摘要： A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, a modulating valve, and a liquid-cooled alternate condenser. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The secondary condenser receives the second airflow and outputs a third airflow to the primary condenser. The primary condenser receives the third airflow and outputs a dehumidified airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the modulating valve. The modulating valve directs the flow of refrigerant to the primary condenser and to the alternate condenser. The alternate condenser receives a portion of the flow of refrigerant and transfers heat from the refrigerant to a flow of fluid.

摘要： A dehumidification system includes a compressor, a primary evaporator, a primary condenser, a secondary evaporator, a secondary condenser, a plurality of posts, and a drain pan. The secondary evaporator receives an inlet airflow and outputs a first airflow to the primary evaporator. The primary evaporator receives the first airflow and outputs a second airflow to the secondary condenser. The drain pan captures water removed from the first airflow by the primary evaporator. The secondary condenser receives the second airflow and outputs a third airflow to the primary condenser. The primary condenser receives the third airflow and outputs a fourth airflow. The compressor receives a flow of refrigerant from the primary evaporator and provides the flow of refrigerant to the primary condenser.

摘要： A heat pump includes a refrigerant loop. The refrigerant loop includes a compressor, a first condenser, a vapor generator having a first region and a second region, a first expansion valve, a second expansion valve, and a first evaporator. A branching point is positioned between the first condenser and the vapor generator. The branching point diverts a portion of a first heat exchange fluid circulating through the refrigerant loop to the vapor generator. The first expansion valve is positioned between the branching point and the vapor generator. An outlet vapor generator is coupled to a mid-pressure inlet port of the compressor.

摘要： A multiple-circuit heating and cooling system includes a first refrigeration circuit having a first condenser and a first evaporator and a second refrigeration circuit having a second condenser and a second evaporator. The first condenser and the second condenser are arranged in a first row split configuration, and the second condenser is downstream of the first condenser relative to a first air flow directed across the second condenser and the first condenser. Additionally, the first evaporator and the second evaporator are arranged in a second row split configuration, and the first evaporator is downstream of the second evaporator relative to a second air flow directed across the first evaporator and the second evaporator.

摘要： A system and method for reducing the refrigerant charge in a refrigeration system by preheating the liquid refrigerant before it is introduced to the evaporator inlet. When refrigerant liquid is introduced to the evaporator inlet, a portion of the refrigerant liquid vaporizes. This refrigerant vapor displaces refrigerant liquid at the inlet of the evaporator. As more refrigerant vapor is introduced, the amount of liquid inside the evaporator is reduced. A heat exchanger is placed before the liquid refrigerant inlet of the evaporator to generate more vapor when the refrigerant enters the evaporator.

摘要： A heat pump system including a compressor mounted on a refrigerant circulation line for compressing and discharging refrigerant. An internal heat exchanger is mounted inside an air-conditioning case. An evaporator is mounted inside the air-conditioning case. An external heat exchanger is mounted outside the air-conditioning case. Refrigerant discharged from the internal heat exchanger is selectively expanded between the internal heat exchanger and the external heat exchanger. Refrigerant is also expanded along the refrigerant circulation line at an inlet side of the evaporator. A coolant circulation line is configured to circulate coolant toward electronic units of the vehicle. A refrigerant-coolant heat exchanger is configured to exchange heat between the refrigerant flowing the refrigerant circulation line and the coolant circulating through the coolant circulation line.

摘要： A vapor injection heat pump includes a coolant loop and a refrigerant loop. The refrigerant loop includes a compressor, a valve directing a refrigerant of the compressor to a first or second heat exchanger dependent upon a mode of operation, an expansion device receiving the refrigerant from at least one of the heat exchangers, a separator receiving an expanded liquid/vapor refrigerant mix from the expansion device and directing a vapor component to a first input port of the compressor and a liquid component to a second valve. The second valve directs the liquid component to the heat exchangers, dependent upon the mode, and an accumulator receives an output refrigerant of the heat exchangers dependent upon the mode and directs a vapor component to a second input port of the compressor. A control module controls a pump in the coolant loop and the first and second valves dependent upon the mode.
