Problems solved by technology

In winter when the outdoor ambient temperature is too low and the temperature difference between the indoor and outdoor environments is too large, the total heat exchanger in the prior art chooses not to open or continue to operate. If the total heat exchanger is not opened, the total heat exchanger recovers heat again. The function cannot be realized, and the indoor temperature is low. If the total heat exchanger continues to operate, because the outdoor ambient temperature is too low or the temperature difference between indoor and outdoor is large, after the outdoor fresh air and the indoor return air exchange heat in the total heat exchanger, After the outdoor fresh air gets heat, the temperature is still low. After the outdoor fresh air enters the room, the indoor temperature drops and cannot reach the expected temperature.

Abstract

The invention relates to the technical field of ventilating systems and discloses a total heat exchanger and a control device and method thereof in order to solve the problem that an existing total heat exchanger cannot give consideration to all the changes of spring, summer, autumn and winter (including severe cold weather). The total heat exchanger comprises a box body. The box body is provided with an outdoor air inlet, an indoor air supply outlet, an indoor return air inlet and an outdoor air outlet. A heat exchange core body, an air supply fan and an exhaust fan are arranged in the box body. The box body is further internally provided with a first heat exchange air channel, a second heat exchange air channel, a bypass air channel and an internal circulation air channel. The total heat exchanger can conduct switching among a heat exchange mode, a bypass mode and an internal circulation mode. The total heat exchanger is used for an indoor ventilation system.

Description

technical field [0001] The invention relates to the technical field of ventilation systems, in particular to a total heat exchanger, a control device and a control method thereof. Background technique [0002] The total heat exchanger is a high-efficiency and energy-saving air-conditioning and ventilation device. It uses the temperature difference between indoor and outdoor air to exchange heat through the heat exchange core, so that the indoor and outdoor air can exchange heat while ventilating in two directions. The outdoor fresh air , can obtain heat or cooling from the indoor return air discharged from the room, so that the indoor temperature fluctuation is small, and save the energy consumption of the outdoor fresh air pretreatment, realize energy saving and environmental protection, therefore, more and more people pay attention to it. [0003] The total heat exchanger in the prior art cannot take into account the changes in the temperature difference between indoor and...
