In the industrial refrigeration industry in our general water as refrigerant industrial chiller is relatively common, but the water as refrigerant it is only applicable to the cooling temperature is over 0 DEG C, so refrigeration air conditioning system with more, of course, is very common in the chiller, air cooled chiller we are the.
The water is cooled in an evaporator of an industrial water chiller and then fed into a fan coil or directly injected into the air to regulate temperature and humidity. Then, water as refrigerant and what are the advantages or disadvantages?
The advantages of a chiller and water as coolant:
1. The freezing point of water is 0 degrees centigrade, and the standard evaporation temperature is 100 centigrade.
2, the water density is small, viscosity is small, relative resistance is also small, so the equipment size is smaller.
3. The water has large specific heat capacity, good heat transfer effect and less circulating water.
4. The chemical stability of the water is good, no burning, no explosion.
5, pure water as the coolant water cooled chillers, corrosion of units and pipelines, system safety.
6, water is non-toxic and is harmless to human body, food and the environment, so it is in the air conditioning system, or in industrial refrigeration system, water as refrigerant, can also be sprayed into the air conditioning and cleaning of air.
Two, then the water as refrigerant industrial chillers and what are the disadvantages:
1, the only drawback is water, high freezing point, limits its scope of application, and as a coolant close to 0 DEG C when using, should pay attention to antifreezing measures such as shell and tube evaporator of heat exchanger.
