Refrigeration and heat exchanging equipment and air conditioner including same

Abstract

The invention provides refrigeration and heat exchanging equipment, and further discloses an air conditioner. The refrigeration and heat exchanging equipment comprises a first heat transferring loop and a second heat transferring loop, a refrigerant flows in the first heat transferring loop, and moisture absorption solution flows in the second heat transferring loop; the refrigeration and heat exchanging equipment further at least comprises a first heat exchanging region, a second heat exchanging region and a third heat exchanging region; the refrigerant flowing in the first heat transferringloop and the moisture absorption solution flowing in the second heat transferring loop are subjected to heat exchanging in the first heat exchanging region, the refrigerant after being subjected to heat exchanging flows into the second heat exchanging region to be subjected to heat exchanging with an air medium, and the moisture absorption solution in the second heat transferring loop and the airmedium are subjected to heat exchanging in the third heat exchanging region. According to the refrigeration and heat exchanging equipment, it can be ensured that when the small air conditioner adopting a liquid dehumidification mode is used under a high temperature and high humidity state, air exhausting sensible heat of a compressor can be subjected to heat exchanging in the mode of air-liquid heat exchanging, so that the air conditioner realizes dehumidification-regeneration circulation on the premise that additionally-arranged heat sources are not added, and has the high heat exchanging efficiency.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a refrigeration heat exchange device suitable for high-temperature and high-humidity areas and an air conditioner equipped with the refrigeration heat exchange device. Background technique [0002] In areas with high temperature and high humidity such as Southeast Asia, high humidity is the main factor restricting the development of air conditioners. Air dehumidification is performed by three common devices in common air conditioners in the prior art. The first is the freezing dehumidification device. That is, the cooling and dehumidification capacity of the evaporator of the refrigerator system is used to dehumidify the air. The air is first cooled and dehumidified by the evaporator, and then wet-heated by the condenser. The specific enthalpy of the outlet air is larger than the specific enthalpy of the inlet air. It is not difficult to understand that the added heat is the equ...

Problems solved by technology

[0003] It is not difficult to see from the comparison that the dehumidification effect of the first refrigeration dehumidification device mainly depends on the performance of the compressor itself. For areas with a humidity of 60% to 80%, the input cost of the compressor is acceptable, but for humidity For areas where the annual temperature is higher than 80% and the temperature is higher than 30°C, the equipment cost and operating cost of the compressor are higher

For the second type of rotary dehumidification device and the third type of liquid dehumidification device, the equipment is complex, the initial investment is huge, and a matching heat source is also required, and it is basically impossible to put it into use in a domestic environment or a small-area cooling space

Moreover, when liquid dehumidification or solid dehumidification is used, especially when liquid dehumidification is used, the refrigerant or moisture absorbent must be provided with an additional heating coil in the pipeline, and it will be realized through frequent multiple heat exchanges with the heating coil. Dehumidification and heat exchange are also limited by the size of household air conditioners. There is no refrigeration and heat exchange equipment suitable for liquid dehumidification or solid dehumidification in the prior art.

[0004] To sum up, there is a lack of refrigeration and heat exchange equipment in the prior art that can be used in household or small-area refrigeration spaces, and can meet the needs of dehumidification and refrigeration in high-temperature and high-humidity areas.
