, then it effectively extracts heat away from the area.

In many industries, outdoor chillers help in many manufacturing plants. In commercial and residential areas, their main function is to cool the building.

What is the Difference Between an HVAC System and an Outdoor chiller?

An outdoor chiller is generally a part of a huge complex of HVAC chiller systems.

HVAC stands for heating, ventilation, and air conditioning.

It is a system that works 24/7 to maintain the desired temperature in a residential, commercial, or industrial setting.

What is the Difference between an AC and an Outdoor chiller?

An AC or an chiller air conditioner system dehumidifies spaces and removes heat from the area following the basic principles of refrigeration.

Outdoor chillers are slightly more complicated.

The refrigeration cycle used by outdoor chillers follows the vapor compression and absorption method.

What is the Difference between an AHU and an Outdoor chiller?

AHU stands for Air Handling Units which task is to circulate and condition the air around it.

An AHU normally has heating and cooling elements, blowers, filter racks, chambers, dampers, and sound attenuators.

Their main purpose is to distribute the already cooled or conditioned air throughout the building.

How Many Types of Outdoor chillers are There?

There are at least three types of outdoor chillers and these are the air chillers, water chillers, and evaporative condensed chillers.

Air chillers and water chillers work almost the same way with their only difference being their respective condensing sources, which is air and water.

Evaporative condensed chillers, on the other hand, are the alternative to the first two types of chillers. They function by constantly working the condenser and evaporator to reject heat and cool the atmosphere.

Which Type of Outdoor chiller is Best?

The right type of outdoor chiller to use will depend on its application.

There are outdoor chiller units designed for industrial, commercial, and residential applications.

If you need an efficient and quiet outdoor chiller, then a water-cooled chiller is best. Air-cooled chillers, on the other hand, are best for users working on limited spaces.

Which Compressor is Best for an Outdoor chiller?

There are different compressors for use with outdoor water chillers, such as reciprocating, scroll, crew, and centrifugal compressors.

Centrifugal chillers are among the most cost-effective options, which is why many outdoor chillers have them.

Centrifugal chillers are also more cost-effective for larger loads.

What is the Function of Compressor in an Outdoor chiller?

The task of compressors is to circulate the refrigerant gas within the system while concentrating the heat produced.

The compressor is also where the pressure of the gas changes from low to high.

Needless to say, the compressor is the heart of an outdoor chiller.

How Do You Start an Outdoor chiller?

To start an outdoor chiller, remove first the shut-down tag.

Be sure that the load is light and that the condenser and chilled water valves are at the right operating positions.

When these checks out, then you can start filling the heat exchanger and if present, the cooling tower.

How Do You Control the Noise of an Outdoor chiller?

If there’s a need to control the noise of an outdoor water chiller, the most common solutions used are acoustic blankets, sound curtain walls, and steel barrier walls.

Acoustic blankets are cheap, effective, and easy to install.

The two other options entail the installation of walls or barriers that may require construction or modular work.

What is the Delta-T Concept in an Outdoor chiller?

Delta-T refers to the drop in the chilled water temperature as it passes through the evaporator.

Generally speaking, it is a function of the chilled water flow rate and cooling load.

When cooling, the ideal range for Delta-T is between 16- and 22-degrees Fahrenheit or negative 5- to 9-degrees Celsius.

What Does LWT Mean in Outdoor chillers?

LWT stands for Leaving Water Temperature while EWT means Entering Water Temperature.

Users must monitor the entering water temperature and leaving water temperature of their chillers.

The ideal entering water temperature is at 45 degrees Fahrenheit or 7 degrees Celsius.

If the difference between the EWT and LWT is less than 10 degrees Fahrenheit, then it signifies decreased efficiency level.

What is Chiller Approach?

The chiller approach or condenser approach is the difference in the condenser’s refrigerant temperature and water temperature.

If the chiller approach value is rather high, then it means reduced heat transfer, higher energy consumption, and decreased in cooling capacity.

How Do You Determine the Chiller Approach?

To calculate the chiller approach, get the temperature of the refrigerant on the lower side of the heat exchanger.

Next, get the cooling water’s temperature as it leaves the condenser.

The difference in the value is called the chiller approach, and you want to keep its value low.

What is Chiller Setpoint?

The chiller setpoint is the temperature that an outdoor chiller works optimally.

Typically, that value is at 50 degrees Fahrenheit or higher.

A lower setpoint may require extra user attention as freezing and other damages may occur.

How Do You Know the Capacity of an Outdoor Chiller?

To compute the capacity of an outdoor chiller, divide its BTUs per hour by 12,000.

The result is the chiller capacity, which is the value that it requires to handle heat load in tons per hour.

What is Chiller Staging?

An outdoor chiller has to follow a staging down the process to keep it functioning at an acceptable working condition.

Outdoor chiller staging helps in avoiding power surge, poor performance, and low flow rate.

To stage your outdoor chiller, simply wait for a few minutes after it fails to meet its designated setpoint.

What is Chiller Management System?

A chiller management system is a software running on a microprocessor-based controller integrated into chillers.

Users may view it output data over a network or computer station.

This management system of an outdoor chiller allows users to control the device based on its optimization and design.

Do Outdoor chillers Use Water?

There are outdoor chillers that use water as its source.

However, not all chillers do. In fact, many outdoor chillers don’t require the use of cooling towers.

A majority of outdoor chillers use air as its source.

Why are Outdoor chillers Used?

Commercial and residential areas install an outdoor chiller to serve as the building’s centralized air conditioning system.

It is also a better choice for people who want a more efficient and affordable alternative to traditional space or surface cooling.

An outdoor chiller is also very flexible, which means users may customize them to serve many other uses and applications.

Is an Outdoor chiller Safe?

An outdoor chiller is perfectly safe to use, especially if it is manufactured by Geson.

There are several safety controls installed in the unit and their function is to protect the system from damage arising from low refrigerant temperature, high condensing pressure, low oil pressure, and other issues.

These safety features also ensure the safety of the users and the occupants of the building.

How Often Should Chiller Tubes be Cleaned?

Outdoor chiller maintenance experts recommend cleaning the evaporator tubes of an outdoor chiller once every three years.

The condenser tubes, on the other hand, require yearly cleaning.

Experts also recommend a periodic check of all major components of the outdoor chiller.

How Do You Clean the Coils of an Outdoor chiller?

Hire an HVAC technician to clean the coils of your outdoor chiller.

If you have to do it yourself, be sure that that system is fully shut down before trying anything.

You’ll also need an adequate supply of water, some coil-cleaning solution, and a power washer that is compatible with your system.

How Much Energy Does an Outdoor chiller Use?

When used in the ideal part-load condition, variable speed chillers may consume between 0.19 and 0.32 kW/ton of power.

To ensure that your outdoor chiller is working optimally, make sure that its efficiency level remains in check.

Low COP or Coefficient of Performance means that the industrial water chiller system uses lower electrical energy to produce the desired cooling effect.

How Can You Reduce the Energy Consumption of an Outdoor chiller?

To reduce the energy consumption of your outdoor chiller, screw chiller or scroll chiller,  simply adjust the condenser water temperature control.

Lowering the outdoor wet-bulb temperature leads to huge savings in your energy bill.

On average, a temperature reduction of 5 degrees Fahrenheit will generate 2.5% savings on your power bill.

Why is the Outdoor chiller Not Cold?

If your outdoor chiller is not cold, then there might be something wrong with it.

Call an HVAC technician to help you out but the most probable cause is blocked or dirty air condensers.

If that’s not the issue, then the problem may lie with the refrigerant or compressor. The technician will say if they need replacing.

How Do You Troubleshoot an Outdoor chiller?
