Air conditioners are designed and produced in different types based on the type of use, air flow control, zoning, blower fan placement, air output capacity, etc., but the most important types are divided into industrial and domestic. Structurally, there is no difference between these devices, and only their dimensions, the type of filters used, whether or not they are equipped with dehumidifiers and dehumidifiers, and the percentage of air returned to the devices are different. In the rest of this article, we will examine the electricity consumption of the home air conditioner.
Performance of household er electricity consumption
The basis of the work of a home air conditioner is to provide optimal air in terms of temperature, humidity and free of polluting particles in the space of residential and office buildings. The performance of these air conditioners is such that they pass the air through the cooling and heating coils and after adjusting the air temperature, if necessary, they also adjust the humidity level of the air using humidifiers. They also absorb pollutants in the air by means of different filters.
In home air conditioners, like other equipment, energy consumption is very important. Low-consumption air conditioners are more popular among customers, and for this reason, companies producing such equipment should consider this issue.
In the winter season, electricity consumption in home air conditioners is not significant because the heat is usually produced by hot water or gas and transferred to the home air conditioner. But in the summer season, evaporative air conditioners create cooling independently, which naturally require more electricity consumption.
The electricity consumption of evaporative air conditioners (airwashers) for a residential or office apartment unit with an approximate area of 150 square meters in Tehran conditions is almost equivalent to the electricity consumption of water coolers of the same capacity. Because they only have a 1/2 or 3/4 horse electric motor (about 400 watts) along with a small water pump. But the power consumption of cooling air conditioners with DX coils is much higher (about 3000 to 4000 watts) than water coolers or air washers due to having a compressor.
Thermal recovery and reduction of electricity consumption in home air conditioners
In general, the higher the efficiency of the device, the lower the electricity consumption of the air conditioner. One of the ways to increase the efficiency of home air conditioners is heat recovery, which mixes the fresh air flow entering the device and the air flow coming out of it. By using this method, the thermal requirements of the air conditioner are reduced and the dimensions of the system and its energy consumption are also saved.
Using a thermostat and effectively reducing the electricity consumption of household air conditioners
A thermostat is a device that optimizes the air conditioner's electricity consumption. In this way, the desired temperature is set by it and the air conditioner's operation rate is controlled. In this way, the device will not work permanently and this will reduce electricity consumption.
Controlling the power consumption of the air conditioner through the inverter
Starting the air conditioners through the inverter makes it possible that the device starts working at a variable speed and after reaching the predetermined temperature by the temperature sensor around the electric motor, it changes. In this way, the temperature of the halls is maintained and the ventilation efficiency of the device can be controlled. This item reduces the power consumption of the device.
The effect of filters on the electricity consumption of home air conditioners
The cleanliness of secondary filters or bag filters will play a very important role in the proper functioning of home air conditioners. Clean bag filters have very soft and flexible materials, and this feature allows them to absorb many particles on them. If the bag filters are dirty, it will be more difficult for them to work because of the resistance to the flow of air movement. This means that the filter must withstand more pressure, in which case the device will consume more energy. did Therefore, in order to reduce the electricity consumption of the home air conditioner, you should be sure that these filters are clean.
Electricity consumption in home air conditioners with evaporative and DX systems
In air conditioners with direct expansion coils or DX (abbreviation for Direct Expansion) that work based on the compression refrigeration cycle, water fluid is not used as a medium for heat transfer, and the refrigerant directly cools and heats the air. to give Therefore, they are called fan coils or air conditioners with direct expansion coils or air conditioners with DX coils. This type of air conditioners, unlike air conditioners based on the evaporation system, use a compressor for cooling. Therefore, the electricity consumption of air conditioners with direct expansion (refrigeration) coils is higher than evaporative air conditioners.
