Air-cooled heat pump units
The air-cooled heat pump units' features as follow:
1 air-cooled heat pump units of middle or small unit, applicable to 200-10000 square meters of buildings.
2 air conditioning systems, applicable of heating and cooling, and saves the boiler.
3 sets of outdoor installation, saves the freezing room and construction investment.
4 air-cooled heat pump units of energy efficiency can reach 90%, saving energy consumption, and greatly reduce the cost of users.
5. saves the cooling tower, reduces the investment in the additional equipments ,such as the pump dang the pipeline.
6 no need cooling water system, reduces power consumption, and more suitable for the areas lacking water
7.Perfect protection design such as anti-frost protection, high/ low pressure protection, water flow protection, high-temp protection, etc., and automatic defrost function, assuring the system to run safely and efficiently even in hard conditions.
The safety protection system of air cooled heat pump would include at least the following several aspects:
1) inspiratory pressure is too low
2) exhaust pressure is too high
3) hydraulic protection
4) water temperature too low
5) waterside heat water protection
6) compressor start-up time interval
7) compressor inside motor overheating protection
Air-cooled heat pump control at least include:
1) defrosting control
2) more compressor sequence control
3) energy regulation
4) downtime and display
remote control interface
(5) for remote operation parameters and the control unit set off, the unit operation parameters and fault content displayed in control terminals)
