Title:
HEAT-RECOVERY-TYPE REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/182458
Kind Code:
A1
Abstract:
 In a first operation mode, a comparison is made between: a first liquid pipe temperature, which is the temperature of a cooling medium on the usage-side heat exchanger (52a, 52b, 52c, 52d) side of a liquid pipe heat exchanger (45) for exchanging heat with a cooling medium flowing on the liquid side of a plurality of heat-source-side heat exchangers (24, 25); and a second liquid pipe temperature, which is the temperature of the cooling medium on the heat-source-side heat exchanger (24, 25) side of the liquid pipe heat exchanger (45), and when evaporation-switching liquid pipe temperature conditions are satisfied, a second operation mode is entered, in which the heat-source-side heat exchanger (24), functioning as a radiator for the cooling medium, is switched to an evaporator for the cooling medium, and the plurality of heat-source-side heat exchangers (24, 25) are caused to function as evaporators for the cooling medium.
