Low-cost comfortable air conditioner

Abstract

The invention relates to a low-cost comfortable air conditioner. The low-cost comfortable air conditioner comprises a compressor (3), a condensation core (4), a pressure sensor (5), a condensation fan(6), a liquid storage dryer (7), an expansion valve (8), an evaporation core (9), an evaporation fan (10), a temperature sensor (11), an infrared signal receiver (12) and a control unit (13), and also comprises an infrared remote controller I (2) with a built-in temperature-humidity sensor (1). Compared with a conventional infrared remote controller III (16), the infrared remote controller I (2)also can detect and display temperature and humidity, set humidity, and send real-time temperature and humidity signals to the infrared signal receiver (12) at certain time intervals in a switched-onstate so that the control unit (13) can make logical judgment. Thus, the function of accurately controlling the human sensible temperature and humidity is achieved at a very low cost, and the comfortis significantly improved.

Description

technical field [0001] The invention relates to air conditioning technology, in particular to a low-cost comfortable air conditioner. Background technique [0002] Ordinary household air conditioners usually have two shortcomings: 1) Due to the installation location and orientation of the indoor unit of the air conditioner, the height and area of ​​the room, and the lack of sealing, heat insulation and sun protection capabilities of ordinary window glass, the indoor temperature distribution is not uniform. The temperature sensed by the temperature probe at the return air outlet of the indoor unit or in the control panel installed on the wall cannot really represent the indoor temperature, especially the temperature in the position where people sit or lie for a long time, resulting in the same temperature being set in different rooms It will make the same person have different feelings, even if the same temperature is set in the same room but the wind speed is different, the ...

Problems solved by technology

[0002] Ordinary household air conditioners usually have two shortcomings: 1) Due to the installation location and orientation of the indoor unit of the air conditioner, the height and area of ​​the room, and the lack of sealing, heat insulation and sun protection capabilities of ordinary window glass, the indoor temperature distribution is not uniform. The temperature sensed by the temperature probe at the return air outlet of the indoor unit or in the control panel installed on the wall cannot really represent the indoor temperature, especially the temperature in the position where people sit or lie for a long time, resulting in the same temperature being set in different rooms It will make the same person have different feelings, even if the same temperature is set in the same room but the wind speed is different, the same person will have different feelings, which affects the comfort; 2) The impact of humidity on human comfort is actually more than that of temperature. However, ordinary air conditioners do not have the ability to actively and accurately control the humidity. They only dehumidify while cooling. In weather where the temperature is not high but the humidity is high, the fixed-frequency air conditioner will stop cooling after a short working time. At this time, the dehumidification function is synchronized. Stop, the inverter air conditioner will cool with low power. At this time, the dehumidification capacity is very low, resulting in the problem that the indoor temperature is acceptable but the humidity is too high, that is, the lack of comfort

Precision air conditioners can solve all or part of the above problems, but they are not common in the household field, and their prices are not affordable for ordinary users
