The most general refrigerant gases used for air cooled chillers over the years include:
Chlorofluorocarbons (CFCs), including R12.
Hence, this is known to assist to the greenhouse gas effect.
What is the difference between HVAC and chiller?
The key difference between HVAC and chiller is that the former is a system of equipment that moves air in buildings while the latter is a device for cooling things.
HVAC includes air handlers, furnaces, fans, pumps, boilers, coolant coils in order to provide heating and cooling to buildings.
Chiller works by pumping refrigerant through refrigeration coils that are cooled with water or some other coolant.
This results in the production of cold water or gas which can then be used for various purposes including heating buildings with radiant chillers.
HVAC systems are used in most commercial structures while chillers are more commonly found in food production facilities and greenhouses.
What is the use of chiller in HVAC system?
The chiller is the “refrigeration source” and “heart” of the central air conditioning. The circulating water to each room is “internally exchanged” by the chiller, and the temperature is reduced to “cooling water”.
A chiller is usually used in places like shopping malls or schools that require a lot of cooling for an extended period of time.·
Is HVAC Chiller systems important in everyday life?

· How does ambient temperature transfer in an HVAC Chiller?
It operates by transferring thermal energy from one mean to another through coils in the system.
However, HVAC heat exchanger will either heat or cool the ambient air with conduction.
Hence, they require the proper mean from which to get thermal energy.
Thus, for cooling, this is usually in the form of refrigerant gas.
How to Design Unit Qty and Single Chiller Unit Capacity？
For the reliable operation of the system,
And adapt to changes in air cooled chillers load, the unit should be designed multiple units.
Only in very special circumstances, such as small projects, insufficient room area, or investment difficulties, etc.
Can consider using only one unit.
When selecting multiple units,
Is the cooling capacity of a unit the same?
Mainly according to the system load, especially the min load.
For example, 3 units with the same capacity,
When the load is less, only need to operate one unit,
The unit still has high efficiency,
Then, it should be considered reasonable to configure 3 units of the same capacity.
Conversely, when the load is too small, and it is a very low load rate for a unit,
At this loading rate, the operating efficiency of the unit is very low,
Even when it doesn’t work properly,
Had better design a small unit, it can match the minimum load better.
For example, in an office building,
After normal off-hours,
There will always be a few people staying for a while,
The load at this time generally accounts for a small percentage of the full load value,
If the stand-alone capacity configuration is too large,
Centrifugal units will experience a surge,
Other types of units will also experience unstable operating conditions.
For example, there are 3 units,
There are 5 combinations of configurations with two large capacities and one small capacity at runtime.
However, there are only three operating combinations for the configuration of three units of the same capacity.
Therefore, in larger projects,
When the maximum load is very different from the minimum load,
Usually, use the combination of large and small unit capacity,
Conducive to the stable and economical operation of the system.
· What is HVAC chiller systems validation?
OQ may be described as:
“Documented confirmation that the system or subsystem operates.
Thus, as connected throughout all identified performing range”.
Thus, the component should be performed only when it verifies the OQ Test.
· How long should an HVAC chiller systems last?
Air conditioning units and air cooled chillers usually last around 15 years or so.
If you want your air cooled chillers air conditioning unit to last as long as possible?
You want to get it sustained semi-annually.
Hence, Your chiller systems should be sized precisely for your place.
· What is the most energy-efficient HVAC Chiller?

What types of vapor compression chillers for HVAC air conditioning?
Vapor compression chillers include many types of chillers, all can be applied in the HVAC systems.
Heat exchangers are the key components in a vapor compression chillers. These exchangers use the power of the refrigerant vapor to transfer heat from the low-pressure liquid to cold water.
In a refrigeration system, a refrigerant is compressed and heated in a vaporizer. The vaporized refrigerant is used to control the temperature of a process fluid, such as air or fuel, in a heat exchanger. The saturated liquid from the exchanger is then cooled and condensed in a condenser that creates cold water that then enters the chiller.

Difference between HVAC chiller and industrial chillers?
Industrial chiller is the equipment used to cool process water and keep the temperature at a given level. It has an inlet and outlet that allows either hot or cold fluids to be pumped through the machine. The fluid that enters the machine is usually water.
Process chillers are used in industries such as food processing, paper manufacturing, pharmaceuticals, pulp and paper mills, beverage plants, petrochemical plants etc.
The main function of a refrigeration system is to maintain a building cool or warm by removing heat from inside air with ventilation changes or by removing heat from process equipment using industrial chillers.
Industrial chillers are a very important component of the most modern processing plants. It not only provides cooling for the process water but it is also needed to cool the condensing equipment and compressors, which are exposed to high temperatures.
A process chiller is used to provide cooling for a single unit of equipment, provides cooling for an entire plant or facility.
Process chillers are more common in power plants compared to other facilities, due to its capability to work independently even when other parts of the plant are not working.
A process chiller is a device that is used to cool down the temperature of water. Process chillers are the most common type of chiller and are used in many industrial processes. Process chillers can be either air-cooled or water-cooled.
Process chillers are mainly used for air cooling purposes, while process chiller is mainly used for water cooling purposes.
1. Chiller systems is the “refrigeration source” that drives the cooling process within a central air conditioner. It works by removing heat from water, which is then distributed to the rooms in your home.
An external heat exchange system can be a chilling water circulation system or cooling tower. It utilizes a chilled pump and a chilled water pipeline to keep your building cool. Cold water is pressurized by the pump and sent to the pipeline in order to cool different rooms in your house. Heat is also taken away from each room with this process, which means that you’ll have a more comfortable environment.
A cooling water circulation system includes two key components: pumps and pipes. The water cooled chiller is a piece of equipment that functions by way of transferring heat. Once the temperature gets lowered, it also releases a large amount of heat. This energy would then be absorbed by the cooling water without altering its temperature. This cooling system pumps water from the chiller to a cooling tower. This heat is exchanged with the air in this tower and then sent back to the chiller.
Fan for cooling the room: It is installed in the room that needs to be cooled and used to blow the air cooled by chilled water into the room to accelerate heat exchange.
The purpose of a cooling tower fan is to reduce the water temperature in the cooling tower. The warmer “return water” will then heat up faster and be more likely to emit heat into the atmosphere.
How to judge the quality of a cooling towers？
The main function of the cooling tower is to discharge the heat of the air cooled condensers to the outside.
If chilled water cooling is used in shopping malls HVAC design, cooling towers are generally required.
The central air conditioning can be cooled by a closed cooling tower, which greatly saves the operating costs of use.
Many cooling tower manufacturers provide cooling samples with cooling tower selection curves.
According to the local environmental wet bulb temperature, cooling water volume, chilled water temperature in and out of the tower, check the curve diagram.
According to the cooling tower selection curve of the cooling tower manufacturer, according to the local environmental wet bulb temperature (in summer), cooling water volume, chilled water temperature in and out of the tower, check the curve, and consider the long-term operation efficiency reduction, a margin can be reserved.
Cooling tower work requires a constant flow of air.
Whether it is a natural draft cooling tower or mechanical equipment, the air source needs a certain height to work effectively.
As for the natural draft cooling tower, it is very reliable. If there is no electricity, it will automatically start to operate.
In addition to air, another factor is the temperature difference between air and chilled water.
The greater the temperature difference between them, the better the cooling effect and the greater the cooling effect.
The pollution of cooling towers is also reduced.
Regular maintenance of the cooling towers can avoid its impact on the industrial production process.
It not only ensures the good operation of the cooling tower, but also saves you expensive maintenance and expenses.
How to judge whether the cooling tower is good or bad?
First: The cooling tower is used for cooling water, so the first thing to ensure is performance.
We can turn to third parties, such as CTI certified products, whose performance is 100% guaranteed.
But be sure to figure out the difference between CTI certified and CTI certified products. Some manufacturers certify one product and sell another product. How can I see it clearly? Enter the query website, compare parameters, and configure. This is no problem. NS.
Second: Operating costs: This needs to be considered from the perspective of saving chilled water and electricity. The China Quality Certification Center has given the answer. Anyone who meets the standard will be certified.
Third, life: Because of the different materials, the lifespan is also very different. At present, cooling towers made of glass fiber reinforced plastics have a lifespan of 6-12 years. Of course, there are fewer, and some are more than 12 years. If the user maintains it, it will be longer.
If you use high-zinc plate G235, the service life can generally reach more than 20.
Of course, this is also related to chilled water quality.
Fourth: Other factors, such as environmental protection factors. The production process chillerof FRP towers is harmful to humans, and waste is difficult to dispose of. It will become the cause of enterprise exhaustion in the future. Steel towers are much better, and there is no worries.
Fifth: price factor,
Sixth: After-sales service,
What to do if there is a problem, do you have the technical ability to solve it, do you have the financial ability to solve it, do you have time to solve it, and whether you have the initiative to solve it.
How to Choose a Water Heater for HVAC System?
- Buildings without steam sources (such as hotels without boilers for kitchens, laundry rooms, etc.).
