Embodiment 1

[0028] Such as figure 1 As shown: In winter, the indoor temperature in the north is generally much higher than the outdoor temperature. In order to ensure indoor ventilation, fresh air devices are usually installed to ventilate the room. The temperature of the gas discharged by the fresh air device will be higher than the temperature of the outdoor air, and these higher temperature gases are directly discharged into the outdoor air, resulting in direct waste of heat energy in this part of the gas and a waste of energy.

[0029] The outer top of the outer cover 3 is a closed cylinder, the inner diameter of the outer cover 3 is greater than the outer diameter of the chimney 2, a rain cap is provided above the chimney 2, the top inner wall of the outer cover 3 is in contact with the top of the chimney 2, and the bottom of the outer cover 3 is fixed to the roof connect. The bottom of the outer cover 3 surrounds the outer cover 3 with shutters 1, and the shutters 1 make the inner ...

Embodiment 2

[0036] Such as figure 2 As shown: the difference between embodiment 2 and embodiment 1 is that the heat exchanger 4 has four pieces, and the four heat exchangers 4 are respectively arranged at the four gas outlets near the chimney 2, and are arranged at intervals from the gas outlet of the chimney 2 , to ensure that the gas discharged from the gas outlet of the chimney 2 is heat-exchanged through the heat exchanger 4, and it can also prevent the heat exchanger 4 from obstructing the exhaust of the chimney 2. The height of the heat exchanger 4 is equal to the height of the gas outlet of the chimney 2.

Abstract

The invention discloses a roof heat exchange recovery system, and belongs to the technical field of house ventilation equipment. The roof heat exchange recovery system is characterized by comprising a cover (3) covering a chimney (2), a heat energy exchange device and a water tank (5); the lower part of the cover (3) is communicated with atmosphere; a heat exchanger (4) is arranged in an outlet of the chimney (2); the heat energy exchange device is respectively connected with the heat exchanger (4) and the water tank (5); and gas exhausted by the chimney (2) is discharged from the lower part of the cover (3) after passing through the heat exchanger (4). The cover of the roof heat exchange recovery system enables indoor gas to be exhausted into atmosphere from the bottom of the cover after downwards flowing along the outer wall of the chimney during exhausting, so that the heat exchanger can fully exchange heat with the gas exhausted by the chimney, and the heat energy recovery efficiency is improved; the heat energy exchange device uses the heat energy recovered by the heat exchanger for heating water in the water tank; and when indoor air is exhausted into the atmosphere, the temperature is lowered, and condensed water directly drops down a roof and flows out along the bottom of the cover.

Description

technical field [0001] A roof heat exchange recovery system belongs to the technical field of house ventilation equipment. Background technique [0002] Most of the top of the house is equipped with an exhaust channel to discharge the air in the house, so that the indoor air can be circulated to ensure the freshness of the indoor air. The exhaust channel is generally arranged on the top of the house. In winter, the indoor temperature is generally higher, and the hot air will rise and be discharged to the outside through the exhaust channel, and the fresh air from the outside will enter the room, thereby realizing the circulation of indoor air. The air with a higher temperature in the room is directly exhausted to the atmosphere, which causes a large loss of energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a roof heat exchange recovery system that recovers the...
