Abstract
The invention discloses a self-adaptive heat balance system for a machine station. The self-adaptive heat balance system comprises a heat exchange core, a control module and a temperature collection unit. An outer circulation duct gap is formed between the heat exchange core and a cabinet body. The upper portion and the lower portion of the cabinet body are provided with an outer circulating fan and an inner circulating fan respectively. At least two movable air doors which are controlled by the control module to act are arranged on the periphery of the outer circulating fan and on the periphery of the inner circulating fan. The control module controls the corresponding movable air doors to act according to the change of indoor temperature and outdoor temperature, and automatic switching of heat exchange heat dissipation or fresh air heat dissipation or fresh air heat change heat dissipation is achieved. Part of outdoor air passing through the heat exchange core is made to enter a room through the outer circulating fan. Due to the fact that the heat balance system is controlled to be in a heat exchange heat dissipation state or a fresh air heat dissipation state or a fresh air heat exchange heat dissipation state according to the indoor temperature and the outdoor temperature, an outdoor cold source is utilized reasonably, and energy is saved. Meanwhile, when the heat balance system is in a fresh air state, the outdoor air is preheated and then enters the room, and the phenomena of indoor rime and condensation are reduced.
