Title:
HEAT STORAGE TYPE AIR CONDITIONER
Document Type and Number:
Japanese Patent JP3903292
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain stable cooling capacity or heating capacity by detecting the rate of the subcooling at the part between the joining part of a general cooling circuit and a chilling circuit, and a second restrictor and by controlling the opening rate of a first restrictor based on the detected value.
SOLUTION: Coolant piping 106, a third restrictor 22 and coolant piping 105 are connected sequentially on the other side of a coolant piping 112 of a heat storage type heat exchanger 10 and the coolant piping 105 is joined to a coolant piping 108 at a joining part M. Coolant subcooling detecting means 201 detects the subcooling degree of the coolant at the joining part M and a first opening rate controlling means 202 controls the opening rate of the first restrictor 6. When the value of (target coolant subcooling degree)-(detected coolant subcooling degree) is negative, the opening rate of the first restrictor is reduced and when positive, the opening rate is increased. With this, predetermined coolant subcooling temperature is obtained and only the liquid state coolant can be supplied to the second restrictors 15 a, b and c.
