を目的とする。DETAILED DESCRIPTION OF THE INVENTION The present invention improves the efficiency of a refrigeration cycle by cooling or heating the parts that become high temperature and the part that becomes low temperature during operation, and uses an outdoor heat exchanger as an evaporative heat exchanger. The purpose is to simultaneously reduce the size of air conditioners by using this technology.

増加するなどの欠点を有していた。Conventionally, drain water, which is generated by condensation of moisture in the air on the heat transfer surface of the evaporator of an air conditioner, is guided to a water tray, and a part of the cooling pipe is immersed in the water tray. After cooling, high-temperature drain water is discharged, and after the drain water is collected in a tank, it is sprayed into a condenser via a heat exchanger installed above the compressor using a pump. There was an air conditioner that used drain water. However, in the former case, a treatment device is required to discharge high-temperature drain water, and moreover, the drain water is only used for head heat exchange, and its latent heat of vaporization is not used. Furthermore, in the latter case, since the drain water is guided to a heat exchanger provided above the compressor, the drain water is heated, and even if the drain water is then heated to the condenser, the cooling effect is small.
In addition, there are some pipes that make up the refrigeration cycle that have been designed to improve efficiency by exchanging heat between the high temperature part and the low temperature part; Because it only transfers heat internally, its effect is small, and the parts that perform heat exchange are often far apart, in which case it is necessary to extend the piping.
Therefore, it has disadvantages such as increased heat loss in the extended piping and increased pressure loss due to soot.
本発明は以上のような従来の欠点を解消するものであり
、以下に、その実施例を図面を用いて詳細に説明する。The present invention solves the above-mentioned conventional drawbacks, and embodiments thereof will be described in detail below with reference to the drawings.

Note that 8 is an outdoor blower and 9 is an indoor blower. Further, 10 is a spray nozzle, and liquid is supplied from a liquid pipe 11. This liquid pipe 11 is in a heat exchange relationship with a first heat exchange part 12 which is in a heat exchange relationship with the pipe 4 and with the pipe 2. It has a certain second heat exchange section 13.

り噴霧されて微小液滴となる。When the superheated gas cold soot compressed to high temperature and pressure by the compressor 1 passes through the second heat exchange section 13 of the pipe 2, it exchanges heat with the cold liquid and radiates heat to lower the temperature. It enters the outdoor heat exchanger 3. Here, the cold soot exchanges heat with the outdoor air blown by the outdoor blower 8, and is cooled by using the latent heat of vaporization of the liquid emitted from the spray nozzle 10, and is condensed into a supercooled liquid state. become. Next, this supercooled liquid cold soot passes through the pipe 6, is depressurized and expanded by the expansion device 7, and flows into the indoor heat exchanger 5 in a gas-liquid two-phase state.
Here, the cold soot exchanges heat with the indoor air blown by the indoor blower 91, absorbs heat, cools the room, and evaporates into a state of low-temperature gas cold soot. When this low-temperature gas cold soot passes through the first heat exchange section of the pipe 4, it exchanges heat with the warm liquid, absorbs heat, becomes a superheated gas medium, and returns to the compressor 1. On the other hand, as can be seen from the above explanation, the liquid to be misted from the mist nozzle 10 is supplied from the liquid pipe 11 and is
When passing through the heat exchange section 12, the liquid is cooled to exchange heat with the cold soot of the low-temperature gas, and then the low-temperature liquid passes through the second heat exchange section 13, at which time it exchanges heat with the cold soot of the superheated gas. It is replaced and warmed up, and when it reaches almost the original temperature, it is sprayed from the mist nozzle 10 and becomes minute droplets.

られることは明らかである。These minute droplets form a thin liquid film on the heat transfer surface of the outdoor heat exchanger 3, and by utilizing the latent heat of evaporation when this liquid film evaporates, the heat transfer performance of the outdoor heat exchanger 3 is significantly improved. is improving. FIG. 2 is a cold soot circuit diagram of an air conditioner according to a second embodiment of the present invention, and the same functional parts as in the embodiment of FIG. 1 are designated by the same numbers. The difference between the second embodiment and the first embodiment is that the second heat exchange section 13 is provided in a heat exchange relationship with the pipe 6. Thereby, the liquid cooled by heat exchange between the outlet side pipe 4 of the indoor heat exchanger 5, which acts as an evaporator, and the first heat exchange section 12 of the liquid pipe 11, is transferred to the outdoor side, which acts as a condenser. The heat exchanger 3 is guided to a second heat exchange section 13 provided in a heat exchange relationship with the piping 6 on the outlet side of the heat exchanger 3 . Here, heat is exchanged with the condensed liquid in the outdoor heat exchanger 3, and the degree of supercooling of the refrigerant is increased by absorbing heat. Supplied. Further, in the above embodiment, the liquid pipe 11 was provided with the first heat exchange section 12 and the second heat exchange section to heat and cool the cold soot, but the present invention is not limited to this. It is clear that the same effect can be obtained by providing a liquid reservoir in the section and exchanging heat with this liquid reservoir and parts that become hot and cold during operation.

である。As is clear from the above description, the present invention configures a refrigeration cycle by connecting a compressor, an outdoor heat exchanger, a throttling device, an indoor heat exchanger, etc. During operation, a fogging device is installed to atomize minute droplets into the outdoor heat exchanger through liquid pipes that are in a heat exchange relationship with both the high-temperature and low-temperature parts. Since this air conditioner is characterized by the fact that Furthermore, there is almost no difference in the temperature of the liquid when it is supplied and when it is atomized, so even when it is sprayed onto the outdoor heat exchanger that acts as a condenser, the cooling effect is large and the transmission is This greatly improves thermal performance.

できる。Therefore, the size of the air conditioner can be reduced to the extent that the performance of the outdoor heat exchanger is improved. Further, according to the present invention, there is no need to extend the cold soot piping, and there is no problem of heat loss or pressure loss of cold soot caused by extending the piping. Further, the present invention provides a method for supplying liquid to the misting device through a liquid pipe that is in a heat exchange relationship with both the discharge side and the suction side of the compressor.
The gas cold soot that is sucked into the compressor is superheated by using the sensible heat of the liquid.
Even if unevaporated liquid-cooled soot gets mixed in, such as when the cooling load is 4.5, it can be evaporated, preventing liquid-cooled soot from returning to the compressor and causing malfunctions such as liquid compression. can.

を増加させることができるものである。Furthermore, the liquid cooled by exchanging heat with the gas cooler sucked into the compressor exchanges heat with the high-temperature, high-pressure superheated gas cooler on the discharge side of the compressor, acting as an auxiliary condenser. This makes it possible to downsize the outdoor heat exchanger that functions as a condenser. Furthermore, the present invention provides spraying via liquid pipes that are in a heat exchange relationship with both the outlet side of the outdoor heat exchanger that serves as a condenser and the indoor heat exchanger that serves as an evaporator during cooling operation. Since the device is characterized by supplying liquid to the device, the soot leaving the outdoor heat exchanger exchanges heat with the low-temperature liquid, increasing the degree of supercooling and increasing the cooling capacity. It is something that can be done.
