Abstract: A heat pump is provided with a discharge valve on a discharge line. The discharge valve can be positioned to modulate or pulse refrigerant flow from the discharge line heading toward an indoor heat exchanger, when in a heating mode. By providing this restriction, the pressure and the temperature of the refrigerant increases. This increased temperature provides additional heating capacity as well as increases the temperature of the delivered indoor air, minimizing “cold blow” and making the end user more comfortable. The use of discharge valve can also minimize or entirely eliminate the ON/OFF unit cycling, as the amount of heat delivered can be precisely controlled by pulsing or modulating the valve, thus reducing unit cycling losses, improving user comfort and enhancing reliability.

Abstract: A refrigerant system is provided with an unloader bypass line to selectively unload the compressor and deliver refrigerant from a partially (or fully) compressed location back to a suction port of the compressor. A section of this unloader bypass line is placed in the path of air having passed over an evaporator and towards an environment to be conditioned. This section of the unloader bypass line would contain refrigerant that is at a higher temperature than the refrigerant, which had been delivered into the evaporator by the main circuit. In this manner, this bypass line section will provide the function of reheating the air above the temperature to which it had been cooled in the evaporator to achieve a desired humidity level. Thus, the reheat function is obtained without requiring a dedicated reheat loop, associated components and additional structure. Also, through the refrigerant temperature reduction, compressor reliability and performance are improved.
