Abstract: Multi-circuit refrigerant systems are provided with better control over a dehumidification function. In one embodiment, system circuits have means of communication with each other through connecting lines and flow control devices operable on demand. In another embodiment, a single reheat heat exchanger is utilized for both circuits, ensuring heat transfer interaction between the circuits. In yet another embodiment, a control unit operates refrigerant circuits in such a way that if some circuits are in a reheat mode, the remaining circuits are either shut off or are in an enhanced reheat mode.

Abstract: 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.

Abstract: 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.

Abstract: A tandem compressor refrigerant cycle with an economizer circuit is introduced to provide additional capacity and improve system efficiency. In this system, tandem compressors deliver 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. Each of the evaporators is associated with one of the plurality of compressors. By utilizing the common condenser, and yet a plurality of evaporators, the ability to independently condition a number of environments is achieved without the requirement of the same plurality of separate complete refrigerant circuits for each of the environments. In some embodiments, several of the plurality of compressors can be provided by compressor banks having its own plurality of compressors. Some of the compressors in the compressor bank can have intermediate injection ports to accept refrigerant vapor from the economizer circuit. In particular, the economizer circuit provides additional capacity to the evaporators with relatively high load requirements.

Abstract: 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.
