Cold and heat recycling device for fresh air in room

Abstract

The invention discloses a cold and heat recycling device for fresh air in a room. The cold and heat recycling device comprises a heat exchanger with micro-channel heat pipes, a shell protector, fans and fan running controllers. The heat exchanger with the micro-channel heat pipes and the fans are mounted in the shell protector, the fans are mounted at the front of the heat exchanger with the micro-channel heat pipes, a flange used for separating inlet air from exhausted air is arranged in the middle of the shell protector, and the fan running controllers are connected with the fans and control the fans when the fans run. The components of the cold and heat recycling device for the fresh air in the room are placed on a movable windowsill via the shell protector. Owing to the mode, the cold and heat recycling device has the advantages that the cold and heat recycling device can be conveniently installed on a window without drilling a wall, energy is recycled when the fresh air is led into the room, and accordingly waste of the energy is reduced.

Description

Technical field [0001] The invention relates to the technical field of energy recovery and energy saving, in particular to a device for recovering cold and heat of fresh air in a room. Background technique [0002] In the prior art, the cold and heat recovery devices of fresh air in the room mainly use plate heat exchangers, rotary heat storage heat exchangers, etc., which are used in central air conditioning equipment. Most household split air conditioners do not contain fresh air introduction devices, and indoor air quality is poor. , It is often necessary to open windows to exchange fresh air. During the exchange process, the air in the room that has been adjusted for temperature and humidity will be lost in vain, wasting energy; some air conditioners also introduce some fresh air from the outside through the negative pressure of the evaporator. After this fresh air enters the room, The positive pressure formed in the room will exhaust the air in the room, the cooled air is ex...

Problems solved by technology

[0002] In the prior art, the cold and heat recovery device of fresh air in the room mainly adopts plate heat exchangers, heat storage heat exchangers with wheels, etc. for central air-conditioning equipment, and most household split air conditioners do not include fresh air introduction devices, and the indoor air quality is poor , It is often necessary to open the window to achieve fresh air exchange. During the exchange process, the air that has been adjusted in temperature and humidity in the room will be lost in vain, wasting energy; there are also some air conditioners that introduce some fresh air from the outside through the negative pressure of the evaporator. After this fresh air enters the room, The positive pressure created in the room pushes the air out of the room, cooling air in summer and heated air in winter, causing a lot of wasted energy
