According to another characteristic of the present invention, the said heat exchange chamber 20 is separated in upper and lower heat exchange chambers 22, 23 by an orizontal separating plate 21, and that the evaporator 2 is adapted in the in cloned upper heat inlet chamber 22 and the co-condenser 3 is adapted in the lower heat exchange chamber 23, by this the water produced in the said porator 2 would flow down to said condenser 3. According to To an advanced feature of the invention, a humidity detector 7 is placed in a certain position inside the room R, and the recloser 6 is used to measure the condensed heat is connected to the room.

Coater 3 and a capillary expansion valve 5, and wherein said superheater 6 is col- ocated between said evaporator 2 and said upper air discharge door 11 to heat the discharged air within the interior of the room. The chosen embodiment of the present invention is explained below in relation to the appended figures. Figure 1 shows a perspective view of a selected mode of the present invention which is partially sectioned and Figures 2 and 3 each show the operating status in the cooler and heater functions. As may be, a discharge door 11 on the interior side and an entrance door 12 on the interior side are positioned in opposition to the group of a discharge door 13 on the exterior side and an entrance panel 14 on the side e terior in a case 1. The discharge door 11 on the interior side and the discharge door 13 e on the outside side are separated by a partition wall 25, while the entrance door 12 on the side The interior and the entrance door 14 on the outer side are separated by a separating wall 26. Between the unloading doors 11, 13 and the entrance doors 12, 14 is placed a heat exchange chamber 20, which is limited by the respective regulators 31-38. The heat exchange chamber 20 in tur or is di- arated by a separating plate 21 hori- zontally disposed within the upper heat exchange chamber 22 to receive the evapo- rator 2 and the lower heat bio chamber. 23 to receive a condenser 3. The condensed water produced in the erator 2 in the upper heat exchange chamber 22 falls to the condenser 3 in the lower heat exchange chamber 23 by means of the appropriate drains placed in the separator plate 21 to increase the heating efficiency of the condenser Referring to the regulators mentioned above, they are in the form of covers or shovels to regulate the opening of the air flow in accordance with the control of a controller (not shown). The first regulator 31 is arranged between the evaporator 2 and the discharge port 11 on the inner side and thus constructed to regulate the flow of air between them. Similary, a second regulator 32 is disposed between the condenser 3 and the discharge door 11 on the interior side. And, the third regulator 33 is arranged between the inside door on the inside side of the sill 2, the fourth regulator 34 between the inlet side 12 of the inner side and the condenser 3, the fifth rider 35 between the door from the outer side 14 and the evaporator 2, the sixth regulator 36 between the inlet door of the outer side 14 and the conaenser 3, the seventh regulator 37 between the discharge door of the outer side 13 and the operator 2, and The eighth retainer 38 between the discharge door on the outer side 13 and the condenser 3. In the discharge port of the inner side 11 there is a stacker 10a and in the discharge port of the outer side 13. another blender 10b is arranged. The support of a compressor number 4 and the number 5 shows an expansion valve, which can however be replaced by a capillary tube of a small capacity. They are connected to a refrigerant tube 9 to form a conventional refrigeration cycle. Between the entrance doors of the inner and : x t e r i o r 14 the regulators together 33 and 34 or 35 and 36 are placed the filters 15. The compressor 4 mentioned above can be installed outside the body 1 depending on its capacity. The operation in the chiller function for the aforementioned arrangement according to the invention will be described with reference to Figure 2. Here, the air flow path shown as a dotted line represents the flow of air through the condenser 3 under the separator plate 21. When the regulators 31 and 33, which are placed between the internal route of the air and the evaporator 2, and the regulators 36 and 38, which are placed between the route XI The outside of the air and the condenser 3 are open, while the rest of the regulators 32, 34, 35 and 37 are closed, the hot air in the fl ow room comes from the inlet door of the inner side 12 towards the evaporator 2, where it is cooled, and then the air in a ripple enters the room through the discharge side door 11. On the other hand, the external air which has been introduced through The inlet door 14 absorbs heat as it passes through the co-condenser 3 and is brought out through the discharge door on the outer side 13, so that the cooling of the room is accomplished. In the case of the cooling function, for example, opening the opening of the open regulators 31, 33, 36 and 38 is about 70% and that for the previously closed regulators 32, 34, 35 and 36 they are adjusted to 30%, then 70% of the cold indoor air and 30% of the hot outdoor air for ventilation will pass through the evaporator 2 to result in a mixture of 1 * fresh and cooled air which is supplied to the room. At the same time, the condensed water is produced in the evaporator 2 and then diffused in the condenser 3, which improves the thermal efficiency of the condenser. In other words, the cooling action of the condenser is conducted in combination through the cooled air and the cooled water. The low temperature of the air mixture consists of 70% warm external air and 30% of the internal cold air which flows through the condenser 3 contribute to the increase in heat efficiency to remove the heat from the condenser. In the case of the heating function co or the one shown in Figure 3, in contrast to the following, the regulators 32 and 34 located between the internal air path and the condenser 3 and the regulators 35 and 37 located between the path of The external air and the evaporator 2 are open, while the rest of the regulators 31, 33, 36 and 38 are closed. Thus, the internal circulation of the air is caused by the fan 10a to flow from the inner air intake port 12 through the sizer 3 to be calibrated and thus return it to the room earlier through the internal air discharge door 11. On the other hand, the external air from the external air inlet port 14 is sucked by the fan 10b to flow through the evaporator 2, where the air discharges heat, to be sent to the outside atmosphere through the external air discharge door 13, and thus the heating cycle of the room is completed. In such a heater function, if the regulators 32, 34, 35 and 37 are set to be opened about 70% instead of fully open and the set of regulators 31, 33, 36 and 38 are partially open around the 30% instead of completely closing, 70% of the interior hot air and 30% of the outside cold air for ventilation would pass through the head 3 and will be heated here, and that a mixture of fresh air and hot air can be his inistrado to the room. The heated air mixture consisting of 70% cold outside air and 30% warm indoor air could be supplied to the evaporator 2 and therefore the capacity or efficiency of removing heat from the evaporator would be increased due primarily to the large difference of temperatures. Now another embodiment of the invention will be described with reference to Figures 4 and 5. As seen in the figures, the room. R is provided with a humidity detector ~? and here there is additionally installed a reheater 6 between the interior air discharge door 11 and the evaporator 2. Specifically, this reheater 6 is an auxiliary condenser, which is connected between the condenser 3 and the expansion valve 5, as described in Figure 5. In addition, a hurricane 8 is installed between the interior air discharge door 11 and the condenser 3. The number 41 shows an accumulator, the 42 shows an oil separator, the 43 shows a dryer funnel, 44 and 45 show the solenoid valves, for which the detailed explanation is omitted because they are _components used in a refrigeration cycle. The arrangement construed as mentioned above is thus operated in the cooler function that the heat emission from the condenser 3 or the coolant is regulated by the air flow control of the condenser fan 10b located in the cooling door. external discharge 13 in response to the variation in current relative humidity detected by the age detector 7. Consequently, the heat contained in the refrigerant fluid flowing through the reheater 5, which is connected to the capacitor 3, it is varied tai to appropriately adjust the temperature of the air flowing from the evaporator 2 to the internal air discharge port 11 by the heat emitted from the superheater 6 to result in the relative humidity of the room. In that- id In the meantime, the refrigerant capacity would need to be increased with the increase in the amount of reheat, but the refrigerating capacity would increase because the refrigerant entering the expansion valve 5 would be cooled more corresponding to the increase in reheat, by which does not result in the cooling capacity drop due to overheating. If the relative humidity in the room is below the set value, this can be matched by decreasing the temperature through the normal chiller operation. And when the age detector has detected that the internal relativity is below the value set in the heating function, a humidifier 8 is operated to increase the humidity of the air leaving the condenser 3 to the temperature control port. indoor air discharge 11. When the relative humidity in the room is above the set value, a normal heating operation will be necessary to reduce it.

The opening regulation of the regulators 31 to 38, the operation of the superheater 6 and the humidifier 8, the flow range of the fan 10a or 10b or the heater, as mentioned above, is naturally driven by a controller (not most depending on the age detector 7 to detect the indoor humidity, or temperature detector which is not shown, and the default values introduced optionally by the user. . The number 46 - shows a humidity controller which can be a part of the controller or a separate unit. As clear as mentioned above, the air conditioner for coiling the cooler and heater according to the present invention, the device in which it is a new construction based on a regular refrigeration cycle, can be operated interchangeably to to cool or to heat and with high efficiency optional for full opening or closed c, or regulating the opening for the flow of the air inlet or outlet, 13 or controlling the direction of air flow. In addition, the superheater and the humidifier added in a cooling cycle with encional have a precise regulation and the maintenance of the interior temperature and humidity without additional devices.
