The refrigerator for the vehicle may include a cavity or compartment accommodating a product, a machine room disposed at a side of the cavity, a compressor accommodated in the machine room to compress a refrigerant, a condensation module or assembly accommodated in the machine room to condense the refrigerant, an evaporation module or assembly accommodated in the cavity to evaporate the refrigerant and thereby to cool the cavity, a machine room cover defining an inner space of the machine room, and a controller mounted on an outer surface of the machine room cover.

Disclosed are climate systems and methods for control the climate systems. A climate system includes a plurality of compressors, a first heat exchanger disposed downstream of the compressors and a second heat exchanger disposed downstream of the first heat exchanger. The compressors and heat exchangers are fluidly connected by refrigerant lines to form a refrigerant circuit. The climate system also includes a controller that controls the operation of the compressors to draw back lubricant to the compressors without use of an oil equalization system.

A refrigeration cycle device includes a high-temperature side heat exchanger, an expansion valve for decompressing the refrigerant flowing out of the high-temperature side heat exchanger, a low-temperature side heat exchanger that exchanges heat between the refrigerant decompressed by the expansion valve and coolant, a high-temperature coolant circuit in which the coolant circulates to the high-temperature side heat exchanger, a low-temperature coolant circuit in which the coolant circulates to the low-temperature side heat exchanger, a battery and a low-temperature side radiator configured to exchange heat with the coolant in the low-temperature coolant circuit; and a heat transfer portion configured to transfer heat from the high-temperature coolant circuit to the low-temperature coolant circuit such that the coolant dissipates heat in the battery and the low-temperature side radiator.

A heat pump system may include first and second cooling devices, a battery module, and a chiller to enable simplification of a system by heating or cooling the battery module by one chiller in which a coolant and a refrigerant exchange heat and a main heat exchanger provided in an air conditioning device is connected to each of first and second coolant lines so that the coolant circulated in each of the first and second cooling devices passes through the main heat exchanger, the refrigerant passing through the main heat exchanger exchanges heat with the coolant supplied through the first coolant line and exchanges heat with the coolant supplied through the second coolant line, and a flash tank separating refrigerants which have exchanged heat into a gaseous refrigerant and a liquid refrigerant and selectively discharging the gaseous refrigerant and the liquid refrigerant may be provided in the main heat exchanger.

This disclosure discloses a heat pump air-conditioning system and an electric vehicle. The system includes a HVAC assembly, a compressor, and an outdoor heat exchanger. The HVAC assembly includes an indoor condenser, an indoor evaporator, and a damper mechanism. The damper mechanism selectively opens ventilation channels of the indoor condenser and/or the indoor evaporator. An outlet of the compressor communicates to an inlet of the indoor condenser. An outlet of the indoor condenser communicates to an inlet of the outdoor heat exchanger selectively through a first throttle branch or a first through-flow branch. An outlet of the outdoor heat exchanger communicates to an inlet of the indoor evaporator selectively through a second throttle branch or a second through-flow branch. Both an outlet of the indoor evaporator, the outlet of the indoor condenser, and the outlet of the outdoor heat exchanger communicate to an inlet of the compressor.

A heat pump cycle includes a compressor, a first interior heat exchanger, a separator that separates a refrigerant discharged from the compressor into a gas-phase refrigerant which does not include a lubricant and a remaining refrigerant, an exterior heat exchanger that performs heat exchange between the remaining refrigerant flowing out of the separator and an outside air, a second interior heat exchanger, a control valve, an accumulator, and a first bypass passage that bypasses the second interior heat exchanger and connects to an inlet side of the accumulator. The heat pump cycle heats an air flow in the first interior heat exchanger and controls the control valve to reduce the pressure of the refrigerant, in a state where the refrigerant circulates in a refrigerant circuit including the first bypass passage while accumulating the gas-phase refrigerant flowing out of the separator in the second interior heat exchanger.
