The present invention relates to a air conditioning and heating device equipped with a small air conditioning room and a total heat exchanger, and more particularly, it is possible to control waste by recovering waste heat by total heat exchange to minimize heat loss and at the same time branching into multiple spaces through a single distributor. The present invention relates to a small air conditioner and a total heat exchanger to maximize a thermal efficiency by forming a small air conditioning room.

Heat transfer mechanisms are generally classified into heat conduction, convection, and heat radiation. In particular, heat conduction is energy of thermal movement from the hot part to the cold part of an object without moving material through lattice vibration / conducting electrons. Is a phenomenon of transfer and movement.

On the other hand, the density of fluid (gas or liquid) is changed by the temperature difference, the portion of the lower density rises and the portion of the higher density is lowered, the local circulation of the material occurs. Convection refers to the transfer of heat by the mass flow as described above.

In addition, heat radiation is a heat transfer by heat rays radiating from a solid surface, and is related to heat exchange action, heat retention action, and cooling action.

In particular, the heat exchange action is to transfer the heat energy of the high-temperature fluid to the low-temperature fluid, for example, to effect the heating / cooling / evaporation / condensation through a plate heat exchanger, etc. To be able.

All the heat transfer mechanisms as above can be defined as heat transfer. Heat transfer is the phenomenon in which heat transfer occurs from the high temperature side to the low temperature side. For example, an air conditioner is used to Heat exchanging in the space is achieved to control the room air to the desired temperature.

In addition, the air conditioner as described above is to control the temperature, humidity, cleanliness, average flow rate, etc. of the indoor air, and to remove dust and harmful gases, In summer and winter, cooling and heating (기가, 煖房) may be a combination of cooling and heating units to be made respectively.

According to the configuration of the unit, the air conditioner is roughly classified into an integrated type in which the components constituting the refrigeration cycle are housed in a single case, and a separate type in which the evaporator is an indoor unit and the compressor and the condenser are configured as outdoor units.

As shown in FIG. 1, the refrigeration cycle connects the evaporator 2 installed at the indoor side and the condenser 4 installed at the atmosphere side with the refrigerant pipes 6 and 8, and has one refrigerant pipe ( The compressor 10 is provided in 6), and the receiver driver 12 and the expansion valve V are installed in the other refrigerant pipe 8, respectively.

On the other hand, the evaporator (2) and the condenser (4) by each of the blowing fan 14 and the cooling fan 16 is able to actively perform heat exchange action with the atmosphere.

According to this configuration, the refrigerant present in the evaporator 2, the condenser 4, and the refrigerant pipes 6 and 8 is circulated by the compression force of the compressor 10, and is in a state of being radiated through the condenser 4. The refrigerant is circulated to the evaporator 2.

At this time, a heat exchange action is performed between the air hit by the cooling fins of the evaporator 2 and the refrigerant circulated inside the evaporator 2 by the blower fan 14 of the evaporator 2, whereby the cold air By being supplied indoors, the indoor temperature can be maintained comfortably.

On the other hand, the heat is circulated back to the condenser 4 under an endothermic state due to the heat exchange action of the evaporator 2, wherein air hits the cooling fins of the condenser 4 by the cooling fan 16 of the condenser 4. And heat exchange between the refrigerant circulated in the condenser 4 is made, and thus heat is radiated from the refrigerant in the endothermic state.

In addition, the driving of the solenoid portion of the compressor 10 and the expansion valve V and the blowing fan 14 and the cooling fan 16 may be controlled by the controller C according to the indoor temperature condition.

To this end, the solenoid portion of the compressor 10, the expansion valve V, the blowing fan 14, the cooling fan 16, and a temperature sensor Ts and manipulation means provided to detect an indoor temperature are controlled by the controller.

In addition, such a conventional air conditioner has a structure in which waste heat recovery is impossible when the heating unit is operated. Therefore, a hot exhaust gas is discharged as it is, and the intake air is not preheated, thus causing a problem of wasting energy. .

In addition, the air-conditioning device as described above has a problem in that the air-conditioning is applied only to a space other than the space in which the air-conditioning device is installed, thereby limiting the use of the air-conditioning device.

In particular, when the air-conditioning room is applied to each space (room) by the centralized heating and cooling method, there is a problem of further encouraging heat loss since there is no device for selectively blocking or supplying the heating and cooling heat supplied according to the situation.

For example, when air-conditioning heat is provided for installation in a large number of rooms, it is not possible to selectively block the air-conditioning heat in a small number of rooms according to the user's choice, and also do not adjust the airflow of the air-conditioning heat provided according to the size of the room. As it becomes impossible

Therefore, the main object of the present invention is to enable the heat storage and the pre-heating or pre-heating of the intake air entering the room is possible to accumulate cooling and heat storage, to improve the energy savings.

In addition, another object of the present invention is to provide a heat shield and selectively block the heating and cooling in each space through a small air conditioning room installed in the air distributor in a radial shape a plurality of branch pipes equipped with an automatic damper. .

In addition, another object of the present invention is to install a motor of the heating and cooling system variable motor Burberry motor to prevent the damage of the motor due to the overload so that the air-conditioning device is applied to a high floor to match the pressure difference and the change in outside pressure It's about making it happen.

In addition, another object of the present invention is to apply the material of the air discharge fan 냉 of the air conditioning and heating device from the plastic 휀 to a metal made of aluminum or rolled steel sheet to prevent breakage of the 에 to the outside air pressure 6 of the blade of the blade 휀 The input angle of about 10 ° to 9 ° is set to 10 ° to 14 ° to enable the heating and cooling system to be installed in a large generation for fixed pressure.
