The present invention relates to a hybrid power saving dehumidifying apparatus, and more particularly, to a hybrid power saving dehumidifying apparatus for supplying heat by converting air according to the indoor working environment.

In general, heat cannot itself move from a low temperature to a high temperature, and the heat transfer necessarily takes work. Just as a pump is a machine that pumps water from a low position to a high position, a heat pump is a device that can transfer heat from a low temperature to a high temperature.

The configuration and operation method of the heat pump cycle is the same as that of a freezer, which is a freezer only for the purpose of using low temperature heat, and a heat pump for the purpose of using the high temperature heat.

In addition, heat pumps are classified into compression type, chemical formula, absorption type, and absorption type according to the classification of the principle of absorbing heat and radiating heat. Among them, the type of heat pump is a compression type heat pump.

Here, the compression type heat pump may be considered as a reverse cycle of a cooling apparatus called an air conditioner. In other words, the air conditioner for cooling is the principle of absorbing heat from the heat exchanger of the indoor unit installed indoors and using the heat exchanger of the outdoor unit installed outdoors to radiate heat from the inside to the outside. It is a principle of heat dissipation of heat absorbed outdoors by using heat exchanger of indoor unit installed in indoor.

At this time, the basic components of the compressed heat pump cycle are divided into four elements, evaporator, which is a low temperature heat exchanger, a condenser, which is a high temperature heat exchanger, and an expansion valve. . The low-temperature low-pressure wet steam refrigerant evaporates in the evaporator, absorbs latent heat of evaporation, and is discharged into the low-temperature, low-pressure dry saturated steam refrigerant evaporated. The refrigerant in the low temperature low pressure dry saturated vapor state discharged from the evaporator is adiabaticly compressed by the compressor and becomes a refrigerant in the high temperature high pressure superheated steam state and flows into the condenser.

Here, the high temperature and high pressure superheated steam introduced into the condenser releases latent heat of condensation and becomes a refrigerant in a saturated liquid state at high temperature and high pressure and flows into the expansion valve. Saturated liquid refrigerant at high temperature and high pressure expands isoenthalally at the expansion valve and flows into the evaporator as the refrigerant at low temperature and low pressure.

In general, an evaporator, which is a low temperature heat exchanger, is installed outdoors, and is installed inside a condenser that is a high temperature heat exchanger. The low temperature evaporator is installed outdoors to absorb heat from the surroundings (called a heat source, and a lot of air is commonly used in homes), and the high temperature condenser is installed indoors to release heat to the surroundings (called heat sinks). It is applied a lot).

And, by combining the heat pump and the refrigerator can be configured an air conditioner that can control the temperature and humidity of the indoor air.

However, conventional air conditioners have a problem in that energy efficiency is not good and moisture is not properly removed from the air flowing into the room.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide an air conditioner having the advantage that the energy efficiency is high and dehumidification is properly performed in the air.

The hybrid energy-saving dehumidifying apparatus according to the present invention for solving the above problems is a compressor in which the refrigerant is introduced and compressed, an outdoor heat exchanger in which the refrigerant of the compressor is introduced, heat exchange with the outside by a fan, and the outdoor An expansion valve that expands as the refrigerant passing through the heat exchanger flows, and a plurality of evaporators for cooling the air flowing into the room by the introduction of the refrigerant passing through the expansion valve, and air disposed on one side of the evaporator and cooled by the evaporator The refrigerant passing through the compressor and the predetermined capillary to remove moisture from the outdoor heat exchanger and absorbing the heat from the outside air to heat the air flowing into the room through the evaporator and the refrigerant passing through the compressor and the capillary. An indoor heat exchanger optionally supplied to the evaporator or the indoor heat exchanger Cooling operation for supplying the air cooled by the fan in the blower for supplying the heat-converted air into the room and the refrigerant cooled by the fan in the outdoor heat exchanger and expanded by the expansion valve to the evaporator And a dehumidifying operation of supplying the air having moisture removed from the air passing through the evaporator to the room by the blower by supplying the refrigerant passing through the capillary tube to the indoor heat exchanger in the compressor. Refrigerant flow control means for performing at least one or more of the heating operation for supplying the air heated by the indoor heat exchanger to the indoor heat exchanger by the blower by supplying the refrigerant absorbing the heat of the refrigerant through the compressor to the indoor heat exchanger. .
