Title:
COOLING APPARATUS
Document Type and Number:
Japanese Patent JP2709890
Kind Code:
B2
Abstract:
PURPOSE: To increase a cooling capability of a refrigerant condenser in a freezer, and reduce the consumed amount of water of the refrigerant condenser and the amount of waste heat into a room.
CONSTITUTION: In a refrigerant circuit of a freezer, refrigerant gas compressed by a compressor 11 is condensed by the successive passage through a primary air cooled condenser 13, a water cooled condenser 14, and a secondary air cooled condenser 15 and led from an expansion valve 18 to an evaporator 19 for evaporation and hence for freezing action and is further circulated to the compressor 11 while an automated water supply valve 21 is provided on a cooling water passage 12 to the water cooled condenser 14, whereby the automated water supply valve 21 is opened when a temperature condition is severe to actuate the water cooled condenser 14.
