the air cooled chiller condenser the refrigerant is compelled by the compressor via smaller bronze tubes which have svelte aluminum fins mechanically bonded to them. Ambient air is then forced through the condenser coil by the chiller fans. This reasons the peppery refrigerant gas to condense into a fluid [link widoczny dla zalogowanych], changing state [link widoczny dla zalogowanych], and releasing the heat that the gas collected at the chiller evaporator. The waste heat is then carried away into the ambient air by the fans. The fluid is then forced through the orifice and the process starts again.
The center of the chiller is the refrigeration compressor. This is a pump that uses electrical energy to pump refrigerant approximately the system. Depending on the applying like size or operating temperature, a assorted compressor pumping technology is used. Smaller chillers use refrigeration compressors like rotary compressors, scroll compressors, and reciprocating compressors. Larger chillers use refrigeration compressor like reciprocating compressors, screw compressors, digestion compressors [link widoczny dla zalogowanych], and centrifugal compressors.
Each type of refrigeration compressor tin operate hardly ever efficiently in the atmosphere cooled water chiller depending ashore the water or glycol channel temperature necessitated, the ambient air temperature conditions and the chiller refrigerant accustomed.
The efficiency of the chiller compressor is given by the COP or Coefficient of Performance which is the percentage of kW of heat removed to kW electrical input necessary. The higher the chiller COP is, the better the energy efficiency. For sample a COP of 3 method that for each 1 kW of electrical input, 3kW of heat is removed from the water. A chiller COP of 5 method that because each 1kW of electrical energy input, 5kW of heat energy is removed from the water.
Typically chiller COP will vary consist in ...:
1. Holding the chiller condensing temperature constant: a lower chiller evaporating temperature will use extra electrical power per kW heat removed and the chiller COP will be worse, meantime a higher chiller evaporating temperature will use fewer electrical power per kW of heat removed and the COP will be higher.
2. Holding chiller evaporating temperature constant: a higher chiller condensing temperature will have a aggravate chiller COP namely having a lower chiller condensing temperature.
A customers process cooling prerequisite will decide the operating temperature for the air cooled water chiller. For example one air conditioning chiller will require water typically by 7 deg C outlet from the chiller evaporator and 12 deg C return. This would require a chiller refrigerant favor R407C which is fine for ambient air contexts of up to 45 deg C.
Where a higher chiller water outlet temperature is required a chiller refrigerant gas like R134a would be attractive and this has the joined benefit of granting the chiller to operate in much higher ambient conditions
