Background

The total heat exchanger is a fresh air and exhaust air interchanger containing a heat exchange core. The indoor air purifier can exhaust dirty indoor air, suck outdoor fresh air into the indoor space and keep the indoor air clean all the time. The total heat exchanger exchanges heat between indoor dirty air to be exhausted and outdoor fresh air to be sucked in the machine through the heat exchange core body, and heat loss is reduced. Disadvantages/drawbacks of the existing total heat exchangers: (1) the fixing of the shell sheet metal part of the total heat exchanger is realized by using self-tapping screws, and the connection strength of the self-tapping screws can be reduced under the condition that the machine is repeatedly disassembled, so that the function of connecting and fixing the sheet metal part of the machine cannot be realized; (2) the inside multiple filter screen that does not have of total heat exchanger can not filter outdoor new trend and indoor return air, directly inhales outdoor new trend, can't guarantee the cleanness of indoor air. Indoor return air cannot be filtered, indoor dirty air is directly discharged to the outside, a large amount of dust, flock and other suspended matters with large particle size and small particulate matters such as PM2.5 can be accumulated on the heat exchange core in the process of complete exchange, and the service life of the heat exchange core is shortened; (3) for a full heat exchanger installed on a suspended ceiling, a vertically placed heat exchange core body needs to be disassembled, a side plate needs to be disassembled, the disassembling and assembling process is very inconvenient, and the suspended ceiling around a machine is often damaged; (4) the fan in the total heat exchanger is fixed on a machine bottom plate, the fan fails, the fan cannot be directly replaced, the whole machine needs to be replaced, the disassembly and the assembly are difficult, and the suspended ceiling around the machine can be damaged; based on the above problems, we propose a total heat exchanger with a vertically placed heat exchange core.
