Problems solved by technology
The quality of the total heat exchange core determines the exchange efficiency and service life of the fresh air fan. When the indoor and outdoor temperature difference is large, condensation and serious frost will occur in the fresh air channel and exhaust air channel of the fresh air machine. Prevent the full heat exchange core from performing full heat exchange, affecting the use of fresh air fans

The invention relates to a fresh air system and an operation method. The fresh air system comprises a shell, wherein the shell is internally provided with a heat exchange core and a control unit, and the shell is provided with an outdoor air inlet, an indoor air inlet, an indoor air outlet and an outdoor air outlet. The fresh air system has a first working mode; and the control unit is configured to enable the fresh air system to be in the first working mode, so that after air of the indoor air outlet passes through the heat exchange core, one part of the air is exhausted outdoors through the outdoor air outlet, and the other part of the air is mixed with air of the outdoor air inlet, passes through the heat exchange core and then enters a room through the indoor air inlet. After indoor air flows through the heat exchange core, one part of the air is mixed with fresh air introduced from the outdoor air inlet, the temperature of the fresh air can be increased, the mixed air flows through the heat exchange core again, the heat exchange efficiency of the heat exchange core can be improved, heat loss is reduced, condensation is prevented, meanwhile, humidity and heat in the heat exchange core are blown into the room, and the indoor comfort is improved.
Description
technical field [0001] The invention relates to the field of air conditioning, in particular to a fresh air system and an operation method. Background technique [0002] For fresh air fans with full heat exchange function, the realization of full heat exchange function depends on the full heat exchange core inside the fresh air machine. The quality of the total heat exchange core determines the exchange efficiency and service life of the fresh air fan. When the indoor and outdoor temperature difference is large, condensation and serious frost will occur in the fresh air channel and exhaust air channel of the fresh air machine. Prevent the full heat exchange core from performing full heat exchange, affecting the use of fresh air fans. Contents of the invention [0003] Some embodiments of the present invention provide a fresh air system and an operation method for alleviating the condensation problem. [0004] In one aspect of the present invention, a fresh air system is ...
