Title:
ABSORPTION TYPE HEAT PUMP
Document Type and Number:
Japanese Patent JP3147767
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To secure operational stability of an absorption type heat pump and the reliability of a solution pump.
SOLUTION: The primary sides of a regenerator 8, a rectifier 9 and a condenser 15 and the primary sides of a supercooler 16, an expansion valve 17 and a vaporizer 18 are connected to an absorber 14, a solution pump 6 and a solution heat exchanger by way of piping and a pump receiver 4 and a liquid level detection means 5, which detects the liquid level of the pump receiver 4 are provided above the solution pump 6 at the suction side of the solution pump 6. Furthermore, there is provided a control means which controls the liquid level of the pump receiver 4 to a definite value by controlling the rotary speed of the solution pump 6. Since a refrigerant solution can be supplied to the solution pump 6 constantly under a definite positive pressure as a result, the amount of circulation of the solution pump 6 is stable and effective to a stable operation of this system.
