McQuay United States launches its Swing-type Vega heat pump to reduce energy costs by recovering waste heat for room heating and domestic hot water, especially for hotels, hospitals, medical centers, schools, stadiums and manufacturing plants. The McQuay Scrollwind Ventilation Heat Pump can range from 500 to 3,000 MBh and heat water to 160 ° F (71 ° C). Tianwei heat pump using well-known closed scroll compressor, stable performance, low operating noise and the use of R134a environmentally friendly refrigerant. The R134a refrigerant is not detrimental to the ozone layer nor is it included in the list of refrigerants to be phased out. McQuay's open control protocol allows the crew to easily access building automation control systems by choosing to use BACnet®, LonTalk® or Modbus® open standard protocols. The optional hot gas bypass allows the unit to operate at part load as low as 10%. "Tianwei heat pump units are energy-efficient units," said Eddie Rodriguez, product manager, McQuay Scroll and Screw chillers. "Compared to gas heating, Tianwei heat pump units have lower heating costs and better return on investment. COPs (Performance Coefficients) range from 4 to 5, so investment costs can be recovered in one year or less Innovative heat recovery technology can reduce hundreds of tons of CO2 emissions per year, significantly reducing equipment carbon emissions In addition, Tianwei heat pump unit can improve the efficiency of building heating system to help owners obtain the LEED? Certification of buildings get the appropriate points. The use of Tianwei heat pump unit than the use of gas and electric heating are more economical and can reduce The investment cost in boilers and / or cooling towers, so heating places can reduce equipment investment and operating costs.
