When the filter infarction or when it is beyond the rules of value, the pressure switch gives the switch signal. When demand for cooling, the cooling thermostat placed in the form, when the temperature sensor is at or below the set temperature, the thermostat to the electric valve a signal off valve, close the valve contacts the valve closed motor valve is turned on . If the measured temperature does not reach the set temperature, the thermostat to the electric valve a signal to open the valve, the electric valve open contact to put the valve open. Demand heating, the heating thermostat placed in the form of air conditioning units brand, when the temperature sensor reaches or higher than the set temperature, the thermostat to the electric valve a signal off valve, close the valve electric valve contact to put the valve closed. If the measured temperature does not reach the set temperature, the thermostat to the electric valve a signal to open the valve, the electric valve open contact to put the valve open. Cooler segment: Table cold pipe surface wind speed ≤2.5m / s, and a hydrophilic membrane flat fins make air-conditioning unit price, the heat exchange efficiency is good and easy to dust Zi bacteria wucheng air conditioning units, will not produce the phenomenon with water ; heating section: to use hot water heating, steam heating, electric heating; electric heating stainless steel optical tube production, smooth surface without fins, corrosion resistance, easy to fouling, easy to clean; humidification section: can be dry or wet steam electrode humidifying air conditioning unit, make sure that no water inside the humidifier after the shutdown, the possibility of the humidifier to eliminate bacterial growth; sterilization of: You can use ultraviolet light or ozone sterilization generator, completely destroyed the living environment of the bacteria inside the unit; air conditioning Units Brand | Chenyu air conditioning (certified) | air conditioning unit provided by Wu Cheng Chen-yu air-conditioning Limited. Wu Cheng Chen-yu air-conditioning Co. (www.wccykt.com) is an industry leader in Shandong Dezhou, fans, ventilation equipment, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs . Chen Yu-conditioned in leadership with the staff warmly welcome all inquiries negotiations to create Chenyu air conditioning better future.
