Description of the invention (5) 31, 33, and the gates 36, formed in the air-space path and the remaining gates 32, 34, 35, and 37 o'clock are closed via the chamber cooled by the evaporator 2 It flows into the room through the indoor-side discharge port 11, and the internal air system flows to the evaporator 2 through the indoor-side suction port 12 through the indoor-side exhaust port 11. On the other side, two sigma-hot air and the external air flowing in from the outside suction port 14 are discharged through the condenser 3 ′ through the room and through the outdoor side discharge port 13 to the outside for heat absorption in the room. In this cold room mode, Suppose that the gates 31, 3 are opened. Opening degree is approximately 70% '36 of closed door 32, 34, 35, 37 '38 < 30%, 70% of cold indoor air and 30% of warmth required for ventilation are passed through while evaporating The condenser 2 supplies mixed air to the air in order to remove heat. At this time, a large amount of condensed water is generated by the evaporator 2 and spread. 22: Wide ° The efficiency of the condenser can be improved. That is, the condenser is used for both air cooling 7 and water cooling. In addition, 70% of the warm outdoor air and 30% of the cold indoor air required for ventilation are mixed to reduce the temperature. The combined air passing through the condenser 3 enhances the condensation efficiency of absorbing heat from the condenser 3. Referring to the third figure, when explaining the heating mode of the present invention, contrary to the above, the gates 32, 34 formed between the indoor air path and the condenser 3 and the gates 35, 37 formed between the outdoor air path and the evaporator 2 are opened. When the remaining gates 31, 33, 36, and 38 are closed, the indoor air heated by the condenser 3 flows into the room through the indoor outlet 11 and then flows through the condenser 3 through the indoor suction port 丄 2. On the other hand, the cold outside air that has flowed in through the outdoor side suction population 丨 4 is deprived of heat through the evaporator 2 and then discharged to the outside through the outdoor side discharge port 13 to play the role of indoor heating. In this greenhouse mode, if the gates 32, 34, 35, 37 are opened,

Description of the invention (6) The opening degree becomes 70% of the hook, and when the gate is closed, 70% of the blinds are closed * /, 6, and the opening degree becomes ~ 4, *, 0% of the warmth. The 30% cold outdoor room required for the second rolling and changing the atmosphere is heated and the mixed air heated by the condenser 3 is supplied to the room. 70% of the cold outdoor air and 30% of the warm air required for ventilating, and 30% of the warm indoor air required for ventilation, and the mixed air whose temperature rises due to passing through the evaporator 2 and the large evaporation 1§ 2 evaporation efficiency of heat absorption . Said another description of the present invention with reference to the fourth and fifth figures is that ιΤ and ί: T ′ has a humidity sensor in the room R, and a reheater 6 is attached between the indoor side discharge port and the evaporator 2. The reheater 6 is a supplementary condenser connected between the condenser 3 and the expansion valve 5 as shown in the fifth figure. A humidifier 8 is provided between the indoor-side discharge port 11 and the condenser 3. . The symbol 41 is a heat accumulator, 42 is an oil separator, 43 is a filter dry operation device, and 44 is a solenoid valve. Because it belongs to the channel including refrigerant circulation: σ, the description is omitted. The temperature of the condenser blower i0b formed to the outer exhaust port 13 is controlled by the humidity sensor 7 to control the amount of heat released from the condenser 3 in the cold room. By this, the heat of the reheater 6 connected to the rear end of the condenser 3 is increased or decreased, and the temperature of the heat flowing out of the indoor outlet 11 through the evaporator 2 is appropriately controlled by the heat release of the reheater 6, To adjust the relative humidity of the room, at this time, the more the heat increases, the more the refrigeration capacity is required. The increase in the amount of reheating heat causes the refrigerant flowing into the expansion valve 5 to be excessively cooled to increase the freezing capacity. Therefore, the problem of 'reheating does not cause a decrease in cooling energy & force. It is assumed that when the indoor relative humidity is lower than the target value, the normal cold room operation is used to increase the indoor relative humidity.

V. Description of the invention (7) 'And' When the relative humidity in the room is lower than the target value when the modal humidity sensor 7 in the warm room detects that the indoor humidity is lower than the target value, the humidifier 8 is activated, the condenser 3 is increased, and the exhaust port 11 is added from the inside Moisture from the air. Suppose that when the relative humidity in the room is higher than the target value, the normal relative room humidity is used to reduce the relative humidity in the room. For example, the adjustment of the opening degree of the gates 31 to 38 and the action of the reheater 6 and the humidifier 8 or the air volume of the blowers 10a, 10b, etc., are enriched by the humidity sensor 7 'and The temperature sensor and the set value entered by the user without permission are performed by the controller shown in the figure. The symbol 46 is a humidity conditioner ', which may form part of the controller or be separately installed. The sixth figure is an operation state diagram of the modal operation of the greenhouse according to the embodiment improved by the present invention. If this is the case, a supplementary condenser 3a is provided between the outdoor inlet 1-4 and the condenser 3, and the auxiliary condenser 3a is connected to the cold coal pipe 9 connected between the condenser 3 and the evaporator 2. At this time, the high-pressure refrigerant flowing into the auxiliary condenser 3a through the above-mentioned condenser 3 has a temperature of about 40 ° C due to the residual heat. Therefore, the outside air temperature can be preheated by using this. With the above structure, the openings of the opened gates 32, 34, 35, and 37 are approximately 70%. 'When the openings of the closed gates 31, 33, 3, 6, and 38 are 30%, 30 required for ventilation is required. % Cold air flows into the preheated state through the auxiliary condenser 3a. This is mixed with 70% of the warm indoor air flowing into the indoor side suction inlet 12 through the side while being heated by the condenser 3 and heated. The mixed air is supplied into the room. In addition, 70% of the cold outdoor air and 30% of the warm indoor air required for ventilation are mixed, and the mixed air with an increased temperature passes through the evaporator 2 to increase the evaporation efficiency of the heat absorption of the evaporator 2. In addition, the temperature of the cold outside air flowing into the room required for ventilation is preheated while passing through the auxiliary condenser 3a.

Page 11 V. Description of the invention (8), the inflow into the condenser 3 is heated, so its degree will increase the heating efficiency. [Effects of the invention] According to the present invention described above, it is a simple structured device generally composed of a cold coal cycle, which selectively adjusts the air flow direction and the flow rate by adjusting the outflow and inflow of indoor and outdoor air. It can be used as both a cold room and a warm room, and it can provide a cool and warm room combined air conditioner with a novel structure with excellent cooling and heating efficiency. In addition, the reheater and humidifier attached to the normal refrigerant cycle can provide precise control to maintain the indoor temperature and humidity, and provide excellent cooling and heating air conditioners even without additional equipment.
