冷房作用を行々い、圧縮機すに戻す回路をとっている。Conventionally, the refrigeration cycle used in air conditioners with capacity control is mainly used, as shown in Figure 1, when the capacity is not controlled, the electromagnetic on-off valve a closes and the compressor is closed. The compressed high-temperature, high-pressure refrigerant gas is cooled by passing through the condenser C, the supercooled refrigerant is depressurized by the throttle device d, and the low-temperature, low-pressure gas-liquid two-phase refrigerant is passed through the evaporator e to perform a cooling effect. It has a circuit that returns it to the compressor.

。However, during capacity control operation, the electromagnetic on-off valve a is opened and a portion of the refrigerant gas sucked into the compressor is transferred from the bypass port provided between the discharge boat and the suction boat in the compressor cylinder to the suction pipe. Capacity control is performed by reducing the circulating amount of refrigerant bypassed to f and discharged from the compressor.

の効率を低下させる原因のひとつとなっていた。Then, the bypassed refrigerant gas returns from the evaporator e)
The temperature of the bypassed refrigerant gas is higher than the temperature of the refrigerant gas returned from the evaporator e, so the refrigerant gas is mixed with the refrigerant gas that is mixed and sucked into the compressor. temperature increases. This increases the specific volume of the refrigerant gas sucked into the compressor, which is one of the causes of reducing the efficiency of the refrigeration cycle.

るため説明を省略する。In the figure, 1 is a compressor, 2 is a condenser, 3 is a throttle device, and 4 is an evaporator, which are connected in a ring to form a main refrigerant circuit. As is well known, the compressor 1 includes a bypass port provided between a discharge port and a suction port in the cylinder, and has a structure capable of controlling capacity. 6 (r1 ~ A bypass pipe connects the bypass port and the suction pipe 1N of the compressor 1.6
7 is a double pipe constituting a part of the bypass pipe 6, 8 is a water tray for the evaporator 4, and 9 is a drain hose, as shown in FIG. A water tray 80 is connected to drain water into the double pipe 7. Here, the structural relationship between the evaporator 4 and the water tray 8 is well known as an indoor unit of a separate type air conditioner, so a description thereof will be omitted.

る。In the above configuration, during operation without capacity control, the electromagnetic on-off valve 5 is closed, and the high-temperature, high-pressure refrigerant gas exits the compressor 1 and flows into the condenser 2 as shown by the dotted arrow in FIG. A circuit is formed in which the heat is radiated through the compressor, the pressure is reduced by the throttle device 3, the heat is absorbed through the evaporator 4, and the heat is returned to the compressor 1.

能力が増加する。In operation during capacity control, the electromagnetic on-off valve 5 is opened, and in addition to the above-mentioned circuit, a part of the refrigerant gas sucked into the compressor 1 enters the bypass port, as shown by the solid arrow in the figure. A bypass circuit is formed in which the refrigerant is bypassed from the compressor 1 to the suction pipe, and the amount of refrigerant circulated discharged from the compressor 1 is reduced. At this time, as shown by the dashed-dotted arrow in the same figure, drain water is guided from the indoor water tray 8 to the double pipe 7 with the drain hose 9, and the third
Since the double pipe structure shown in the figure is used to exchange heat between the bypass pipe 6 and the drain water, the refrigerant gas that has been bypassed is cooled. As a result, the humidity of the refrigerant gas mixed with the refrigerant in the main refrigerant circuit and sucked into the compressor 1 decreases, the specific volume decreases, the amount of refrigerant circulated increases, and the cooling capacity increases.

まり変化せず、効率が向上する。Figure 4 shows the relationship between bypass pipe cooling amount, main unit cooling capacity, input, and efficiency. As is clear from the figure, as the bypass pipe cooling amount increases, the cooling capacity increases, but the input does not change much, and the efficiency improves.
したがって、同一人力に対して高冷房能力が得られ、効
率の高い冷凍サイクルとなる。Therefore, a high cooling capacity can be obtained with the same human power, resulting in a highly efficient refrigeration cycle.

価であるなど、種々の利点を有するものである。A main circuit of the refrigeration cycle is constructed by sequentially connecting a throttling device and an evaporator, and a bypass port is provided between the discharge port and the suction port in the cylinder of the compressor that constitutes this main circuit. A bypass circuit was installed to connect the suction pipes of the compressor, and a part of this bypass circuit was made into a double pipe structure, so that the drain water led from the indoor water pan was made to flow through the double pipe as shown on page 6. Since the refrigerant gas that is bypassed is cooled by drain water, the specific volume of refrigerant gas taken into the compressor can be reduced, reducing the decrease in efficiency of the refrigeration cycle during capacity control, and drain water Since the cooling is performed using the cooling part, the structure of the cooling part is simple and inexpensive, and has various advantages.
