Title:
COMPRESSION ABSORPTION HYBRID SYSTEM AND OPERATING METHOD FOR THE SAME
Document Type and Number:
Japanese Patent JP2023143660
Kind Code:
A
Abstract:
To provide a compression absorption hybrid system capable of further enhancing efficiency by performing control for increasing power COPc when supplying cold, and an operating method for the same.SOLUTION: As for an intermediate temperature that means intermediate pressure as pressure between low pressure of a refrigerant in a low-stage side circuit 100a and high pressure of the refrigerant in a high-stage side circuit 100b, by at least using at least either one of a condensation temperature in a condenser changing depending on an environment and an operating load or an absorption temperature in an absorber and a regeneration temperature in a regenerator RG, a target intermediate temperature enabling increase in power COPc as power COP when cold is supplied is derived, and by setting the target intermediate temperature as a target value of the intermediate temperature, rotational frequency of a solution pump P is controlled.SELECTED DRAWING: Figure 1
