The invention discloses an
air conditioning system for a
cardiac surgery operating room and a control method of the
air conditioning system, relates to the technical field of air conditioners, and solves the problem that a direct expansion
air conditioning system in the prior art needs to be
shut down for
defrosting in winter. The air conditioning system comprises a cold and heat source
assembly and a combined air conditioning unit, the cold and heat source
assembly at least comprises a first cold and heat source and a second cold and heat source, the combined air conditioning unit at least comprises a first direct expansion coil
pipe and a second direct expansion coil
pipe, the first cold and heat source is connected with the first direct expansion coil
pipe, and the second cold and heat source is connected with the second direct expansion coil pipe. And based on the
operation mode and the operation working condition of the air conditioning system, at least one of the first cold and heat source and the second cold and heat source is in the operation state, meanwhile, at least one of the first direct expansion coil and the second direct expansion coil is in the operation state, and air passing through the combined air conditioning unit is fed into a room after reaching the preset temperature and the preset
humidity. In winter, the two cold and heat sources of the air-conditioning system are alternately used, and the stability of the temperature and
humidity of the operating room can be maintained.
