Abstract

The invention discloses an air-conditioning unit for a large-bay operating room and a control method thereof. The air-conditioning unit comprises an air supply unit, an air return unit and an optionalfresh air unit. The installation is convenient, the arrangement is flexible, and a technical interlayer does not need to be used as a machine room; on the premise of keeping the total air supply amount unchanged, the fresh air amount is changed, the pressure difference is maintained, the energy consumption is reduced, and the air quality in the operating room is improved; a PLC control system controls the optimum operation of the air supply unit, the air return unit and the optional fresh air unit in real time aiming at the indoor and outdoor changing hot and wet load to form the air conditioning unit, wherein the project quality of the air conditioning unit is completely controlled by a factory; and a traditional purification air conditioning system combined by fresh air centralized treatment and each operating room circulating unit, and a complex air treatment mode are changed, through variable frequency, the total air supply amount and the total air return amount can be changed, the cleanliness level of operating areas can be changed, or air is only supplied to the operating areas needing to be subjected to surgery, or the emergency conversion is a direct current air supply negative pressure mode, and the control requirements of different surgical environments are achieved with low energy consumption.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an air conditioning unit used in a large-bay operating room and a control method thereof. Background technique [0002] The large bay operating room with multiple operating areas stems from Sir John Charnley's pioneering approach to artificial total knee and total hip joints and their replacement surgery, and to optimize the surgical process. By the 1990s, total hip or knee replacement surgery had been perfected, but the demand for hip or knee replacement surgery was too high, resulting in a shortage of experienced senior surgeons and anesthesiologists. For this reason, in 1991, the Robert Jones & Agnes Hunt Orthopedic Hospital (Robert Jones & Agnes Hunt Orthopedic Hospital) in Oswestry, Shropshire, England built the first large bay with 4 operating areas Operating room (Barn Operating Theater, hereinafter referred to as large operating room). There are 4 operating are...
