Embodiment 1

[0058]In this example, please refer toFigure 2 to Figure 5The refrigerant path 22 of the double-pipe heat exchanger 2 and the refrigerant path of the tube-fin condenser 6 are arranged in parallel between the exhaust port of the compressor 7 and the throttling device 11. This air conditioner The specific structure of the air system, water system and refrigerant system of the machine is as follows:

[0059]Wind road system

[0060]The inlet of the air passage of the evaporator 3 is connected with the toilet through the hot fluid passage of the cross-flow heat exchanger 5, and the outlet of the air passage of the evaporator 3 is connected with the inlet of the cold fluid passage of the cross-flow heat exchanger 5; the tube-fin condenser 6 The inlet of the air path is connected with the outlet of the cold fluid channel of the cross-flow heat exchanger 5, the outlet of the air path of the tube-fin condenser 6 is connected with the suction port of the fan 9, and the exhaust port of the fan 9 is...

Embodiment 2

[0078]The difference between this embodiment and embodiment 1 is that the refrigerant path 22 of the double-pipe heat exchanger 2 and the refrigerant path of the tube-fin condenser 6 are arranged in series at the exhaust port of the compressor 7 And throttling device 11, please refer toFigure 6 withFigure 7 , The specific structure of the air system, water system and refrigerant system of this air conditioner is as follows:

[0079]Wind road system: same as Example 1.

[0080]Waterway system: the same as in Example 1.

[0081]Refrigerant circuit system: the exhaust port of the compressor 7 is connected with the inlet of the refrigerant circuit 22 of the tube-and-tube heat exchanger 2, and the refrigerant circuit 22 outlet of the tube-and-tube heat exchanger 2 and the tube-fin condenser 6 are refrigerated The inlet of the medium is communicated, and the outlet of the refrigerant of the tube-fin condenser 6 is communicated with the suction port of the compressor 7 through the throttling device...

Abstract

The invention relates to a dehumidifying, cooling, heating and drying air conditioner adopting a double-pipe heat exchanger to recover heat. The dehumidifying, cooling, heating and drying air conditioner comprises a compressor, a condenser, a throttling device and an evaporator, wherein the compressor, the condenser, the throttling device and the evaporator are sequentially connected to form a refrigerant circulating system; the condenser comprises a tube-fin condenser and the double-pipe heat exchanger; the double-pipe heat exchanger comprises a refrigerant path for circulating a refrigerantand a water path for circulating cold water; and the refrigerant path of the double-pipe heat exchanger and the refrigerant path of the tube-fin condenser are arranged between an exhaust port of the compressor and the throttling device in parallel or in series.

Description

Technical field[0001]The invention relates to the technical field of heat pumps, and in particular to a dehumidification, temperature reduction, heating and drying air conditioner adopting a sleeve-type heat exchanger to recover heat.Background technique[0002]After 30 years of hard work, the heating problem of family bathing space in winter has been generally solved. With people's pursuit of a better life, the problem of cooling and dehumidifying the bathroom space during toileting and bathing in summer has become a new focus of the sanitary product industry.[0003]The demand for cooling and dehumidification of the family bathroom space occurs at three points:[0004]1. Go to the toilet in summer[0005]The function of the family bathroom is important, but the space is small, a partition is set between the bathroom space and the toilet, and the time utilization rate is very low, and air conditioning is generally not installed;[0006]When going to the toilet in summer, or when using the ba...
