Single-cooling air conditioning system capable of dehumidifying without cooling and control method

Abstract

The invention discloses a single-cooling air conditioning system capable of dehumidifying without cooling and a control method. The single-cooling air conditioning system comprises a compressor, an electromagnetic three-way flow valve, a condenser, a filter, a first throttling module, a first stop valve, a first evaporator assembly, a second stop valve, a third stop valve, a second evaporator assembly, a second throttling module and an electromagnetic valve, wherein an exhaust port of the compressor communicates with a first port of the electromagnetic three-way flow valve; a second port of the electromagnetic three-way flow valve is connected with an inlet of the condenser; an outlet of the condenser is connected with an inlet of the filter; an outlet of the filter is connected with an inlet of the first throttling module; an outlet of the first throttling module is connected with the first stop valve; an outlet of the first stop valve is connected with an inlet of the first evaporator assembly; an outlet of the first evaporator assembly is connected with an inlet of the second stop valve; a third port of the electromagnetic three-way flow valve is connected with an inlet of a third stop valve; an outlet of the third stop valve is connected with an inlet of the second evaporator assembly; an outlet of the second evaporator assembly is connected with the second throttling module; and an outlet of the second throttling module is connected with the first evaporator assembly. According to the single-cooling air conditioning system capable of dehumidifying without cooling and the control method, the system is reasonable in connection design, simple in structure and low in manufacturing cost, a user can select and add a function of dehumidification without cooling according to needs, operation and adjustment are flexible, the requirements of various air conditioners are met, people feel comfortable, experience is good, and the satisfaction degree of the user and the comfort of the air conditioners are improved.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to a cooling-only air-conditioning system capable of dehumidification without cooling and a control method. Background technique [0002] According to market research and patent retrieval, in the ever-changing social living environment, people's demand for life is constantly increasing, and the quality of life is also constantly improving. Creating a comfortable living and working environment is an increasingly urgent thing; at the same time , air conditioners continue to enter the homes of ordinary people, and every household can use air conditioners, and air conditioners are not only able to meet the requirements of cooling and heating in the traditional sense; The requirements are getting higher and higher, and the research on technologies for sustainable development is particularly urgent. [0003] At present, the dehumidification mode of the air-conditioning system is set by the u...

Problems solved by technology

[0003] At present, the dehumidification mode of the air-conditioning system is set by the user. The dehumidification method of the general air conditioner is actually a process of condensing and discharging the water vapor in the indoor environment by running cooling. The control strategy is based on the user-set temperature -2 / 3 ℃ to control the operation of the air conditioner. For example, if the user sets 26 ℃ for dehumidification, the actual air conditioner will operate according to the current set temperature of the preset program - 2 / 3 ℃, which is 24 / 23 ℃. Therefore, at the same set temperature , the dehumidification mode often feels colder than the cooling mode, but in this method, such as the rainy weather, the temperature is not very high but the humidity is low, and the cooling operation will bring about a drop in temperature, which will seriously affect the comfort of the user
