The invention discloses a heat pump hot air heating unit with a dehumidifying function and a control method thereof. The heat pump hot air heating unit with the dehumidifying function comprises an outdoor unit and an indoor unit connected through a refrigerant circulating pipeline; the indoor unit comprises a first heat exchanger and a second heat exchanger; each of the first heat exchanger and the second heat exchanger comprises a first connector and a second connector; the second connector of the first heat exchanger is connected to each of the first connector of the second heat exchanger and the outdoor unit; the second connector of the second heat exchanger is connected to the outdoor unit; a first throttling part is also arranged between the first heat exchanger and the second heat exchanger; a control part is arranged between the second connector of the second heat exchanger and the outdoor unit; and the heat pump hot air heating unit with the dehumidifying function controls whether a refrigerant flows through the second heat exchanger for absorbing heat or not to achieve the purpose of dehumidifying by controlling the on-off state of an electronic shutoff valve. The heat pump hot air heating unit has the functions of dehumidifying while heating; the dehumidifying function is realized, and simultaneously, a heating effect is hardly influenced; and the functions of heatingand dehumidifying are realized very well.
Description
technical field [0001] The invention belongs to the field of dehumidification of air conditioners, and in particular relates to a heat pump hot air heating unit with a dehumidification function and a control method thereof. Background technique [0002] In the Yangtze River Basin in my country, the humidity is high in winter, and the phenomenon of "cold" in rooms is common. The current air conditioner does not have a dehumidification function when heating in winter. Therefore, under high humidity conditions, even if the room temperature reaches the set temperature, people will not feel warm. At the same temperature, the lower the air humidity, the higher the perceived temperature and the more comfortable the feeling. Therefore, design a unit with heating and dehumidification functions. [0003] In order to solve the above problems, the existing application number is 201210042267.8, which is called a Chinese invention patent of a heat pump air conditioner with dehumidificat...
