Central air conditioning system achieving combination of ordinary time and epidemic period

Abstract

The invention discloses a central air conditioning system achieving the combination of the ordinary time and the epidemic period. The central air conditioning system comprises a purification treatmentunit, an air handing unit and a ventilation fan. An air inlet of the purification treatment unit is connected with an air outlet and a first fresh air pipeline of a working region through a pipelineand an inlet valve, an air outlet of the purification treatment unit is connected with an air inlet of the working region through a pipeline, an outlet valve, the air handling unit and the ventilationfan in sequence, and the inlet valve of the purification treatment unit is connected with the outlet valve of the purification treatment unit through a pipeline and a first valve. An air inlet of theair handing unit is connected with an air outlet of the air handling unit through a pipeline and a third valve. The central air conditioning system can be flexibly switched to run at the ordinary time and the epidemic period, operation of a central air conditioner at the four modes of the ordinary time, the epidemic situation, the disinfection and the fresh air can be achieved through the adjustment of opening and closing operation of the valves arranged in the system, purification of the air and elimination of viruses can be conducted in the epidemic period, the excessive energy consumptioncannot be increased, and the appropriate office environment in a building is guaranteed.

Description

technical field [0001] The invention relates to the technical field of building heating and ventilation, in particular to a central air-conditioning system combining epidemic prevention and control. Background technique [0002] The operation of the central air-conditioning system has the possibility of accelerating the spread and spread of the virus, and increasing the risk of cross-infection among people in different areas of the building. In order to curb the spread of the epidemic, the use of central air conditioners generally adopts (1) fresh air operation and (2) prohibition of use. However, as most parts of our country are about to enter the hot summer, neither of the two solutions can effectively solve the problem in summer. Indoor office environment issues. Therefore, it is particularly important to design a central air-conditioning system that can be used normally and has low energy consumption during normal times and epidemics.
