What is the working principle of air-cooled air conditioners and what are the selection techniques

In recent years, the development of the air-conditioning industry has made some relatively new technologies gradually applied to these aspects. Even in the dry autumn or cold winter, the air conditioner still plays an important role, and its appearance is no longer so simple. Then, only after we understand some basic knowledge of air conditioners, can we correctly choose the type of air conditioner that is more suitable for us when purchasing. So, what is the working principle of air-cooled air conditioners and what are the selection techniques?

　　How does the air-cooled air conditioner work?

First, the compressor compresses the refrigerant into a liquid, and then transports it to the evaporator. The liquid volatilizes into a gas and then takes away the heat. The evaporator cools down, and the circulating water is cooled. The room can realize a relatively fast heat and cold exchange through a fan, which reduces the indoor temperature.

　　What are the selection techniques?

　　 1. Look at the amount of cooling (heat) of the air conditioner: the amount of heat generated from a confined space per unit time when the air conditioner is operating, the legal unit of measurement is W (watts). The actual cooling (heat) capacity of the relevant air conditioner specified by the national standard shall not be less than 95% of the rated cooling (heat) capacity. This key indicator of the air conditioner must be clearly seen when purchasing.

　　2. Look at the noise value of the air conditioner: refers to the noise generated when the air conditioner is running, mainly produced by the internal evaporator and the external condenser. According to national regulations, the noise of indoor unit of air conditioner with cooling capacity below 2000W shall not exceed 45 decibels, and the noise of outdoor unit shall not exceed 55 decibels; the noise of indoor unit of split air conditioner of 2500W～4500W shall not exceed 48 decibels and the outdoor unit shall not exceed 58 decibels. When purchasing, it depends on whether the noise level of the product meets the standard, and the noise value is smaller.

　　3. Choose a good air conditioner brand: There are many air conditioner brands on the market now, domestic and foreign, and most of them have their own unique advertising, making it difficult for consumers to choose. It is recommended that when purchasing air conditioners, choose those products with strong corporate strength and perfect after-sales service.

　　4. Consider the structure of the air conditioner: Before purchasing an air conditioner, you need to choose a suitable air conditioner structure according to the placement space. If you choose a window type or a hanging type, you need to combine the characteristics of different structure air conditioners and the situation of the room to choose.

　　5. Consider the situation of the air-conditioned room: The situation of the air-conditioned room should be considered in advance when purchasing an air conditioner. According to the degree of heat preservation of the room, the floor, the height of the room, the decoration of the room, the size of the glass window, the heat dissipation of the equipment in the room, the high brand awareness of personnel activities, etc., the size of the air conditioner should be considered appropriately. In the morning, the ventilation is not good. The room should appropriately increase the power of the machine. Normally, 110W to 220W of cooling heat per square meter is more appropriate.

In the above content, the author has made a more detailed introduction of some aspects of knowledge from the working principle of air-cooled air conditioners and the selection techniques of air conditioners. I hope that from these contents, you can obtain some more useful information. .
