摘要： A tandem compressor system is disclosed that delivers compressed refrigerant to a common discharge manifold, and then to a common condenser. From the common condenser, the refrigerant passes to a plurality of evaporators, with each of the evaporators being associated with a separate environment to be conditioned. A reheat function is provided by a reheat coil(s) for one or several environments such that desired temperature and humidity levels are achieved. Various reheat concepts and system configurations are disclosed, where the reheat coils are interconnected or independent from each other, as well as each evaporator is associated with a single or a plurality of the reheat coils.

摘要： A refrigerant system is provided where the functions of an economizer heat exchanger and liquid-suction heat exchanger are combined. The two configurations are disclosed with a single common heat exchanger construction. In a first configuration, a series of valves selectively routes only one of two possible refrigerant flows through a common heat exchanger such that a control can selectively activate either an economizer heat exchanger circuit or a liquid-suction heat exchanger function. In a second configuration, both refrigerant flows are passed to the common heat exchanger through separate fluid lines and are selectively activated by the control. Variations of the second configuration are also disclosed.

摘要： An expansion device for the heat pump applications consists of a flow resistance device that has a different resistance to refrigerant flow depending on the flow direction through this device. The flow resistance device has no moving parts so that it avoids the damage, wear and contamination problems of the moveable piston in the prior art. The flow resistance device is a fixed obstruction about which the fluid must flow when traveling through the expansion device.

摘要： Refrigerant is circulated through a vapor compression system including a compressor, a condenser, an expansion device, and an evaporator. Cold condensate forms on the evaporator surfaces as the refrigerant accepts heat from an air stream. The cold condensate drips down from the evaporator coil and collects in a condensate pan. In one example, the cold condensate is directed into a condensate heat exchanger to subcool the refrigerant exiting the condenser. In another example, the refrigerant exiting the condenser flows through a refrigerant line located in the condensate pan. In another example, the cold condensate is sprayed on the refrigerant line exiting the condenser or on the subcooling portion of the condenser. By utilizing the condensate for further subcooling of the refrigerant, system capacity and efficiency are enhanced. Various control techniques and condensate flow methods are also disclosed.

摘要： An air conditioning or refrigeration system includes an expansion device that has a plurality of operating positions. When the expansion device is in a fully open position, the expansion device provides an indication to a system controller regarding that position. The controller responsively determines if the fully open position of the expansion device is caused by an undesirably low amount of refrigerant charge in the system. In one example, the controller rules out other possible reasons for the expansion device being in the fully open position. In one example, the controller automatically shuts down appropriate portions of the system to avoid any component damage that may result from having too low refrigerant amount in the system.

摘要： A method for operating a vapor compression system includes the steps of providing a vapor compression system having a compressor circuit including a compressor having an inlet port and an outlet port, a circuit incorporating the compressor, a condenser, an evaporator and an expansion device for sequentially generating a cooling refrigerant for cooling a stream of air so as to provide a dehumidified cooled stream of air, and a reheat refrigerant for heating the dehumidified cooled stream of air to provide a reheated dehumidified stream of air; controlling discharge pressure from the compressor outlet so as to increase discharge pressure from the compressor outlet. Furthermore, system dehumidification performance is improved in terms of latent capacity boost, undesired sensible capacity reduction, latent efficiency enhancement, and recovery of supply air temperature to a desired level.
