Example

[0028] First embodiment

[0029] See Figure 1-Figure 8 , The total heat exchanger includes an indoor air inlet 2, an indoor fresh air outlet 3, and an outdoor fresh air inlet 4 and an outdoor air exhaust arranged on the rear side of the housing 1 corresponding to each other. For the air port 5, the casing 1 is provided with partitions 9 corresponding to two air inlets and two exhaust ports, and divides the inside of the casing 1 into left and right heat exchange chambers 6 and exhaust chambers 7.

[0030] The heat exchange cavity 6 communicates with the indoor air inlet 2 and the outdoor fresh air inlet 4 respectively. The heat exchange cavity 6 is provided with a heat exchange core 8 which is a set of heat exchange cores, the size of which is the same as that of the heat exchange cavity. The size matches. The side of the heat exchange core 8 corresponding to the exhaust cavity 7 is provided with an acute-angled air outlet surface. The above shape can effectively increase the air...

Example

[0033] Second embodiment

[0034] See Figure 9-14 The main difference between this total heat exchanger and the first embodiment is that the heat exchange cores 8 are in three groups, and the size of each group is about one third of the size of the heat exchange cavity. One side of the heat exchange core 8 corresponding to the exhaust cavity 7 is provided with a vertical air outlet surface. According to actual needs, it can also be designed as an inclined air outlet surface, or an arc-shaped air outlet surface, or other shapes of air outlet. The main purpose is to increase the air outlet area of ​​the heat exchange core 8, which can increase the air output and reduce the working noise of the equipment.

[0035] The partition 9 of this embodiment is divided into four layers from top to bottom. The upper and lower partitions 9 are respectively connected to the top and bottom of the heat exchange core 8, and the partitions 9 of the middle two layers are vertical to the heat exchange...

Abstract

The invention relates to a total heat exchanger which comprises an indoor air inlet, an indoor fresh air outlet arranged at the front side of the housing, and an outdoor fresh air inlet and an outdoor air outlet arranged at the back side of the housing in the mode of correspondence with each other; and the housing is provided with a separating plate corresponding to the two air inlets and two air outlets, such that the interior of the housing is divided into a left heat exchange cavity and a right air exhaust cavity. The heat exchange cavity is communicated with the indoor air inlet and the outdoor fresh air inlet respectively; and the heat exchange cavity is internally provided with one or more groups of heat exchange cores. The side of the heat exchange cores corresponding to the air exhaust cavity is provided with a vertical or oblique air effluent face or an acute-angle-shaped or circular-arc-shaped air effluent face. The separating plate is at least divided into three layers of upper, medium and lower layers, and an air vent is formed between each layer of the separating plate, such that the heat exchange cavity and the air exhaust cavity are communicated with each other. The total heat exchanger provided by the invention has the characteristics of simple design, rational structure, good heat exchange effect, high air interchange efficiency, low noises and the like.

Description

technical field [0001] The invention relates to a total heat exchanger. Background technique [0002] When people are in a closed space, due to the need for breathing, the carbon dioxide content in the air gradually increases, which will affect the health of the human body in severe cases. Therefore, in offices or workshops where many people stay, it should be necessary to replace the polluted indoor air with fresh outdoor air at any time. The most commonly used method is to use a ventilation fan to ventilate the room, but when the ventilation fan is used to exhaust the indoor air to the outside, the air that has been cooled or heated by the air conditioner and other equipment in the room will also be exhausted to the outside without reservation, which greatly affects the environment. The cooling or heating effect of air conditioners and other equipment increases the power consumption of air conditioners and other equipment. [0003] Chinese Patent Document No. CN201407776...
