Energy-saving type management controller for clean operation room purifying air-conditioning system

Abstract

The invention discloses an energy-saving type management controller for a clean operation room purifying air-conditioning system. The controller body is connected with a fresh air regulating valve, afresh air processing unit, a purifying air conditioning unit, an air supply regulating valve, a return air regulating valve and an exhaust fan of an operation room correspondingly. The controller bodyhas functions of direct starting up, appointed starting up and temperature and humidity setting. The actual value monitored by a temperature-humidity sensor and the set value can be utilized to makea comparison, and the opening degree of cold and heat source electrical valves of the fresh air processing unit and the purifying air conditioning unit is controlled. The controller body is equipped with a power-off self-purification function, direct self-purification or preset self-purification can be selected, and corresponding self-purification time is set. Besides, the controller body is further connected with a carbon dioxide sensor by which the carbon dioxide concentration inside the operation room can be monitored; and only when the self-purification time is out and the carbon dioxide concentration reaches the standard, purification air conditioning equipment related to the operation room stops running. By means of the energy-saving type management controller for the clean operationroom purifying air-conditioning system, accurate control over the air purification processing process of the operation room in stages such as a pre-operation stage, a post-operation stage and a during-operation stage can be achieved; and in addition, energy can be saved greatly.

Description

technical field [0001] The invention belongs to the technical field of purification and air-conditioning system management, and relates to an energy-saving management controller for a purification and air-conditioning system in a clean operating room, so as to realize precise control of the air purification process in the pre-operative, post-operative and inter-operative stages of the operating room. Background technique [0002] At present, energy saving, emission reduction and green development are the basic national policies of my country's social and economic development. The energy consumption per unit area of ​​hospital buildings is very huge, which is 1.6 to 2.0 times that of other ordinary public buildings. The energy consumption of air conditioners accounts for about 50% of the total energy consumption of hospitals. The clean operation department of the hospital has very special air environment treatment process requirements, and the energy consumed accounts for about...

AI Technical Summary

Problems solved by technology

At work, when a certain operation is over, the exhausted medical staff begin to evacuate the operating room, because the air in the operating room needs to be self-cleaned for a period of time to remove pollutants (see Table 1 for the minimum self-cleaning time between operating rooms of different levels), so the medical staff cannot Immediately turn off the purification air conditioning system and let it run to purify the air inside the operating room. The nurse on duty in the operating room will patrol, but because the end time of each operation and the self-purification time required for each level of operation are different, the nurse on duty will There is no precise grasp of how much time each operating room has spent on self-cleaning, and few people will tell them how long they need to self-clean (only know that the longer the self-cleaning operation time is, the safer it is), especially in large and medium-sized hospitals with a large number of operating rooms, the on-duty personnel are more It is difficult to identify and operate, so the final shutdown of the equipment usually waits until the off-duty inspection time (that is, the normal off-duty time of the hospital) or the second round of inspection time at night (such as 20:00), resulting in a large amount of running time being wasted ineffectively. There is a serious waste phenomenon: Many nurses on duty in the operating room forget to turn on the operating room in order to avoid the rush in the morning. They will immediately turn on the air-conditioning equipment in the operating room after getting up in the morning (such as 7:00), and wait for the doctor to change at 8:30. Under normal circumstances, self-purification before and during surgery is important for air quality (except CO 2 The treatment requirements are the same, obviously, before the operation, a lot of high-quality air did not play an effective role, but was discharged randomly
