冷凍装置
Document Type and Number:
Japanese Patent JP3577891
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make the entire construction of a refrigerator compact by realizing a refrigerant system suitable for reducing environmental problems and a power demand and using appliances which constitutes the system for other purposes besides their original purposes in a refrigerant system which is provided with a plurality of refrigerant circuits and in which a heat exchange is carried out between refrigerant circuits. SOLUTION: In a secondary refrigerant system provided with a primary side refrigerant circuit A and a secondary side refrigerant circuit B, the primary side refrigerant circuit A is composed of an absorption type refrigerating cycle. A drive power generating circuit T provided with a pair of tanks T1, T2 is connected with the liquid side of the secondary side refrigerant circuit B. A drive heating heat exchanger 4 is provided between a condenser 3 of the primary side refrigerant circuit A and a main heat exchanger 5 which works as an evaporator. During a cooling operation, a cold heat is given to the secondary side refrigerant circuit B by a heat exchange at the main heat exchanger 5 and a low pressure is generated in one tank T2 by cooling the refrigerant in the drive power generating circuit T. With the heat exchange at the drive heating heat exchanger 4, the refrigerant in the drive power generating circuit T is heated to generate a high pressure in other tank T1. With such a pressure, the refrigerant is forced to circulate in the secondary refrigerant circuit B.
