Heat extraction device for low-grade heat source

Abstract

本实用新型公开了一种低品位热源热量提取装置,本实用新型包括由热交换介质输送管依次连接循环回路的蒸发器、双级压缩机、高压冷凝器和中间冷却器,所述的蒸发器为所述热交换介质和低品位热源的热交换器,所述的高压冷凝器为所述的热交换介质和用热介质的热交换器,高压冷凝器的热交换介质出口之后分成两个支路,中间冷却器为两个支路的热交换器。本实用新型从而实现从低品位热源提取热量,本实用新型能够实现从25度以下的热源提取热量来生产70度以上的热水。
The utility model discloses a heat extraction device for a low-grade heat source. The heat extraction device for the low-grade heat source comprises an evaporator, a dual-stage compressor, a high-pressure condenser and a middle cooler, wherein the evaporator, the dual-stage compressor, the high-pressure condenser and the middle cooler are sequentially connected through a heat exchange medium conveying pipe to form a circulating loop, the evaporator is a heat exchanger for a heat exchange medium and the low-grade heat source, the high-pressure condenser is a heat exchanger for the a heat exchange medium and a heat consuming medium, the heat exchange medium is divided into two branches after getting out of an outlet of the high-pressure condenser, and the middle cooler is a heat exchanger for the two branches. According to the heat extraction device for the low-grade heat source, the purpose of extracting heat from the low-grade heat source is achieved, and the heat extraction device can achieve the purpose that heat is extracted from the heat source with the temperature lower than 25 degrees to be used for producing hot water with the temperature higher than 70 degrees.
