(V ₂ ) is provided, the high-temperature, high-pressure refrigerant supplied through the compressor 13 is the first heat exchanger 16 or the second heat exchanger according to the opening and closing direction of the first direction switching solenoid valve (V ₁ ) The flow path is selectively changed to (17).

In addition, the freeze detection sensors 41 and 42 attached to the first and second heat exchangers 16 and 17 respectively detect the freezing to operate the bypass solenoid valve to convert the high temperature and high pressure refrigerant of the compressor discharge port into the compressor suction port. It prevents freezing by pipes, and it is configured to operate the cooling and heating cycle smoothly.

In the drawing, reference numeral 38 denotes a control panel, which is operated from the cold / hot air selection switch S ₁ and the air flow selection switch S ₂ and from the temperature sensor 40 and the pressure sensor _{SP as shown in} FIG. According to the detection signal, the compressor 13, the first motor 20, the second motor 21, the heater 25, and various solenoid valves V ₁ , V ₂ , V ₃ , V _4, V _5, etc. To drive control the electric actuators whose operation is controlled.

The operation at the time of cooling or heating is demonstrated below.

Ⓐ Cooling

During the cooling in the summer, the cooling cycle (a) is operated. The cold and hot air selection switches (S ₁ ) are placed in the cooling state, and the strong air or weak air and the desired room temperature are selected by operating the air volume selection switch (S ₂ ).

Accordingly, the compressor 13 is driven according to the control of the control panel 38 to compress and supply the refrigerant gas at high temperature and high pressure through the first refrigerant line L ₁ , and the first directional solenoid valve V ₁ Since the refrigerant line L ₅ is controlled to communicate with the first refrigerant line L ₁ instead of blocking, the refrigerant gas is circulated to the first heat exchanger 16, where the first motor of the first blower 22 is connected. (20) is driven and heat exchange occurs while air is introduced into the device casing (3) through the first grill (4), so that the refrigerant gas of high temperature and high pressure is condensed into the liquid refrigerant of high temperature and high pressure (the heated air Discharged to the outside through the third grill (6)), the condensate generated on the outer periphery of the first heat exchanger (16) is collected in the condensate collector (26) and collected into the condensate collector (14), After passing through), the one-way valve (32) is in the forward direction and passes through the dryer (33) to the first capillary tube (3). 1) It rapidly expands and becomes a gas of low temperature and low pressure, and the low temperature and low pressure vaporized gas is driven through the second grill 5 by driving the second motor 21 in the second heat exchanger 17. 3) The heat exchanges with the air introduced into the air, and the air cools down. Instead, the refrigerant gas absorbs heat and heats up.

The cold air is blown into the room through the upper fourth grill 7 to cool the room temperature, and the warmed refrigerant gas passing through the second heat exchanger 17 passes through the fourth refrigerant line 14. After entering the compressor (13) again compressed into a gas of high temperature and high pressure and repeats the same circulation process.

Therefore, all two-way solenoid valves (V ₁ , V ₂ , V ₃ , V ₄ ) shut off the piping lines of the heating cycle (ⓑ) and open the piping lines of the cooling cycle (ⓐ) when the cooling system is in operation. 38).

Ⓑ Heating

When heating in winter, the heating cycle (ⓑ) is operated. The cold and hot air selector switch (S ₁ ) is operated to be positioned at the heating position, and the airflow selector switch (S ₂ ) is operated to control the strong wind, the weak wind, and the desired room temperature. Choose.

Accordingly, the control panel 38 drives the first motor 20 and the second motor 21 and switches the direction switching solenoid valves V ₁ , V ₂ , V ₃ , V ₄ to cool the cooling cycle (ⓐ). Block the path of and control the opening of the path of the heating cycle (ⓑ).

Accordingly, the high temperature and high pressure refrigerant gas supplied from the compressor 13 flows along the opened fifth refrigerant line L ₅ and flows into the second heat exchanger 17, and the second heat exchanger 17 is cooled in a cooling cycle. The function is switched to the condenser as opposed to the function (function as an evaporator for cooling the blowing air).

In the second heat exchanger 17, the refrigerant gas is introduced into the device casing 3 through the second grill 5 through the driving of the second motor 21, and exits through the fourth grill 7. The heat exchange with the air causes the refrigerant to condense into a liquid of high temperature and high pressure. The refrigerant of the high temperature and high pressure passes through the one-way valve 34, the dryer 35, and the second capillary tube 36 along the third refrigerant line L ₃ . As it passes, it expands rapidly and becomes a refrigerant gas of low temperature and low pressure.

During this process, the air heated by the heat exchange in the second heat exchanger 17 is blown into the room through the fourth grill 7 by driving the fan 19 to heat the room, and then the second capillary tube 36 The refrigerant gas rapidly expanding through the low temperature and low pressure causes heat exchange with the air blown by the first motor 20 through the first heat exchanger 16. The air cooled by the heat exchange in the first heat exchanger 16 is discharged to the outside of the device casing 3 through the third grill 6, and the refrigerant gas which is heated by taking heat away from the air is the seventh refrigerant line ( L ₇ ) is compressed into a high temperature and high pressure through the compressor (13) and is then heated again by repeating the previous process.

Here, when the temperature of the room cannot be comfortably maintained by the air blown into the room through the third grill 7 due to the lack of heat radiation, the heater 25 is operated by receiving the information from the temperature sensor 40. Will assist.

Therefore, since the heater 25 is an auxiliary heating means, its capacity has a very small capacity compared with the conventional heater heating apparatus.

In this way, during the summer cooling, the cold air is blown into the room through the second grill (5) to cool the air, and during the winter heating, the hot air is blown through the second grill (5) to heat the cooling cycle. It is possible to combine heating and cooling by configuring the heating cycle as one common device.

Here, the reference numerals 41 and 42 denote freezing sensors, and when the first heat exchanger 16 and the second heat exchanger 17 function as an evaporator, a freezing phenomenon occurs due to overcooling and causes the control panel 38 to detect the first. The freeze detection sensor installed in each of the two heat exchanger chambers detects the freezing and activates the bypass solenoid valve to pipe the refrigerant at the high temperature and high pressure from the compressor outlet to the compressor inlet to prevent freezing, thus allowing the cooling and heating cycles to operate smoothly. It is to prevent the freezing, and the temperature setting unit 43 is to input the desired cooling, heating temperature, by comparing the input temperature and the current temperature detected from the temperature sensor 40 to continue to operate the device or Alternatively, the control panel 38 controls to pause.

The present invention as described above can solve the summer cooling and winter heating at the same time with a single device, it is possible to save the high cost due to the winter oil heating or the use of a high-power heater economical effect.
