Description
Technical field
The utility model relates to air-conditioning technical field, be specifically related to air-conditioner set temperature and humidity control system.
Background technology
Air in environment can be passed through the process of the series of process processes such as heating, refrigeration, noise reduction, and the equipment reaching the temperature and humidity of technological requirement is called air-conditioner set; Humidity: the ratio of the moisture that can comprise in saturated air at the amount of the moisture comprised in humid air and this temperature; Enthalpy: the enthalpy that enthalpy of humid air is unit quality dry air and its enthalpy sum with Hkg water vapour, its content with water vapour in humid air is relevant with the current temperature of humid air.Water capacity: the water yield comprised in humid air, also referred to as absolute humidity; Psychrometric chart: the relation between the temperature of humid air under different conditions, relative humidity, water capacity and enthalpy is carried out representing with figure line be called psychrometric chart.Air-conditioner set, in Temperature and Humidity Control process, can not reach temperature the short time and control, or temperature controlled precision can not meet process requirements.
The lean of producing and the hommization of operating personnel's working environment improve, and technique air supply air-conditioner unit also controls from initial cardinal temperature, brings up to the accurate control of temperature, humidity;
Common air-conditioning temperature and humidity control system, the air-conditioner set pattern controlled by cardinal temperature in the past improves; Namely simple judgement is compared to wind pushing temperature, humidity and air feeding technique temperature, humidity, then regulate the size of the hot and cold water yield to reach technological requirement;
When temperature is low, improve the input of hot water amount, temperature height then reduces the input of hot water amount;
When humidity height then improves the input of cool water quantity, humidity is low, reduces the input of cool water quantity; Or regulate the size of shower humidification pump frequency;
Adopt conventional air-conditioner control system, can only, simply by difference reduced temperature and humidity, regulate cold water, hot water amount or shower humidification amount to reach technological requirement respectively;
As: when ambient temperature is 5 DEG C, when humidity is 80%, traditional control method: temperature is low needs increase hot water amount to improve temperature, humidity then needs to increase cool water quantity higher than technique humidity and reduces humidity, and shows from psychrometric chart and to need first to heat rear shower humidification under this kind of ambient conditions and increase humidity; Antipodal humidity regulation;
And for example: ambient temperature is 30 DEG C, when humidity is 55%, traditional control method: temperature is high needs minimizing hot water amount to reduce temperature, and humidity is lower than technique humidity requirement or the spray flux improving spray pump; And show from psychrometric chart and to need first to show cold rear shower humidification under this kind of ambient conditions and increase humidity; Now there is the situation of contradiction in traditional control method in the selection of process function section;
Adopt conventional control device in the above cases, need through constantly regulating (actual measurement ordinary circumstance is greater than more than 40min, and special weather reaches 90min) can reach process warm humidity requirement for a long time, energy waste is huge, and control accuracy is not high.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of air-conditioner set temperature and humidity control system, by setting different control models, reach and allow rapidly unit automatically select corresponding control program, reach the temperature of technological requirement with the fastest speed, reduce and adjust for a long time.
To achieve these goals, the utility model realizes by the following technical solutions: air-conditioner set temperature and humidity control system, comprise air conditioner main body, air intlet, temperature sensor and PLC, air conditioner main body is provided with air intlet, air intlet place is provided with temperature sensor, temperature sensor is connected with PLC, and the combustor of PLC and air-conditioning, frequency converter, chilled water control valve, hot water governor valve control are connected.
The utility model is provided with Temperature Humidity Sensor in import of air conditioner, send the air condition of import to PLC, judge that air intake operating mode is now that operating mode by PLC: winter, transition season, summer, then air is regulated by different technique according to different operating modes.
The utility model, by covering the Region dividing of all environmental working conditions, under the design of zones of different environmental model, thoroughly realizes the automatic control of air-conditioning humiture, ensures the optimization of controllability path simultaneously; Thus reach the short time (within 20-30min), reach the accurate control of air-conditioning humiture; The energy consumption of decreased average air-conditioner set about 30min free-runing operation, ensures the production line working time simultaneously.
