Heat pump apparatus

Abstract

A heat pump apparatus that is capable of suppressing an increase in the installation area therefor and volume thereof is provided. A heat pump apparatus includes a compressor that compresses refrigerant, a condenser that liquefies the compressed refrigerant, and an evaporator that evaporates the liquefied refrigerant, wherein the condenser and the evaporator are plate-type heat exchangers formed in rectangular cuboid shapes, and the condenser, which is a plate-type heat exchanger, and the evaporator, which is a plate-type heat exchanger, are disposed next each other.

1 . A heat pump apparatus comprising:
 a compressor that compresses refrigerant;   a condenser that liquefies the compressed refrigerant; and   an evaporator that evaporates the liquefied refrigerant, wherein the condenser and the evaporator are plate-type heat exchangers.   
     
     
         2 . A heat pump apparatus according to  claim 1 , further comprising:
 a controller that controls driving of the centrifugal compressor;   an oil separator that separates refrigerant discharged from the centrifugal compressor from lubricating oil; and   a gas-liquid separator into which the refrigerant that has flowed out from the evaporator flows, that separates gas refrigerant and liquid refrigerant, and that supplies the evaporator only with the gas refrigerant,   wherein the condenser and the evaporator are disposed next to each other, and the oil separator is disposed on the same plane as the condenser and the evaporator;   the controller is disposed above one of the condenser and the evaporator;   the gas-liquid separator is disposed above the other one of the condenser and the evaporator; and   the centrifugal compressor is disposed above the oil separator.
