Definitions

  • the present application relates to the field of air-conditioning equipment, and specifically to a multi-split air conditioner capable of refrigerating and heating simultaneously.
  • An air conditioning device is referred to as an air conditioner.
  • a wall-mounted air conditioner is a unit for providing conditioned air into a spatial region (generally being closed), and has a function of adjusting various parameters, such as temperature, humidity, purity and air flowing rate, of air in a room (or a closed space or region) so as to meet requirements for human comfort or manufacturing processes.
  • the working principle of the air conditioner is as follows: gaseous refrigerant is compressed by a compressor into liquid refrigerant with high temperature and high pressure which is in turn transported to a condenser (an outdoor unit) for dissipating heat and then becomes liquid refrigerant with ambient temperature and high pressure, such that hot air is blown out from the outdoor unit; and due to a component referred to as a four-way valve, the flow direction of the refrigerant between the condenser and an evaporator in heating process is opposite to that in refrigerating process, such that in heating process, cold air is blown out from the outdoor unit and hot air is blown out from an indoor unit.
  • a multi-split air conditioner refers to an air conditioner having a plurality of indoor units and a single outdoor unit.
  • the conventional multi-split air conditioner can only provide cooling or heating solely at a time.
  • the air conditioner may be also required to operate in refrigerating mode in winter.
  • the technical problem to be solved by the present application is to provide a multi-split air conditioner capable of refrigerating and heating simultaneously, which may operate in five modes of refrigerating solely, heating solely, refrigerating mainly, heating mainly, and refrigerating-heating equally.
  • a multi-split air conditioner capable of refrigerating and heating simultaneously includes a compressor, an oil-gas separator, a four-way valve, an outdoor heat exchanger, at least two indoor heat exchanging mechanisms and a gas-liquid separator, wherein:
  • the first control valve, the second control valve and the third control valve each are an electromagnetic valve.
  • the compressor is an inverter compressor.
  • the multi-split air conditioner capable of refrigerating and heating simultaneously according to the present application may be operated in five modes, i.e., solely refrigerating mode, solely heating mode, mainly refrigerating mode, mainly heating mode, and equally refrigerating-heating mode.
  • Fig. 1 is a structural schematic view of a multi-split air conditioner capable of refrigerating and heating simultaneously according to a preferred embodiment of the present application.
  • a multi-split air conditioner capable of refrigerating and heating simultaneously includes an inverter compressor, an oil-gas separator, a four-way valve, an outdoor heat exchanger, four indoor heat exchanging mechanisms and a gas-liquid separator, wherein:
  • FIG. 1 a structural schematic view of a multi-split air conditioner capable of refrigerating and heating simultaneously according to a preferred embodiment of the present application is shown.
  • the embodiment is described by taking the four indoor heat exchanging mechanisms as an example.
  • the multi-split air conditioner capable of refrigerating and heating simultaneously according to the present application may operates in five modes, i.e., solely refrigerating mode, solely heating mode, mainly refrigerating mode, mainly heating mode, and equally refrigerating-heating mode.
  • solely refrigerating mode solely heating mode
  • mainly refrigerating mode mainly heating mode
  • equally refrigerating-heating mode The specific operating principle and process of the air conditioner according to the present application will be described below.
