Abstract: A refrigerant sub-system includes a compressor, a condenser, an expansion valve, an evaporator, and a refrigerant-air heat exchanger. The compressor receives and compresses refrigerant. The condenser condenses the refrigerant and transfers heat from the refrigerant to a first fluid. The expansion valve expands the refrigerant. The evaporator vaporizes the refrigerant at the first pressure and transfers heat from a second fluid to the refrigerant. The refrigerant-air heat exchanger has a first operating mode and a second operating mode. In the first operating mode, the condenser is adapted to condense a first portion of the refrigerant from a vapor to a liquid, and the refrigerant-air heat exchanger is adapted to condense a second portion of the refrigerant from a vapor to a liquid and transfer heat from the second portion of the refrigerant to air.

Abstract: A heating, ventilation, and air conditioning system includes first and second fluids, a heat exchanger, a refrigerant sub-system, and at least one closed loop sub-system. The heat exchanger includes a membrane for channeling the first fluid through the heat exchanger and is disposed for heat transfer between the first fluid and the second fluid. The membrane defines an inlet having an inlet height relative to grade. The closed loop sub-system transfers heat from the heat exchanger to the refrigerant sub-system and includes an expansion tank containing the first fluid. A level of the first fluid within the expansion tank has a level height relative to grade. The expansion tank is positioned relative to the heat exchanger such that the inlet height is greater than the level height and the membrane is maintained in a collapsed configuration.

Abstract: A heating, ventilation, and air conditioning (HVAC) system includes a hot water sub-system including a first heat exchanger and a condenser, a cold water sub-system including a second heat exchanger and an evaporator, and a refrigerant sub-system for transferring heat from the cold water sub-system to the hot water sub-system. The first and second heat exchangers transfer moisture and heat between a liquid desiccant and air. The refrigerant sub-system includes a compressor, the condenser, an expansion valve, the evaporator, and a refrigerant-air heat exchanger. The condenser transfers heat from compressed refrigerant to the hot water sub-system. The evaporator transfers heat from the cold water sub-system to uncompressed refrigerant. The refrigerant-air heat exchanger transfers heat from a portion of the compressed refrigerant to air in a first operating mode, and transfers heat from the air to a portion of the uncompressed refrigerant in a second operating mode.
