摘要： A refrigeration system with pressure balancing function includes a condensing unit, a first refrigerant delivery pipeline, and a pressure balance control device including a temperature control unit, a first refrigerant control valve and a refrigerant supply switching controller. The temperature control unit determines if the temperature of the evaporator is abnormal, generates a temperature adjustment trigger signal that shifts between adjustment level and non-adjustment level. The refrigerant supply switching controller will determine, based on the level of the temperature adjustment trigger signal, whether to output the valve-open signal to the first refrigerant control valve. When the temperature adjustment trigger signal received by the refrigerant supply switching controller is at the adjustment level, the refrigerant supply switching controller will not output the valve-open signal to the first refrigerant control valve, so that the first refrigerant control valve is closed to stop delivering the refrigerant to the first refrigerant delivery pipeline.

摘要： A diagnostic monitoring system and method is employed for one or more vapor compression systems such as air conditioners and heat pumps having a compressor, an indoor air handler fan coil and an outdoor condensor. Temperature, voltage and current sensors are provided at the outdoor condensor to determine that at least one vapor compression system is operating properly. Data obtained from the sensors is wirelessly transmitted to a receiving-device for use by the systems' custodian or repair service provider and includes information concerning an occurrence of periods when one or more of the vapor compression systems are operating at an abnormal state.

摘要： Systems and methods for reducing refrigerant pressures within an HVAC system are provided. A first tube may couple to a receptacle and to a manifold, placing the receptacle in fluid communication with the manifold. The manifold may couple to a condenser and may receive refrigerant from an outlet of a first pass of tubing through the condenser. Refrigerant exiting the first pass of tubing of the condenser may migrate into the receptacle in response to high refrigerant pressures within the HVAC system. A controller may determine whether at least one condition indicating a likelihood high refrigerant pressure within the HVAC system is present. The controller may close a first valve in response to determining that at least one condition indicating a likelihood high refrigerant pressure is present and upon the expiration of a first period of time. The first valve may couple to the first tube and may permit refrigerant flow into or out of the receptacle when open. The first valve may prevent refrigerant flow into or out of the receptacle when closed. Upon expiration of a second period of time, the controller may open the first valve.
