The invention discloses an air conditioning system for an underground space and a control method of the air conditioning system. The control method specifically includes processes that a first temperature value T1, a second temperature value T2, second temperature control accuracy T3 and a carbon dioxide concentration normal valve C1 are set in a control device in advance; a first temperature sensor, a first humidity sensor, a second temperature sensor and a second humidity sensor separately feed back the detection result to the control device; the control device calculates and compares a fresh air enthalpy value with a return air enthalpy value, if the fresh air enthalpy value is greater than the return air enthalpy value, a cooling and dehumidifying mode of the air conditioning system isturned on, otherwise, a ventilation mode of the air conditioning system is turned on; and when the air conditioning system is in the ventilation mode, if an actual return air temperature valve is less than T2, a heating mode un the air conditioning system is turned on. The control method of the air conditioning system for the underground space can adjust the working state of a fresh air unit anda return air unit according to the comparison result between an outdoor enthalpy value and an indoor enthalpy value, and the energy consumption of the air conditioning system is reduced while air quality is ensured.
Description
technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to an air conditioning system for an underground space and a control method thereof. Background technique [0002] The underground space is a confined space, and there is a large amount of personnel activities. Therefore, the underground space has the problems of high air humidity and high indoor carbon dioxide concentration. [0003] Due to the special environment of the underground space, it is necessary to adjust the working status of the air conditioning system in the underground space in different seasons; in summer, the air conditioning system needs to dehumidify and cool the underground space; in transitional seasons, the air conditioning system needs to Keep the underground space ventilated; in winter, the air conditioning system needs to keep the underground space ventilated and ensure that the temperature of the underground space will not be too low.
