Definitions

  • the present invention belongs to the technical field of air conditioners, and more particularly relates to an air conditioner system.
  • An existing air conditioner system generally uses a condenser, a throttle device, an evaporator and a compressor to form a refrigeration/heating cycle circuit.
  • a high-temperature high-pressure gaseous refrigerant discharged by the compressor is condensed into low-temperature high-pressure liquid in the condenser, is throttled into low-temperature low-pressure liquid through the throttle device, and then enters the evaporator to absorb heat and evaporate to finish a refrigeration/heating cycle.
  • a low-temperature high-pressure liquid refrigerant is formed after the high-temperature high-pressure gaseous refrigerant exchanges heat through the condenser, and then, through throttling and pressure reduction by the throttle device, a low-temperature low-pressure gas-liquid two-phase region refrigerant is formed, and enters the evaporator for heat exchange.
  • FIG. 3 is a schematic cycle diagram of a conventional air conditioner during heating operation.
  • actual operation temperature points of the heating operation of the air conditioner are generally as follows: from a point A, a high-temperature gaseous refrigerant being 70°C enters an indoor heat exchanger and an indoor environment being 20°C for heat exchange to lower the temperature to 30°C, and enters the throttle device after flowing through an on-line pipe, wherein the temperature (about 30°C) between a point B and the throttle device is much higher than an outdoor environment temperature being 7°C, and afterheat is wasted. If the afterheat is absorbed and used, the degree of supercooling of the system cycle can also be increased.
  • JP 2016 106211 A describes an air conditioner, which is an air exchanger provided with a main pipe for connecting an indoor unit and an outdoor unit so that a refrigerant circulates.
  • EP 2 378 215 A1 discloses an air conditioner system that can perform simultaneous defrosting and heating.
  • the air conditioner system comprises a compressor, an indoor heat exchanger, a first throttle device, and an outdoor heat exchanger connected in series in a main circuit, wherein the main circuit is also provided with a heat exchanger and a first gas-liquid separator, wherein a bypass defrosting circuit is disposed between the compressor and the outdoor heat exchanger, wherein one side of the heat exchanger is connected to a first pipeline between the first throttle device and the indoor heat exchanger, and the other side of the heat exchanger is connected to a second pipeline between the first throttle device and the outdoor heat exchanger, so that a refrigerant passing through the first pipeline and a refrigerant passing through the second pipeline can exchange heat in the heat exchanger, wherein the first gas-liquid separator is positioned in a second pipeline section between the heat exchanger and the indoor heat exchanger, and a bypass pipeline is disposed between the first gas-liquid separator and the compressor, and wherein the bypass de
  • an air conditioner system according to claim 1 is provided.

  • the heat exchanger is added to the air conditioner system, and the two sides of the heat exchanger are respectively connected to the first pipeline and the second pipeline. Therefore, the refrigerant in the first pipeline and the refrigerant in the second pipeline can exchange heat in the heat exchanger. Not only is the degree of supercooling of the refrigerant in the first pipeline effectively increased, but also the evaporation of the refrigerant in the second pipeline can be promoted, so that a heating capacity of the system is improved.
  • bypass pipeline is disposed between the first gas-liquid separator and the compressor, and the gaseous refrigerant passing through the gas-liquid separator can enter an air suction opening of the compressor through this bypass pipeline, so that the pressure loss of this part of the gaseous refrigerant in a heating cycle is reduced, which is equivalent to that the pressure of the air suction opening of the compressor is increased, the power consumption of the compressor is further reduced, the circulation volume of the refrigerant during the heating cycle of the air conditioner system is increased, and the purpose of improving the heating capacity is achieved.
  • the bypass defrosting circuit is also added.
  • the air conditioner of the present invention is also provided with the third throttle device, so that when the air conditioner is switched to the refrigeration mode, the third throttle device is used to replace the first throttle device (at the moment, the first throttle device is in the fully open state) to throttle the refrigerant. Therefore, the occurrence of a phenomenon that a refrigeration capacity is reduced in a refrigeration cycle is avoided.

  • the first pipeline M passes through one side of the heat exchanger 5, and the second pipeline N passes through the other side of the heat exchanger N.
  • a refrigerant passing through the first pipeline M and a refrigerant passing through the second pipeline N can exchange heat in the heat exchanger 5.
  • the main circuit is also provided with a first gas-liquid separator 6.
  • the first gas-liquid separator 6 is positioned in a second pipeline N section between the heat exchanger 5 and the outdoor heat exchanger 4, and a bypass pipeline L is disposed between the first gas-liquid separator 6 and the compressor 1.

  • the refrigerant in the first pipeline M and the refrigerant in the second pipeline N have temperature differences, and both pass through the heat exchanger 5, so that the refrigerant in the first pipeline M and the refrigerant in the second pipeline N exchange heat in the heat exchanger 5.
  • the degree of supercooling of the refrigerant in the first pipeline M effectively increased (i.e., the part of refrigerant from the point C to the first throttle 3 continues to release heat to lower the temperature), but also the evaporation of the refrigerant in the second pipeline N can be promoted (i.e., the low-temperature refrigerant at the point D can perform evaporation heat absorption on afterheat at the point C, which is equivalent to that the evaporation area is increased, and the heat exchange capability is effectively improved), so that a heating capacity is improved.
  • the refrigerant exchanging heat through the heat exchanger 5 enters the first gas-liquid separator 6.
  • the gaseous refrigerant separated by the first gas-liquid separator 6 directly flows back into the compressor 1 along the bypass pipeline L, so that the pressure loss of this part of the gaseous refrigerant in a heating cycle is reduced, which is equivalent to that the pressure of an air suction opening of the compressor 1 is increased, the power consumption of the compressor 1 is further reduced, the circulation volume of the refrigerant during the heating cycle of the air conditioner system is increased, and the purpose of improving the heating capacity is achieved.

  • the above-mentioned heat exchanger 5 may be a water tank containing water or may be in any other suitable form, provided that the refrigerants at the upstream and downstream of the first throttle device 3 can exchange heat. Additionally, the design can effectively improve the heating capacity for the heating cycle and reduce a refrigeration capacity for the refrigeration cycle.
