Air Cooler
Air Cooler Introduction
The equipment includes condensing unit, main control board, temperature control board of cold chamber, operating board, etc.
Optional cold chamber temperature control panel and operating panel.The main control board can start/stop the compressor through.
the system low pressure, suitable for supermarkets, milk containers, chiller, etc., optional, the system can control the compressor through the temperature, with temperature adjustment, defrosting adjustment functions.
Air Cooler Advantages
The whole control system can be used directly in the cold room without the need for additional controllers.It has a variety of protection functions, such as phase retaining, phase missing, overcurrent, compressor starting overstability, exhaust temperature, high/low temperature of the system, etc.With fan speed regulator, the condensing fan can be adjusted according to the condensing temperature.With operation data display function, it can check the running current, exhaust temperature and condensing temperature of compressor.
Product suitable to the latest refrigerant such as R410A, CO2, ammonia, glycol and other special refrigerants are available.
pressure, suitable for supermarkets, milk containers, chiller, etc., optional, the system can control the compressor through the temperature, with temperature adjustment, defrosting adjustment functions.
Operating Principle
The cooling principle of the air cooler (evaporative air conditioner) is: when the fan is running, it enters into the cavity to generate negative pressure, so that the outside air flows through the porous and humid curtain surface to force the dry bulb temperature of the curtain air to be close to the outside air The wet bulb temperature, that is, the dry bulb temperature at the outlet of the air cooler is 5-12°C lower than the outdoor dry bulb temperature (up to 15°C in dry and hot areas). The hotter the air, the greater the temperature difference, and the better the cooling effect. Because the air is always introduced indoors from outside, (this time is called a positive pressure system), it can keep the indoor air fresh; at the same time, because the machine uses the principle of evaporation and cooling, it has the dual functions of cooling and humidification (relative humidity can reach 75% It can not only improve the cooling and humidification conditions, but also purify the air, reduce the needle breakage rate in the knitting process, and improve the quality of knitting textile products.
The air cooler (evaporative air conditioner) is surrounded by a honeycomb wet curtain made of special materials, which has a large surface area and continuously humidifies the wet curtain through the water circulation system; the wet curtain air cooler is equipped with a high-efficiency, low-noise and energy-saving fan. When the fan is running, the negative pressure generated by the wet curtain air cooler causes the air outside the machine to flow through the porous and humid wet curtain into the machine. The evaporation of water on the wet curtain absorbs heat, forcing the air passing through the wet curtain to cool down. At the same time, since the water on the wet curtain evaporates to the air flowing through the wet curtain, which increases the humidity of the air, the wet curtain air cooler has the dual function of cooling and increasing humidity.
Main features of air cooler
①Low investment and high efficiency (probably only 1/8 of the power consumption of traditional central air-conditioning) ②The air cooler can be used without closing the doors and windows. ③It can replace the turbid, hot and odorous air indoors and exhaust it outside. ④Low power consumption, electricity consumption per hour is 1.1 degrees per hour, without Freon. ⑤The air supply volume of each air cooler depends on the choice: 6000-80000 cubic meters. ⑥Each cold wind covers an area of 100-130 square meters. ⑦ Cooling main part (wet curtain).
