Waste heat recycling device for room

Abstract

The invention provides a waste heat recycling device for a room. The waste heat recycling device for the room comprises a heat pipe heat exchanger, a containing box, a heat recovery assembly and a heat utilization assembly; the heat pipe heat exchanger comprises an evaporation section for absorbing indoor heat and a condensation section for releasing heat, the containing box covers the out part ofthe condensation section, the heat recovery assembly is in communication with the containing box to take away the heat generated by the condensation section, the heat recovery assembly comprises a water pump and a first heat exchanger, wherein the first heat exchanger is in communication with the water pump, the water pump is in communication with the containing box through a water pipe so that water flow can flow through the condensation section and take away the heat, and the first heat exchanger is in communication with the containing box so that the heat can be transmitted to the first heat exchanger, the heat utilization assembly exchanges heat with the heat recovery assembly so as to utilize the heat brought by the heat recovery assembly. Compared with the mode that a draught fan isused for directly discharging the heat to the outside, the waste heat recycling device reduces energy consumption, recycles the heat and avoids energy waste, the water flow exchanges the heat with the heat pipe exchanger, the pipeline size is small, and pipe distribution is convenient; the heat exchange coefficient of the water flow is far larger than that of air, and the heat exchange efficiencyis improved.

Description

technical field [0001] The invention relates to the technical field of waste heat recovery and utilization, in particular to a waste heat recovery and utilization device for a room. Background technique [0002] The substation of the subway station will generate a lot of heat, and direct ventilation is generally used to cool down in winter or transitional seasons; however, due to the high heat generation in the room, the fan used has a large air volume, which will cause large energy consumption and noise. At the same time, the heat generated by indoor equipment is directly discharged to the outside, which also causes a waste of energy. Contents of the invention [0003] The invention provides a waste heat recycling device for a room to solve the technical problem in the prior art that the heat generated in the substation of a subway station is directly discharged to the outside through a fan, resulting in high energy consumption and energy waste. [0004] In order to achi...
