McQuay water source heat pump single screw WPS.B main unit, 2B for two heads, a single screw McQuay McQuay water source heat pump has the following characteristics: single-screw McQuay water source heat pump has the following characteristics: 1 Available sources: groundwater, surface water, soil, domestic wastewater, industrial wastewater, and a variety of heat deep lake drainage. 2 uses heat pump technology to collect soil or groundwater in the energy, to ensure the summer cooling and winter heating of the building, while providing water for more than 45 ℃. Unit 3 boiler heating system is not required, no combustion process, to avoid the smoke pollution; cooling eliminates the need for cooling towers, cooling towers to avoid the noise and mold growth, in line with environmental requirements. Advanced load balancing principle, the main bearing design life of up to 100,000 hours. Four pairs of compressor design, starting current, has a good standby function and excellent part load performance. 5 stepless power adjustment, freezing temperature precise control 6 McQuay fourth generation of single screw compressor, the unique design of the star wheel and rotor zero clearance fit. Unit 7 is a multi-purpose machine, eliminating the need for boilers, cooling towers and facilities, investment costs only traditional heating and cooling system 1/2 ~ 1/3. While the small size of the unit, a small area of ??the room required for installation. 8 new microcomputer control, Chinese LCD screen, with a communication interface, enabling wireless remote monitoring unit (optional). It also can multi-machine joint control, the studio computer monitor (optional), and access to the building automation system (BAS). 9 unit testing ensures reliable plant operation, the test platform through the United States ARI certification. Failure McQuay water source heat pump unit is mainly single screw prone to have: a low pressure alarm whole units, can not run (the evaporator is the cracking); refrigeration compressor noise subtraction when the unit is running load two big noise; 3 McQuay Refrigeration The total gate unit tripped, that the core part of the refrigeration unit ---- refrigeration compressor coil burnt.
