Title:
排熱回収システム
Document Type and Number:
Japanese Patent JP6486500
Kind Code:
B2
Abstract:
A exhaust heat recovery system comprises: a transfer device for circulating a first refrigerant; an exhaust heat recovery heat exchanger for recovering exhaust heat from outside of a system; an exhaust heat supply heat exchanger that exchanges heat with the outside of the system to supply the exhaust heat to the outside of the system; an exhaust-heat heat exchanger that exchanges heat with the outside of the system to emit excess heat in the system to the outside of the system; an auxiliary heat exchanging device having a compressor, a first heat exchanger, an expansion device, and a second heat exchanger connected thereto sequentially by a pipe, a second refrigerant circulating in the auxiliary heat exchanging device; the exhaust heat recovery heat exchanger, the transfer device, the first heat exchanger, the exhaust-heat heat exchanger, the second heat exchanger, and the exhaust heat supply heat exchanger being connected sequentially by a pipe, the first refrigerant circulating in the exhaust heat recovery system, wherein the auxiliary heat exchanging device includes a controller, wherein when temperature of the first refrigerant flowing on an outlet side of the second heat exchanger is higher than an upper limit of a set temperature range, the controller controls a rotation speed of the compressor and an amount of throttle of the expansion device such that the temperature of the first refrigerant entering the exhaust-heat heat exchanger increases.
