Industrial chillers are a kind of refrigeration system that helps in cooling down a process fluid or air dehumidification in several commercial and industrial areas. It will utilise either a vapour firmness or absorption cycle to bring cooling effect. Chilled water has varied use starting from cooling to process utilization. An industrial chiller is usually given rate between 1 to 1000 tons of cooling energy. There are three kinds of chillers are water and evaporative condensed chillers and under them are 4different sub-categories that is reciprocating, screw driven, centrifugal and absorption chiller. The first three kinds are mostly powered by steam, electric motors and gas turbines. But the absorption chiller is given power by heat source like steam. An industrial chiller consists of following components through which it creates refrigeration that is an evaporator, condenser, compressor and an expansive valve. The evaporator usually works at lower pressure as well as lower temperature than that of condenser.
Lets us discuss on how an industrial chiller works?
Well, in a superlative cycle the condenser functions as a two fold component. Prior to condensation the high pressure vapour must be saturated. Good amount of heat must be passed from refrigerant to slow down the temperature to the saturation temperature. This is the point where condensation starts. When heat flows from refrigerant vapour tap air, the refrigerant quality will decrease till it has completely condensed. Mostly, it occurs in the condenser outlet. But in real, sub cooling i expected at condenser outlet. This sub cooled liquid offers insurance against liquid flashing as the refrigerant suffers loss in pressure in the tubing and components. Then the refrigerant to become a good het transfer medium has to undergo some alteration that is a temperature reduction. It is achieved by decreasing the pressure. It is because according to infallible law, when a pressure of a saturated liquid is decreased, the law governing its survival needs it to presume the saturation temperature at the new pressure. The thermostatic expansion valve help in reducing the pressure as it is a superheat control that helps in maintaining a constant vapour pressure. It offers the restriction required to decrease the pressure to some level that is determined by the size of the compressor, expansion valve, and load demand as well as system conditions. The liquid that is lost in boiling process states the enhancement in the refrigerant quality. Higher the difference between the liquid temperature and the evaporator temperature, higher the amount of liquid that is to be boiled to get the new saturation temperature. The whole cycle continues till refrigerated pace temperature is satisfied.
If you are thinking about maintenance of industrial chillers, then you must know that they are designed in such way that they will perform at its high efficiency. Maintenance needs to be done on a regular basis that will help in work guarantee of the chillers and it will work at an optimized level.
Envisys Technologies offers high quality industrial chillers that give a high performance and last long without any problem. It is available in affordable prices.
