Description

Air conditioner with drain device The present invention relates to an air conditioner equipped with a drain utilization device, and more specifically, to an air conditioner equipped with a drain utilization device capable of effectively treating drain generated from an evaporator when operating a vapor compression type refrigeration device. Generally, an air conditioner is a device designed to vary the temperature of an indoor space through the heat exchange action of a refrigerant that repeatedly performs cycles of compression, condensation, expansion, and evaporation, and is composed of an indoor unit and an outdoor unit, with the exception of portable or window air conditioners. Air conditioners can be classified into portable air conditioners designed to be movable by wheels, window-type air conditioners installed in window frames, room air conditioners and package air conditioners in which indoor and outdoor units are installed separately, and system air conditioners in which multiple indoor units are each installed in a single outdoor unit. The above outdoor unit includes a compressor and a condenser, and generates relatively high-temperature heat during cooling operation, so it is mainly fixedly installed outdoors. The indoor unit includes an expansion valve and an evaporator and is fixedly installed inside an air-conditioned space. The indoor unit discharges cold air into the indoor space through the evaporator. And, the drain generated during heat exchange in the above evaporator is discharged to the outside through a separate condensate pipe. Meanwhile, in conventional fixed split-type air conditioners, the outdoor and indoor units are each placed at fixed locations and connected by piping, forming a structure in which refrigerant circulates. However, in conventional fixed split-type air conditioners, the drain pipe through which the refrigerant piping and the drain generated in the indoor unit travel is also installed, which may result in difficulties in installation, a burden of installation costs, and problems with drain discharge.

Hereinafter, in order to explain in detail enough for a person skilled in the art to easily implement the technical concept of the present invention, embodiments of the present invention will be described with reference to the attached drawings. However, the following examples are merely illustrative to aid in understanding the present invention and do not reduce or limit the scope of the present invention. Furthermore, the present invention may be implemented in various different forms and is not limited to the embodiments described herein. FIG. 1 is a configuration diagram of an air conditioner (1) equipped with a drain utilization device according to the present invention, and FIG. 2 is a diagram of the usage state of an air conditioner (1) equipped with a drain utilization device. Referring to FIGS. 1 and 2, an air conditioner (1) equipped with a drain utilization device according to the present invention comprises a compressor (10), a condenser (11), an expansion valve (12), and an evaporator (13). First, the compressor (10) compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. And, the condenser (11) is connected to the compressor (10) and condenses the high-temperature, high-pressure gaseous refrigerant discharged from the compressor (10) into high-temperature, high-pressure liquid refrigerant. Meanwhile, the low-temperature air passing through the condenser (11) is converted into high-temperature air by the high-temperature, high-pressure gaseous refrigerant and discharged to the outside. And, the expansion valve (12) is connected to the condenser (11) and expands the high-temperature, high-pressure liquid refrigerant discharged from the condenser (11) into low-temperature, low-pressure liquid refrigerant. And, the evaporator (13) is connected to the expansion valve (12) and evaporates the low-temperature, low-pressure liquid refrigerant discharged from the expansion valve (12) into a low-temperature, low-pressure gaseous refrigerant. Meanwhile, the high-temperature air passing through the evaporator (13) is converted into low-temperature air by a low-temperature, low-pressure liquid refrigerant and supplied to the roo
