摘要： A heating ventilation and air conditioning (HVAC) system includes a plurality of heating, ventilation and air conditioning (HVAC) units servicing a plurality of zones of a building. A plurality of controllers is connected to the plurality of HVAC units, each controller servicing one or more zones of the plurality of zones. The plurality of controllers include at least one first controller servicing at least one first zone that is powered off when the HVAC system is in a first operating mode and a second controller servicing a second zone of the plurality of zones that remains powered on when the HVAC system is in the first operating mode. The at least one second controller is operably connected to the at least one first controller to enable powering on of the first controller when an environmental condition in the second zone falls outside of a selected range.

摘要： There is provided a refrigeration system (10) comprising a compressor (12) having a suction (11) and a discharge (13), a heat rejecting heat exchanger. (14), an expansion valve (16), and a heat accepting heat exchanger (18). Preferably the system (10) comprises any one or more of: a pressure equalisation valve (4O3 42) for equalising the pressure differential between the compressor suction (11) and compressor discharge (13); a liquid valve (44), preferably a liquid solenoid valve or an electronic expansion valve, the liquid. valve (44) arranged in a flow line (24) between the heat rejecting heat exchanger (14) and the expansion valve (16); and a check valve (46), preferably a solenoid valve or an electronic expansion valve, arranged in a flow line (22) between the heat rejecting heat exchanger (14) and the compressor (12). The valves (40, 42, 44, 46) are operated in a variety of manners upon compressor shutdown and startup to avoid damage to the components of the compressor (12). Preferably the system further comprises means for heating at least one component of the compressor (12) and preferably also control means for activating the heating means when appropriate, such as when compressor startup is required, and starting the compressor after heating.

摘要： Refrigerant is circulated through a vapor compression system (20) including a compressor (22), a gas cooler (24), an expansion device (26), and an evaporator (28). When a sensor (66) detects that frozen water droplets form on the evaporator (28), a valve (60) positioned between the discharge of the compression (62) and inlet (64) of expansion device (26) is opened. Refrigerant from the discharge of the compressor (22) bypasses the gas cooler (24) and enters the inlet of the expansion device (26). The high temperature refrigerant melts the frost on the evaporator (28). As the frost melts, the passage of the evaporator is opened to allow air to flow through the evaporator.
