Household air conditioner device capable of adjusting temperature and humidity respectively

Abstract

The invention discloses a household air conditioner device capable of adjusting temperature and humidity respectively. The household air conditioner device is characterized by comprising a refrigerating system and an air processing part. The refrigerating system comprises a compressor (1), a four-way valve (2), a first heat exchanger (3), a first one-way valve (4), a second one-way valve (5), a reservoir (6), a filter (7), a first electronic expansion valve (8), a third one-way valve (9), a fourth one-way valve (10), a second heat exchanger (11), a first gas-liquid separator (12), a second electronic expansion valve (13) and a third heat exchanger (14). An output end of the compressor (1) is connected with a first input end (2a) of the four-way valve. A first output end (2b) of the four-way valve is connected with an input end (3a) of the first heat exchanger. An output end (3b) is connected with an input end of the reservoir (6) through the first one-way valve (4). Indoor temperature and humidity can be adjusted independently by aid of the household air conditioner device.

Description

technical field [0001] The invention relates to a novel household air conditioner capable of separately adjusting indoor air temperature and humidity, and belongs to the technical field of refrigeration and air conditioning system design and manufacture. Background technique [0002] With the gradual consumption of fossil energy, the energy problem has become one of the most serious problems that restrict my country's economic development. With the acceleration of urbanization, the energy consumption of buildings has accounted for more than 30% of the total energy consumption of the whole society. And the proportion is still increasing. At the same time, with the improvement of people's living standards, people's requirements for the comfort of work, life and study are getting higher and higher. As the main place for people to work, live and study, the building indoor environment mainly adopts building air conditioning The improvement of indoor comfort will inevitably put fo...

Problems solved by technology

In order to ensure the dehumidification effect in the design of conventional household air conditioners, the operating evaporation temperature is usually designed to be low, but in actual operation, the treatment of sensible heat load is given priority, and the indoor air temperature is taken as the target control parameter, so that the adjustment of humidity cannot be realized

When the sensible heat load in the room is large and the humidity load is small, or the room air conditioner runs for a long time, there will be transitional dehumidification in the room, that is, the relative humidity in the room is too low, resulting in a phenomenon that the comfort of the indoor occupants is greatly reduced. Due to excessive dehumidification, the indoor and outdoor humidity difference increases, the outdoor humid air penetrates into the room, and the humidity load of the air conditioner increases, thus increasing the energy consumption of the air conditioner.

[0004] Therefore, to solve the problem of separate processing of indoor air-conditioning load, realize independent adjustment of indoor temperature and humidity, and improve system performance while improving indoor comfort, a new type of high-efficiency household air-conditioning device that realizes separate adjustment of temperature and humidity is designed. Become a technical problem that those skilled in the art urgently need to solve
