The invention provides a radiation refrigeration air conditioner with a dehumidification function and a control method of the radiation refrigeration air conditioner. The radiation refrigeration air conditioner comprises an outdoor unit and an indoor unit, which form a closed loop through pipelines, wherein the outdoor unit comprises a compressor, a four-way valve, an outdoor heat exchanger and a first throttling device, which are sequentially connected in series; the indoor unit comprises an indoor refrigeration dehumidification passage and an indoor radiation refrigeration passage, which are connected in parallel; and a second throttling device connected in series with the indoor refrigeration dehumidification passage is arranged in front of the indoor refrigeration dehumidification passage. According to the radiation refrigeration air conditioner with the dehumidification function and the control method of the radiation refrigeration air conditioner, provided by the invention, an indoor heat exchanger is divided into an upper system and a lower system, which are connected in parallel, the upper system is a refrigeration dehumidification module, the lower system is a refrigeration module, working conditions are controlled through the throttling devices respectively, and meanwhile the working frequency of the compressor is controlled by measuring the indoor humidity. The radiation refrigeration air conditioner is simple in structure and convenient to use.
Description
technical field [0001] The invention belongs to the field of air-conditioning equipment, and in particular relates to a radiation refrigeration air-conditioner with a dehumidification function and a control method thereof. Background technique [0002] Nowadays, air conditioners have become a necessity in people's lives, and there are more and more styles of air conditioners.
