Air conditioning system for cardiac surgery operating room and control method of air conditioning system

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning system used in a heart surgery operating room and a control method thereof. Background technique [0002] At present, cardiovascular disease has become the number one chronic disease with high mortality, high disability rate and high medical expenses, including coronary heart disease, hypertension, heart failure, etc. The current treatment methods for cardiovascular diseases include coronary interventional stents and surgical bypass surgery, and there will be more and more demands for operating rooms capable of performing cardiac surgery. [0003] According to the actual needs of medical treatment, it is necessary to establish an extracorporeal circulation for the patient during cardiac surgery, so that the extracorporeal circulation pump can be used to temporarily replace the heart function during the operation. In the process of establishing extrac...
