冷凍システム
Document Type and Number:
Japanese Patent JP6380157
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an adsorption-type heat pump which can suppress the generation of dew condensation at an adsorber when filling a refrigerant which is collected to a refrigerant tank into a refrigeration cycle.SOLUTION: A refrigeration system comprises cooling water temperature detection means for detecting a temperature T1 of cooling water flowing in a cooling water circulation passage, and cooling water temperature detection means for detecting a temperature T2 of the cooling water flowing in the cooling water circulation passage. Then, an operation of refrigerant collection means is controlled at a stop of an operation of the refrigeration system, and an operation of refrigerant filling means is controlled on the basis of detection results of the cooling water temperature detection means and the cooling water temperature detection means. By this constitution, when a temperature of an evaporator 4 is high, and temperatures of first and second adsorbers 1 and 2 are low, the refrigerant filling means is not operated and when the temperatures of the first and second adsorbers 1 and 2 reach the temperature of the evaporator 4 or higher, the refrigerant filling means is operated, and the refrigerant can be filled into the refrigeration cycle.SELECTED DRAWING: Figure 3
