Abstract

An air conditioner comprising an outdoor unit and a dehumidifying-reheating indoor unit capable of avoiding uneven temperature distribution of the airflow provided by the dehumidifying-reheating indoor unit to the room and fully utilizing the dehumidifying heat exchanger and reheating of the dehumidifying-reheating indoor unit The role of the heat exchanger. In the air conditioner of the present invention, the outdoor unit includes a compression mechanism and an outdoor heat exchanger, the dehumidifying and reheating indoor unit includes a dehumidifying heat exchanger and a first indoor refrigerant adjustment device, and the air conditioner utilizes a suction pipe, a discharge pipe, and a first pipe. , The second piping connects the compression mechanism, the outdoor heat exchanger, the first indoor refrigerant regulating device and the dehumidification heat exchanger, and the air conditioner also includes a reheat heat exchanger, the second indoor refrigerant regulating device, and the third piping and the branch pipe, and the third pipe connects the first junction of the first pipe between the first indoor refrigerant regulating device and the outdoor heat exchanger, the second indoor refrigerant regulating device, the reheat heat exchanger, and the The branch pipes are connected sequentially.

Description

technical field [0001] The present invention relates to air conditioners. Background technique [0002] With the improvement of people's living standards, people's demand for living environment control has become increasingly prominent. Therefore, the function of air-conditioning devices has gradually developed from a single temperature adjustment to a diversified development. In humid and rainy areas and during the rainy season, the humidity of the air is relatively high, causing discomfort to the human body. Therefore, an air conditioner with a humidity control function has emerged as the times require. [0003] Air conditioning units typically dehumidify by passing air through a heat exchanger whose surface temperature is below the dew point of the air, causing the air to condense and thereby remove moisture from the air. According to the above dehumidification principle, it can be known that the lower the surface temperature of the heat exchanger, the better the dehumid...
