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. Furthermore, the flow control device may be of an adjustable type (e.g. modulating or pulsating) to achieve variable sensible heat ratios and to cover a wide range of potential applications. Lastly, the bypass line may have extended heat transfer elements allowing heat transfer enhancement between the air and refrigerant.
