量が増力口する。(Function) Since the present invention is configured as described above, when the temperature of the heat source water sent to the cooler drops in winter, etc., the inlet of the nuclear heat source water is automatically adjusted by detecting the temperature. By opening and closing the control valves of the U system, the heat source water is made to flow in parallel within the cooler in order to reduce the number of passes through the cooler's multi-circuit. This increases the amount of heat source water flowing through the cooler.

とが可能となる。(The fruit of the invention) As explained above, if the fc method is constructed in a non-inventive manner, it is possible to create a multi-circuit cooler consisting of multiple passes larger than the copass, and a multiple circuit cooler that ejects the heat source water inlet temperature. 9. It is equipped with a piping system equipped with a companion control valve for switching. When the temperature of the heat source water decreases, Ktk increases step by step to keep the temperature at the outlet of the heat pump cooler (iIA7), so there is no risk of freezing and the heat absorption is reduced to one element. Therefore, there is no need for public safety to control the capacity of heat pumps to limit heat absorption.Therefore, heat can be widely collected from fluid sources that are subject to natural temperature changes, such as water, sewage plants, etc. It is possible to enter.
