Comparison Between Air - Cooled Unit And Water - Cooled Chiller
Aug 17, 2017

Comparison of the operating costs of the air-cooled heat pump unit and the water-cooled chiller 1. Comparison of the power consumption: compare the power consumption of the two should be clear the difference between the installed capacity of the unit and the power consumption and the load distribution on the unit efficiency and power consumption The At full load, the condensing temperature of the air-cooled chiller is higher than that of the water-cooled unit. Therefore, the compressor of the air-cooled chiller needs more power, but the air conditioning load is distributed and uneven throughout the summer. The maximum time to run the load is extremely limited. The condensing temperature of the air-cooled chillers depends on the outdoor dry bulb temperature, while the condensing temperature of the water-cooled chillers depends on the outdoor wet bulb temperature. Within a day, the outdoor air dry bulb temperature changes much more than the wet bulb temperature, in arid areas can even reach 15 ℃ -16 ℃, while the wet bulb temperature is changing within a day is so small can be considered water-cooled The condensing temperature of the unit is almost constant within one day, and the condensing temperature of the air-cooled unit decreases as the outdoor dry bulb temperature decreases. 2, the comparison of maintenance costs: air-cooled chillers in the maintenance of the unit itself only need to maintain and water-cooled chiller unit not only to the maintenance of the unit also need a lot of cooling facilities, cooling towers which maintenance costs are particularly large, Such as fan motor bearing replacement, pump bearing, the replacement of the sleeve, the cooling tower and so on.
