[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0025] The air conditioner provided by the utility model can be an industrial air conditioner, a household air conditioner or a car air conditioner, especially an air conditioner used in scenarios with relatively many people or wet loads such as in a car. It can achieve independent temperature and humidity regulation, which is different from the traditional temperature and humidity combined regulation method, reduces the energy consumption of the air conditioner and improves the temperature and humidity regulation efficiency.
[0026] In a specific embodiment, Figure 1 and Figure 2 As shown, the air conditioner with independent temperature and humidity regulation provided by the utility model includes an indoor unit 100 and an outdoor unit 200; wherein, the indoor unit 100 includes a temperature regulating heat exchanger and a humidity regulating heat exchanger which are independently arranged, and the temperature regulating heat exchanger and the humidity regulating heat exchanger are arranged front and back in the return air direction; the outdoor unit 200 includes a high-temperature working condition refrigeration system and a normal working condition refrigeration system which are independent of each other, and the high-temperature working condition refrigeration system is connected to the refrigerant interface of the temperature regulating heat exchanger through a refrigerant pipeline, and the normal working condition refrigeration system is connected to the refrigerant interface of the humidity regulating heat exchanger through a refrigerant pipeline.
[0027] That is to say, the indoor unit 100 is provided with a mutual temperature regulating heat exchanger and a humidity regulating heat exchanger, and the temperature and humidity regulating indoor unit 100 is used for sharing. The indoor unit 100 includes a fan 31, an air supply port 32, a temperature regulating indoor unit evaporator 33, a humidity regulating indoor unit evaporator 34 and a return air port 35; wherein the temperature regulating heat exchanger and the humidity regulating heat exchanger are arranged in front and behind, and the return air passes through the temperature regulating heat exchanger and the humidity regulating heat exchanger in sequence after passing through the return air port. The temperature regulating heat exchanger is connected to the high temperature working condition refrigeration system of the outdoor unit through a refrigerant pipe, and the humidity regulating heat exchanger is connected to the ordinary working condition refrigeration system of the outdoor unit through a refrigerant pipe. The outdoor unit 200 is provided with two independent compressors and condensers, which are respectively the ordinary working condition refrigeration system and the high temperature working condition refrigeration system; the ordinary working condition refrigeration system includes a compressor 11 and an evaporator (heat exchanger in the humidity regulating air duct) of the ordinary working condition refrigeration system, a condenser 12 of the ordinary working condition refrigeration system, an interface 13 and a throttling device of the ordinary working condition refrigeration system, and the evaporation temperature of the ordinary working condition refrigeration system is controlled at about 5°C. The high temperature working condition refrigeration system includes a compressor 21 of the high temperature working condition refrigeration system, an evaporator (evaporator in the temperature regulating air duct), a condenser 22 of the high temperature working condition refrigeration system, an interface 23 of the high temperature working condition refrigeration system and a throttling device. The high temperature working condition refrigeration system can switch the evaporation temperature between 15°C and 5°C through the throttling device module, and the high temperature working condition refrigeration system is converted into a normal working condition refrigeration system.
[0028] It should be understood that, for the structures of other parts of the air conditioner, the indoor unit 100 and the outdoor unit 200 provided by the present invention, please refer to the prior art and will not be described in detail here.
[0029] Specifically, the temperature regulating heat exchanger and the humidity regulating heat exchanger use the same windward area or different windward areas.
[0030] In some embodiments, the frontal area of the temperature regulating heat exchanger is the same as the frontal area of the humidity regulating heat exchanger.
[0031] When the windward area of the temperature regulating heat exchanger is the same as the windward area of the humidity regulating heat exchanger, the heat transfer coil spacing of the humidity regulating heat exchanger is greater than the heat transfer coil spacing of the temperature regulating heat exchanger; and / or, the fin spacing of the humidity regulating heat exchanger is greater than the fin spacing of the temperature regulating heat exchanger.
[0032] When the windward area of the temperature control heat exchanger is the same as the windward area of the humidity control heat exchanger, the humidity control heat exchanger is larger than the heat transfer coil spacing and / or fin spacing of the temperature control heat exchanger, so that the frontal wind speed of the heat exchanger can be larger, and the phenomenon of the condensed water of the heat exchanger being blown away and replaced into the air duct will not occur. This is due to the special design when the windward area of the temperature control heat exchanger is the same as the windward area of the humidity control heat exchanger, so that the air volume of the temperature control heat exchanger is the same as the air volume of the humidity control heat exchanger, but the minimum flow section wind speed of the humidity control heat exchanger is less than its critical wind speed for water drift. At the same time, such a design will make full use of the excess air volume of the temperature control heat exchanger, so that the excess air volume of the humidity heat exchanger will be greater than the excess air volume in its conventional design, which can improve its heat exchange efficiency and increase the evaporation temperature of the refrigeration system under normal working conditions, thereby greatly improving its COP.
[0033] When the temperature regulating heat exchanger and the humidity regulating heat exchanger have different frontal areas, the frontal area of the temperature regulating heat exchanger is larger than the frontal area of the humidity regulating heat exchanger. At this time, the return air first passes through the temperature regulating heat exchanger for temperature regulation, and then is divided into two parts, one of which passes through the humidity regulating heat exchanger for humidity regulation, and is mixed with the other part of the return air that has not been humidity regulated and sent into the room.
[0034] In the above specific implementation manner, in the air conditioner with independent temperature and humidity regulation provided by the utility model, the temperature regulating heat exchanger and the humidity regulating heat exchanger are arranged in front and behind, so that the return air first passes through the temperature regulating heat exchanger to process its sensible heat load, and then passes through the humidity regulating heat exchanger to process its latent heat load. In this way, a larger dehumidification processing capacity is obtained while the total air volume is not much increased compared with the traditional temperature and humidity coupling regulation technology route; thereby, the high efficiency of independent temperature and humidity regulation can be guaranteed, and the requirement of high dehumidification capacity can be met.
