Heater And Chiller Hire, Including Air Cooled Chillers
We offer heater and chiller hire to businesses to help keep the temperature just right in your office. Whether its summer or winter, we can make that happen for you,[link widoczny dla zalogowanych], and we also offer air cooled chillers to rent.
During the cold winter months, it is important to keep your employees warm whilst they work. As well as it being a health and safety issue, it will keep them on the right side and improve their work efficiency and ethic. We offer a heater hire service where you can hire heaters from us to help keep the temperatures up in the office. Instead of buying one, you can just rent it for whenever you need it.
In the summer, you may need a chiller hire service instead,[link widoczny dla zalogowanych], which is something we also offer. If it gets too hot then these are ideal to keep cool you down whilst youre indoors. One of the types that we provide are called air cooled chillers, which get rid of heat from water and other process fluid using a refrigeration system which then dispenses the same heat into the air around you. It works by using the change of state of a refrigerant gas which is forced through an orifice at high pressure. This makes it change from a liquid to a gas and absorbs heat via the chiller evaporator heat exchanger.
The cold gas then travels to the chiller refrigeration compressor where it is turned into a hot, dense gas and then pumped to the chiller condenser. The amount that the compressor can pump and the refrigeration gas used,[link widoczny dla zalogowanych], as well as the operating conditions decide how much heat is taken out.
The most important part of a chiller is the refrigeration compressor, as it is a pump that uses electrical energy to pump refrigerant around the unit. A different compressor pumping technology is required for varying systems depending on application like size or operating temperatures. Smaller ones have refrigeration compressors like rotary compressors, scroll compressors, and reciprocating compressors. On the other hand, larger chillers tend to use refrigeration compressor like reciprocating compressors, screw compressors, absorption compressors, and centrifugal compressors.
Every type of refrigeration compressor can function more or less efficiently in the air water cooled chillers depending on the water or glycol outlet temperature that is required,[link widoczny dla zalogowanych], plus the ambient air temperature condition as well as the chiller refrigerant that is used.
The level of efficiency of it is determined by the COP, also known as the Coefficient of Performance, which is simply the ratio of kW of heat taken out to kW electrical input that is required. The higher the COP, the better the energy efficiency is. As an example, a COP of 3 means that for every 1 kW of electrical input, there is 3kW of heat taken out from the water. If the chiller COP is 5 then it means that for every 1kW of electrical energy input, 5kW of heat energy is dispensed from the water.Topics related articles：
