Wall-mounted air conditioner with air supply at upper part and air return at lower part

Abstract

The invention provides a wall-mounted air conditioner with air supply at upper part and air return at lower part. The wall-mounted air conditioner comprises an air return port arranged on the lower side of the wall-mounted air conditioner and an air supply port arranged on the upper side of the wall-mounted air conditioner, so that air supply at the upper part and air return at the lower part areachieved; the air supply port adopts multi-leaf double-layer shutter air supply port and is the temperature sensing air port, cold air is automatically adjusted to be blown to the oblique up directionaccording to the temperature through an temperature sensing memory alloy when the air conditioner blows the cold air, and hot air is automatically adjusted to be blown to the oblique down direction according to the temperature through an temperature sensing memory alloy when the air conditioner blows the hot air; a fan is arranged on the upper side of the interior of the wall-mounted air conditioner and is adjacent to an air supply opening, a surface air cooler is arranged on the lower side of the interior of the wall-mounted air conditioner, chilled water or fluorine refrigerant is introduced into the interior of the surface air cooler, and a condensed water discharge outlet is formed in the bottom of the surface air cooler; and the air supply flow temperature of the wall-mounted air conditioner for refrigeration and heating is set to be 12-15 DEG C and 35-40 DEG C respectively, the air supply is blown to more than two meters, the flow rate of mixed air is reduced after the backflowtemperature of mixed air reaches 25-27 DEG C, and the mixed air flows through a personnel staying area.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a wall-mounted air conditioner with air supply from the upper part and return air from the lower part. Background technique [0002] The key technology of the wall-mounted air conditioner is the airflow organization, that is, the air supply outlet and the return air outlet are arranged reasonably in the air-conditioned room, so that the purified and heat-humidified air is sent into the room through the air supply outlet, and in the process of diffusion and mixing, Eliminate indoor waste heat and humidity evenly, so that the working area can form a relatively uniform and stable temperature, humidity, air velocity and cleanliness to meet the requirements of production technology and human comfort. [0003] The air supply mode of an air-conditioned room depends on the source and distribution of heat in the room. According to the characteristics of the room, such as precise ...

AI Technical Summary

Problems solved by technology

This is because the air supply and return methods of the existing wall-mounted air conditioners are all from the lower part and the upper part returns the air. The temperature of the air supply air blown by the air conditioner is generally 12-15°C for cooling, and 35-40°C for heating. The cold air blows out obliquely, and directly blows at high speed to the area below 1.8 meters where people stay. The wind speed is relatively high, which is very uncomfortable. The room The temperature is not uniform, and the temperature of the area directly blown by the air supply is very low, so no one is willing to stay in the front area of ​​the wall-mounted air conditioner. There are even baffles hanging on the wall-mounted air conditioner to block the air outlet on the market to reduce the feeling of blowing

But this will cause a short circuit of the air supply and reduce the efficiency of the air conditioner
