Problems solved by technology

But at the same time, this has caused the energy consumption problem of the building: in winter, the heating and ventilation of the house will cause the loss of indoor heat, which increases the cooling load of the building; load, therefore, the loss of building energy consumption due to the ventilation of the fresh air system cannot be ignored
For this reason, the heat exchanger of the fresh air system has attracted our attention, but the common heat exchangers on the market cannot be well integrated with the building, and there are also disadvantages such as low heat exchange efficiency and unsuitable maintenance.

Embodiment 2

[0035] In one embodiment of the present invention, as figure 2 ,and figure 1 The difference between the two embodiments is that the thickness of the building wall is different. When the thickness of the wall is not enough to support the heat utilization unit, the heat utilization unit is arranged outdoors; and the outdoor ventilation channel is arranged vertically.

[0036] In an embodiment of the present invention, the fan 4 is only installed on the indoor side of the exhaust flow channel 3, and the indoor and outdoor gas exchange is realized through the forward and reverse adjustment of the fan.

Embodiment 3

[0038] In one embodiment of the present invention, as image 3 shown, with figure 1 The difference of the middle embodiment is that the heat pipe 8 is not provided inside, and the process of rapid heat storage and heat release is realized only through the foam metal heat storage body 7 as a heat material; the solid arrow in the figure is the flow direction of the air when the fan 4 is normally turned on. ; After a certain period of time, the foam metal heat storage body 7 stores the heat of the hot air, makes the motor 7 reverse, and transfers it from the heat recovery unit to the heat release unit, so as to realize the heat recovery of the fresh air, effectively reduce the heat loss, and realize the The heat energy recovery and utilization of indoor exhaust air can effectively reduce building energy consumption.

Embodiment 4

[0040] In one embodiment of the present invention, as Figure 4 shown, with figure 1 The difference of the embodiment in the middle is that the heating material is the tube bundle 9, and the tube liquid inside is water; the solid arrow in the figure is the flow direction of the air when the fan 4 is normally turned on; after a certain time, the heat release unit and the heat recovery unit The temperature of the inner tube bundle 9 tends to be stable, and the fan 4 is reversed, so that the air flow direction in the exhaust flow channel 3 is opposite. At this time, the temperature of the tube bundle 9 changes, and heat energy recovery is performed, and the air flow direction is shown as a dotted arrow; After the temperature of 9 stabilizes again, switch the direction of the fan again.

[0041] In an embodiment of the present invention, the foamed metal material is selected from foamed steel or foamed aluminum; the heat pipe is selected from hot copper or stainless steel heat pi...

Abstract

The invention discloses a breathing type building fresh air energy instant storage and exchange device which comprises an air exchange channel installed in a wall. The ventilation channel communicates indoor and outdoor; the ventilation channel comprises a fresh air flow channel and an exhaust flow channel which are mutually coupled; a fan is mounted on the inner side of the exhaust runner chamber; and the heat utilization unit is arranged in the ventilation channel and communicates the fresh air flow channel with the exhaust flow channel. The heat utilization unit is arranged in the wall body, so that the problem that a fresh air system in a building cannot well utilize heat and cold is solved; fresh air backheating can be achieved, heat loss is effectively reduced, heat energy recycling of indoor exhaust air is achieved, and building energy consumption is effectively reduced.

Description

technical field [0001] The invention relates to the cross-technology field of thermal energy engineering technology and building energy saving, in particular to a breathing type building fresh air energy instant storage and exchange device. Background technique [0002] People spend most of their lives in buildings, and maintaining good indoor air quality in buildings has a crucial impact on people's health and high quality of life. As a common method, ventilation can introduce outside air to maintain the quality of the air inside the building. For this reason, the minimum fresh air volume of the building is required at home and abroad. It is clearly required in my country's regulations that the minimum fresh air volume per capita in the office is 30m2 / h. As a common ventilation and ventilation device, the fresh air system is widely used by people. But at the same time, this also leads to the problem of energy consumption of the building: in winter, the indoor heating and ...
