Description

Power saving air conditioner with hot water heater {AIR CONDITIONER EQUIPPED WITH HEATER CIRCULATING BOILED WATER}

The present invention relates to an air conditioner, and more particularly, to a power-saving air conditioner capable of keeping the indoor temperature at a constant temperature by efficiently heating air with low power consumption even in cold weather. .

Air conditioners are classified into various categories, such as whether the outside air is sucked in, the cooling method (air-cooled and water-cooled) of the heat dissipation capacitor, whether the evaporator is separated from other refrigeration cycles, or the installation position relative to the room.

In particular, the present invention is to install an evaporator, a heater, a reheat condenser, etc., inside a housing that can be installed on the floor of the room by a mouth, a compressor, an oil separator, a fluid A receiver, an accumulator, or the like is installed in the housing or the outdoor unit in the room, and on one side of the housing, after installing a duct through the wall to inhale the outside air, the outside air The present invention relates to an external air circulation type air conditioner that sucks and heats or chills according to a set temperature, and sends the same to a room.

In general, the air conditioner is provided with a hot gas controller (hot gas controller) to detect if the temperature of the room (room) is more than the error range than the set temperature to automatically cool or heating. If necessary, the dehumidification function may be performed.

In addition, the inside of the air conditioner is provided with a heat transfer heater is used for heating, such as winter. Recently, in order to reheat the air cooled during the dehumidification process, a re-heating condensor is provided inside the housing separately from the heat dissipation capacitor of the outdoor unit. In the case of dehumidification, the compressor-reheat capacitor is not used. -Dehumidification in the evaporator by refrigerant circulation to the evaporator-compressor and then reheated to the temperature before dehumidification in the reheating capacitor. However, during a heating operation other than the dehumidification operation, the refrigeration cycle is stopped and only the heat transfer heater is operated to suck outside air by the blower and heat the same.

However, such electric heat heater type heating takes a long time to reach the set temperature, in particular, in the outdoor air circulation type air conditioner, there is a problem that the room temperature is difficult to reach the set temperature in the cold weather.

In a conventional air conditioner, cooling is performed by circulating a refrigerant according to a normal refrigeration cycle. In the refrigeration cycle, a refrigerant separates oil from a compressed gas refrigerant and a compressor that compresses a gaseous refrigerant at a high temperature / high pressure. Oil separator to return to the compressor, heat dissipation condenser (outdoor unit) to convert the high temperature / high pressure gas refrigerant, which is installed in the outdoor and is compressed by the compressor into the liquid refrigerant of normal temperature / high pressure, and flows into the evaporator, from the outdoor unit to the liquid state Receiving and storing phase-changed refrigerant to the evaporator, the filter dryer to filter foreign matter from the liquid refrigerant flowing into the evaporator, and the liquid refrigerant at room temperature / high pressure is dropped before the liquid evaporator enters the evaporator. Expansion valve, expanded refrigerant that converts into liquid refrigerant at room temperature / low pressure Distributors distributed to each pipe of the evaporator, vaporizing the incoming refrigerant while taking the latent heat of the air passing through the surroundings, and evaporator that cools the air, and vaporizes the unaccumulated refrigerant to the compressor by circulating sequentially Absorbs heat from the air.

The condenser allows the heat of the high-temperature / high-pressure gas refrigerant from the compressor to exchange heat with the ambient air, thereby making a liquid / refrigerant at room temperature and high pressure, and thus can be used to heat the ambient air in a closed space. The above-mentioned reheating capacitor performs this function.

Another object of the present invention is to provide an air conditioner having a structure capable of minimizing power consumption during heating and dehumidification operation.

Features of the present invention is to make the evaporator 149, the reheat condenser 131 and the hot water radiator 409 in the form of a plate, the evaporator 149, the reheat condenser 131 and from the duct 104 side for introducing the outdoor air The hot water radiator 409 is installed in sequence without being spaced apart, and all the air passing through the evaporator 149 passes through the reheat condenser 131 and all the air passing through the reheat condenser 131 passes through the hot water radiator. To pass through (409). This will not only allow the air cooled by passing through the evaporator 149 during the dehumidification operation to be immediately introduced into the reheating capacitor 131 to be effectively reheated immediately, but also in the reheating capacitor 131 during the heating operation during cold weather. The heated air is immediately reheated in the hot water radiator 409, allowing the room temperature to be raised to a set temperature in a short time.

In addition, another feature of the present invention is a hot gas that can directly inject the hot gas of the high temperature and high pressure compressed in the compressor 109 between the distributor 147 and the compressor 109 of the evaporator 149 directly to the evaporator 149.

And heat radiation of the hot water radiator 409 can be selectively or simultaneously used. The hot gas high pressure gas of the compressor 109 by the hot gas input pipe 123 does not pass through the condenser 131, 301, the receiver 139, and the expansion valves 145, 146, but directly to the evaporator 149. Can be committed.

To this end, the heat dissipation capacitor input tube 119, the reheating capacitor input tube 129 and the hot gas input tube 123 is provided with a solenoid valve (117, 121, 127), a temperature sensor that can measure the room temperature In accordance with the output value of 105, it is preferable to include a control unit 107 for selectively opening and closing the solenoid valves 117, 121, 127. The controller 107 may be configured to control the outdoor unit 300, the hot water heater 400, the damper 102 and the rod heater 161 according to the operating conditions.

In the present invention having the above-described configuration, the cooling operation of the air conditioner opens only the solenoid valve 117 of the heat dissipation capacitor input tube 119 and the compressor 109-> oil separator 113-> heat dissipation capacitor 301-> Refrigerant via fluid receiver (139)-> filter drier (143)-> expansion valves (145, 146)-> distributor (147)-> evaporator (149)-> accumulator (153)-> compressor (109) By a cyclic cycle. In some embodiments, the oil separator 113 or the accumulator 153 may be omitted. The same applies to the circulating cycles of other operations.

In the present invention, the dehumidification operation of the air conditioner opens only the solenoid valve 127 of the reheating capacitor input pipe 129 and the compressor 109-> oil separator 113-> reheating capacitor 131-> receiver 139. -> Filter dryer (143)-> expansion valve (145, 146)-> distributor (147)-> evaporator (149)-> accumulator (153)-> by compressor refrigerant circulation via compressor (109) . At this time, dehumidification is performed in the evaporator 149, and the reheat capacitor 131 reheats the cooled air while passing through the evaporator 149 to the set temperature value.

In the present invention, the heating operation of the air conditioner is performed in multiple stages.

First, heating is performed by driving the rod heater 161 and the blower 201 at the initial heating operation (room temperature below 10 ° C.), but in order to heat the room temperature to 16 ° C. or more within a short time, the reheating capacitor input is performed. Open the solenoid valve 127 of the pipe 129 and the solenoid valve 121 of the hot gas input pipe 123, and open the compressor 109-> oil separator 113-> reheat condenser 131-> receiver ( 139)-> filter drier 143-> expansion valves 145 and 146-> distributor 147-> evaporator 149-> accumulator 153-> compressor 109 and a compressor cycle (109)-> Oil Separator (113)-> Distributor (147)-> Evaporator (149)-> Accumulator (153)-> Compressor 109 to allow the circulation cycle of the compressor to be simultaneously formed. In this process, the air volume of the blower 203 is controlled at a low speed to increase the condensation pressure of the reheating capacitor 131 to 22 Kg / m 2, and to bring the discharge air temperature to around 38 ° C. As a result, the gaseous refrigerant of the high temperature and high pressure and the liquid refrigerant of relatively high temperature and pressure are introduced into the evaporator of the evaporator 149 to increase the evaporation pressure and temperature and heat the inlet air in the entire refrigerant circulation process. Will bring.

In the cold season, not only is it difficult to raise the room temperature to the set temperature within a short time by the circulation of the rod heater 161 or the hot gas, but also it is difficult to continuously supply the amount of heat required for heating. In particular, in the outdoor circulation type air conditioner that sucks outdoor air in a very low temperature state and supplies it to the room, a heating means other than heating by the rod heater 161 or hot gas circulation is required. The present invention is to further heat the air passing through the reheat capacitor 131 by the hot water radiator 409. To this end, the water supply valve 403 of the inlet pipe 405 is opened, and the hot water is circulated to the pump 415 while operating the hot water boiler 401. The hot water introduced into the water inlet pipe 405 heats the air while flowing through the hot water coil 407, is recovered to the hot water boiler 401 through the water outlet pipe 411, and is heated again.

The heating by the hot water radiator 409 may be performed in parallel with the heating by the rod heater 161 or the hot gas circulation, or may be performed alone. As described above, since the reheating capacitor 131 and the hot water radiator 409 are installed in contact without an intermediate gap, the heating by the hot water radiator 409 is performed in parallel with the heating by the rod heater 161 or the hot gas circulation. In this case, since the air heated primarily in the reheating capacitor 131 is introduced into the hot water radiator 409 without heat loss, effective heating can be achieved.

According to the present invention, sufficient heating is possible even in cold weather, the set temperature can be reached in a short time, the power consumption can be minimized during heating and dehumidification operation, and the outdoor air can be efficiently heated without heat loss. There is an advantage to this.

As described above, the power saving type air conditioner having the hot water heater according to the present invention has been described by the embodiment shown in the drawings, but the scope of the present invention is not intended to be limited thereto, and the protection scope of the present invention is defined in the utility model registration claims. It should only be decided by what has been stated.
