Screw water chiller and water source heat pump units refrigeration operation cost comparison
When it comes to using screw water chiller with water source heat pump units refrigeration operation cost
Differences, a lot of people think that use water source heat pump units refrigeration than use cold water machine
Set of refrigeration operation cost is low, that is not entirely correct. Produce this kind of view
The root cause is that the cooling water source heat pump weaving efficiency higher than that of water chiller, it is true that both
So, why is wrong? The operation cost of high and low and because of a system
Not only decided by the chiller operating cost. The need when water source heat pump units refrigeration
In underground water. The depth of the extraction of groundwater and is involved. Asked the groundwater resources expenses, etc
The topic. Also before the original RH5BW680HM type screw water source heat pump units as an example, its system
Cold quantity is 677 lw, input power for lt85kw, demand of groundwater is 57 m/h,
Cooling water in and out of the water temperature is 15 y/y. So every producing lookw cement heat pump units
Cooling capacity, power consumption of the unit for] 18.5/677 xtoo: 17.5 kW. The demand of groundwater
57/677 x1 [otters'/h = 85 m; if extraction of 8.5 m/h plant water needed for diving
Pump power more than 24.9-17.5 = 7.4 kw. Water source heat pump units in operation cost
More than the screw water chiller.
In the operating cost estimates, no considering groundwater water resources fee,
As the limited groundwater resources, because of the complexity of the technology of injection and injection of capital cost
With such issues, some enterprises can small to full recharge of groundwater, for this purpose, some to
Area has started to use water source heat pump water fees charged by the project. So, the specific
When projects, cost accounting, take into account the groundwater water resources fee to ask
Topic, consider to whether there are other energy available.
