An in-vehicle absorption heat pump device comprises a regenerator; an in-vehicle heat source for heating the absorbent in the regenerator; a gas-liquid separator; a condenser for condensing gas phase separated from the absorbent; an evaporator for evaporat...

A vehicle air conditioner, which can suppress the occurrence of an abnormal noise when switching the operation mode of air conditioning, is provided. The vehicle air conditioner comprises compression means 11 for compressing a heating medium, pressure redu...

The disclosure relates to a unitary heat pump air conditioner (100) having a plate type hot-side heat exchanger assembly (102), a cold-side heat exchanger assembly (110), and electrically driven compressor (112) and coolant pumps (114, 116). The plate type...

An air-conditioner for a vehicle includes a vapor-compression refrigeration cycle, a determination unit and a controller. The refrigeration cycle includes a compressor for compressing refrigerant, an inside condenser for exchanging heat between refrigerant...

The method involves measuring a pressure (Pd) at an outlet of a compressor, and measuring a temperature (Tev) of air flow, infront or behind an evaporator (12). The temperature of air flow, infront or behind the evaporator is estimated. The temperature of ...

The system comprises a compressor (10), an outside heat exchanger (24), and an evaporator (20) and condenser (22) both positioned internally of a space such as a vehicle cabin. In a cooling mode, the compressor (10) circulates refrigerant around the outsid...

A heat pump air conditioning system having an outside heat exchanger (24) which is disposed in an engine compartment (31) of a vehicle is provided. The outside heat exchanger (24) consists of a first outside heat exchanger (12) disposed forward of an engin...
