Refrigerant circulation apparatus with controlled operation of an evporator for on-vehicle battery cooling
First Claim
1. A refrigerant circulation apparatus comprising:
- a vehicle-interior air conditioner configured to cool an interior of a vehicle;
an on-vehicle battery cooler including an evaporator for on-vehicle battery cooling configured to cool an on-vehicle battery mounted on the vehicle;
an electric compressor configured to compress and supply a refrigerant to one or both of the vehicle-interior air conditioner and the on-vehicle battery cooler;
a temperature detection unit configured to detect a temperature of the electric compressor;
a pressure detection unit configured to detect a pressure of the refrigerant compressed by the electric compressor; and
a control unit configured to restrict operation of the evaporator for on-vehicle battery cooling so as to reduce load on the electric compressor based on the temperature of the electric compressor and the pressure of the refrigerant.

Abstract
A refrigerant circulation apparatus includes: a vehicle-interior air conditioning (2) that cools an interior of a vehicle; an on-vehicle battery cooler (3) that includes an evaporator for on-vehicle battery cooling (32) that cools an on-vehicle battery mounted on the vehicle; and an electric compressor (5) that compresses and supplies a refrigerant to at least one of the vehicle-interior air conditioning (2) and the on-vehicle battery cooling (3). The apparatus also includes: a temperature sensor (41) that detects a temperature of the electric compressor (5); a pressure sensor (42) that detects a pressure of the refrigerant compressed by the electric compressor (5); and a control unit (40) that restricts operation of the evaporator for on-vehicle battery cooling (32) to reduce load on the electric compressor (5) based on the temperature of the electric compressor (5) and the pressure of the refrigerant.
