Air conditioner and dehumidifier combined device

Abstract

The invention relates to an air conditioner and dehumidifier combined device. The air conditioner and dehumidifier combined device is characterized in that in a split air conditioner, a throttle valve (2) is arranged in an indoor unit, and a compressor is arranged in an outdoor unit. An air conditioner refrigerant pipeline with an outdoor heat exchanger (3) as the starting point, passing the throttle valve (2) and with an indoor heat exchanger (4) as the terminal point is defined as a pipeline S, and a dehumidification loop connected with the pipeline S in parallel is additionally arranged in the indoor unit. The dehumidification loop communicates with the pipeline S at the position A and the position B of the pipeline S, the position B is located on the starting point side of the pipeline S, and the position A is located on the terminal point side. The corresponding positions of components on the dehumidification loop are A, a dehumidification control valve (7), a dehumidification evaporator (6), a dehumidification check valve (8) and B. The two valves of the dehumidification loop are closed, and the device is the air conditioner. A valve piece between the position A and the position B of the pipeline S is closed, flowing of a refrigerant between the position A and the position B of the pipeline S is isolated, the two valves on the dehumidification loop are opened, the indoor heat exchanger is a condenser, and the device is a dehumidifier. During dehumidification, the volume of air flowing through the indoor heat exchanger is larger than the air volume of the dehumidification evaporator by 1.2 times. The device is ingenious, simple and reliable in structure, high in dehumidification efficiency, large in dehumidification amount, convenient to install, and capable of achieving two purposes.

Description

technical field [0001] The invention relates to an air conditioner and dehumidifier combined device, which not only has the functions of heating and cooling air conditioners, but also has the functions of a dehumidifier, and belongs to the field of control and adjustment of indoor air temperature and humidity. Background technique [0002] Air conditioners and dehumidifiers are commonly used equipment for regulating temperature and humidity in buildings. Both air conditioners and dehumidifiers are heat pump systems that use the same components and operate on the same principle. However, the existing air conditioners and dehumidifiers often only focus on their independent applications, and fail to fully combine their functions into one; After the dehumidifier, you need to purchase another dehumidifier. However, the existing household dehumidifiers have low power and dehumidification capacity, high noise, and increase the indoor temperature during operation in summer, which ...

AI Technical Summary

Problems solved by technology

The more complex structure leads to an increase in cost and volume, and also leads to a decrease in the reliability of the equipment; in a heat pump system similar to an air conditioner, due to the high pressure of the refrigerant, the sealing of the two-way solenoid valve becomes poor, resulting in leakage of the refrigerant; there are Mature one-way shut-off valve, but lacks two-way shut-off valve for high-pressure refrigerant

If the refrigerant two-way shut-off valve is used reluctantly, it will lead to refrigerant leakage and failure caused by the shut-off valve, resulting in a solution that is theoretically feasible, but the actual product cannot be used stably. Experiments have proved this.
