Abstract
An absorption cold/hot water generating machine comprising a refrigerating cycle formed by pipe-connecting an evaporator, an absorber, a solution heat exchanger, a low-temperature generator, a condenser, a high-temperature generator, a solution pump, and a refrigerant pump; the solution pump being an inverter-driven pump; a header for receiving a return solution from the high-temperature generator; a level sensor for detecting the liquid level in the header; and control means for controlling the flow rate of the solution sent from the absorber to the high-temperature generator by controlling the operating frequency of the solution pump, thereby keeping the solution level in the header within a prescribed range; wherein the control means includes sampling mode setting means for setting a solution sampling mode in which the discharge side pressure of the solution pump is brought to over a prescribed pressure through control of the operating frequency thereof.
