Clean purification air-conditioning control method for operating room and application system thereof

Abstract

The invention relates to a clean purification air-conditioning control method for an operating room. The clean purification air-conditioning control method comprises the following steps of: executing the function of air regulation by using an electric adjustable air valve A mounted in a fresh air passage, a frequency-variable fan mounted in a circulating air passage and an electric adjustable air valve B mounted in a discharge air passage, so as to carry out control on the air regulation of the operating room under different working conditions, wherein the control is achieved by comparing operating progress information inputted through a keyboard and the indoor pressure value of the operating room acquired by a pressure sensor mounted in the operating room with data stored in a data storage unit by a processing unit, and calling out preset fresh air volume values and circulating air volume values corresponding to different operating stages according to the compared result to adjust the opening degree of the electric adjustable air valve of the fresh air passage, so as to control air volume; and adjusting a circulating fan frequency converter to execute frequency conversion, so as to control the air volume.

Description

technical field [0001] The invention belongs to a purification and ventilation system, and in particular relates to an intelligent control method and an application system for a purification air conditioner in a clean operating room. Background technique [0002] At present, for hospital buildings, the design of the air-conditioning system adopts the centralized air-conditioning system. Due to the relatively high environmental cleanliness requirements in many departments of the hospital, the ventilation volume of the rooms is several times that of ordinary air-conditioned rooms, especially in high-level clean operating rooms, where the ventilation times range from dozens to hundreds of times per hour. Second-rate. In addition, a high-efficiency air (HEPA) filter will be specially installed at the air outlet end of the clean operating room. Due to the high number of air changes and the considerable flow resistance of the air filter, the energy consumption in the operating r...

Problems solved by technology

In addition, the medical staff and equipment involved in medium-sized and large-scale operations are different, and the load required is also quite different.

However, when designing the air conditioner for the operating room, it is calculated according to the load required by the most unfavorable working state. Therefore, medical staff generally feel cold when entering the operating room during non-operative hours, and the high waste of energy is obvious.

As mentioned above, the design of the hospital air-conditioning system adopts the centralized air-conditioning system, and the operating room is part of the air-conditioning network. Temperature and humidity display, if major adjustments are required, only the power department can be requested to adjust the air conditioning purification ventilation unit
