The present invention relates to a stationary air conditioner such as, for example, a heating and cooling device for a house and a heating and cooling device for a factory.

Background Art Conventionally, an air conditioner that cools and dehumidifies indoor air with a cooler and heats the cooled air by a heater to perform a dehumidification operation without lowering the room temperature has been proposed. In addition, in the dehumidification operation described above, the indoor humidity is controlled to be the target humidity, and after reaching the target humidity, the dehumidification operation is repeatedly performed to stop the operation and maintain the target humidity.

However, in such a dehumidification operation of the prior art, the humidity detected by the humidity sensor is prioritized, and therefore the cooler is detected so that the indoor temperature is detected by the temperature sensor during the dehumidification operation so that the indoor temperature is close to the set temperature set by the indoor temperature setter. And even if the heater temperature is too high from the set temperature or the cold temperature is too low from the set temperature, if the humidity of the room is close to the target humidity operation time of the dehumidification operation is very short, so the room temperature There was a problem that the temperature was rarely close to the set temperature.

SUMMARY OF THE INVENTION An object of the present invention is to provide an air conditioner capable of quickly approaching a room temperature to a set temperature while maintaining good air conditioning feeling.

The present invention provides a blow casing for blowing air into a room, dehumidifying means disposed in the blow casing to cool and dehumidify the air flowing in the blow casing, and disposed downstream of the dehumidifying means in the blow casing. Heating means for heating the air flowing in the air blowing casing, instructing means for instructing a dehumidifying operation mode for operating the dehumidifying means and the heating means during operation, a temperature detecting means for detecting an indoor temperature, and a humidity detection for detecting an indoor humidity Means, a temperature setting means for setting an indoor temperature, and a humidity setting means for setting an indoor humidity, wherein the indicating means, the temperature detecting means, the humidity detecting means, the temperature setting means, and the humidity setting means are output to the output. Therefore, the dehumidifying means and the heating means is provided with a control means for controlling the operation of the stop.

When the dehumidification operation mode is instructed, the control means includes the dehumidification means when the room temperature detected by the temperature detection means rises above the first reference temperature higher than the set temperature set by the temperature setting means. It only works.

The control means may be configured when the dehumidification operation mode is instructed, when the indoor temperature falls below a second reference temperature lower than the set temperature, or between the first reference temperature and the second reference temperature. When the indoor humidity detected by the humidity detecting means rises above the set humidity set by the humidity setting means, the dehumidifying means and the heating means are operated.

In addition, the control means is dehumidified when the indoor humidity is lower than the set humidity while the indoor air temperature is maintained between the first reference temperature and the second reference temperature when the dehumidification operation mode is instructed. It stops the operation of the means and the heating means.

When the dehumidification operation mode is instructed by the indicating means, the control means inputs the output of the temperature detecting means and the temperature setting means.

When the room temperature detected by the temperature detecting means rises above the first reference temperature higher than the set temperature set by the temperature setting means, the control means operates only the dehumidifying means regardless of the output of the humidity detecting means and the humidity setting means. Let's go. The air flowing in the blowing casing is then cooled by the dehumidifying means and blown into the flesh after being dehumidified. Because of this, the room is dehumidified and cooled, so the room temperature quickly drops to the set temperature.

In addition, when the room temperature falls below the second reference temperature lower than the set temperature, the control means operates the dehumidifying means and the heating means irrespective of the output of the humidity detecting means and the humidity setting means. Then, the air flowing in the blowing casing is cooled by the dehumidifying means and dehumidified, and then heated by the heating means and blown into the room. For this reason, the dehumidification heating operation is performed indoors, so that the indoor temperature is quickly set to the set temperature.

In addition, when the indoor temperature is between the first reference temperature and the second reference temperature, the control means inputs the output by the humidity detecting means and the humidity detecting means.

Then, when the indoor humidity detected by the humidity detecting means rises above the set humidity set by the humidity setting means, the control means operates the dehumidifying means and the heating means. Then, the air flowing in the air blowing casing is cooled by the dehumidifying means, dehumidified, heated by the heating means, and blown into the room. Therefore, the indoor humidity is normally approached to the set humidity because the indoor dehumidification operation is performed.

In addition, when the indoor humidity drops below the set temperature, the control means stops the operation of the dehumidifying means and the heating means, and therefore, the dehumidification is not excessive.

According to the present invention, when the indoor temperature is near the set temperature, the indoor humidity can be properly maintained, and when the indoor temperature is significantly different from the set temperature, the indoor temperature can be quickly approached to the set temperature. As a result, the unpleasant state of the room can be quickly eliminated to make the room a comfortable air-conditioning space.

EMBODIMENT OF THE INVENTION Hereinafter, the air conditioner of this invention is demonstrated based on the Example shown to FIG. 1 thru | or FIG.

1 to 4 are diagrams showing a first embodiment of the present invention, in which FIG. 1 is a block diagram showing a control circuit of a heating and cooling device, and FIG. 2 is a schematic diagram showing a heating and cooling device.

The air conditioning and heating device 1 according to the present invention includes a blower casing 2, a blower 3, a refrigeration cycle 4, a hot water heater 5, and a control circuit 6, and an indoor unit 7 in which they are arranged indoors. ) And an outdoor unit 8 arranged outdoors.

The blowing casing 2 is disposed in the indoor unit 7, and has an inlet 21 for suctioning indoor air at one end and a spout 22 for ejecting air conditioning air at the other end.

The blower 3 is disposed in the blow casing 2, and when energized, generates an air flow toward the inside of the blow casing 2.

The refrigeration cycle 4 is a well-known structure and consists of the refrigerant | coolant compressor 41, the refrigerant | condenser condenser 42, the refrigerant | vaporizer 43, and the refrigerant pipe 44 which connects them in an annular shape. The refrigerant condenser 42 condenses the refrigerant by heat-exchanging the introduced refrigerant with the air blown out by the fan 46. The refrigerant evaporator 43 is a dehumidifying means of the present invention. The refrigerant evaporator 43 exchanges heat with the introduced refrigerant and the air flowing in the air blowing casing 2 to evaporate the refrigerant and to cool and dehumidify the air.

The hot water heating device 5 is configured as air, and the gas burner 51 and the heat exchanger 52 heat the hot water by heat-exchanging the combustion heat of the gas burner 51 and the hot water flowing therein. The hot water heater 53 is a heating means of the present invention, and heats the air by heat-exchanging the flowing hot water and the air flowing in the blowing casing 2. When the electric pump 54 is energized, a circulation flow is generated in cooling the hot water circuit 55.

The control circuit 6 is blower according to the output of the operation switch 60, the operation switching switch 61, the room temperature sensor 65, the humidity sensor 66, the temperature setter 67 and the humidity setter 68. (3), the energization of the electric motor 45 and the electric pump 54 and the stop of energization are controlled, and the ignition mastication of the gas burner 51 is performed.

The operation switch (60) is a start switch of the air conditioning and heating device (1). When it is turned on, the operation switch (60) connects the power supply and each electric device. The operation switching switch 61 is an indication means of the present invention, and when the air conditioning operation 62 is selected, the air conditioning mode is switched to the air cooling operation mode, while when the heating operation 63 is selected, the air conditioning mode switches the heating operation mode. When the dry operation switch 64 is selected, the air conditioning mode is switched to the dry operation mode. The temperature sensor 65 is a temperature detecting means of the present invention, which is disposed in the inlet 921 of the blow casing 2, detects the room temperature, converts the detected value into an electrical signal, and transmits it to the control circuit 6. The temperature setter 67 is a temperature setting means of the present invention, and it is possible to set the room temperature to an arbitrary temperature, and converts the set set temperature into a low signal and transmits it to the control circuit 6. Humidity setter 68 is a humidity setting means of the present invention, it is possible to set the room temperature to an arbitrary humidity, and converts the set set humidity into an electrical signal to transmit to the control circuit (6).

3 and 4 are operation flowcharts showing the operation in the dry operation mode of the control circuit 6 of this embodiment, and the movement flowchart is performed when the operation switch 60 is turned on. First, it is judged whether or not the dry operation 64 is selected (step S1). When the dry operation 64 is NO, the control of step S1 is performed, while the dry operation 64 is performed in step S1. If Yes is selected, the blower 3 is operated (tm step S2), and the hot water heating device 5 and the refrigeration cycle 4 are operated (step S3). For example, if 2 minutes) has elapsed (Step S4), and if NO for which the predetermined time has elapsed, the control of Step S4 is performed, whereas if Yes after predetermined time has elapsed for Step S4, the indoor temperature is the set temperature. For example, it is judged whether it has risen above the 1st reference temperature as high as +1 degreeC (step S5). As a result of the determination, in the case where the room temperature rises above the first reference temperature, the hot water heater 5 is stopped (step S6), and then the control of step S5 is performed.

If the indoor temperature is NO in which the indoor temperature is not raised above the first reference temperature in step S5, it is judged whether or not the indoor temperature is lowered below the second reference temperature, which is lower by, for example, -1 ° C, than the set temperature ( Step S7) When the indoor temperature is Yes, which is lower than the second reference temperature, the control of step S5 is performed.

On the other hand, if the indoor temperature is NO which is not lower than the second reference temperature or less in step S7, it is determined whether the indoor humidity is lower than or equal to the set humidity (step S8) (FIG. 4), and the indoor humidity is When NO is not lowered below the set humidity, control of step S5 (FIG. 3) is performed.

In step S8, if the indoor humidity is lower than the set humidity, the hot water heating device 5 and the freezing cycle 4 are stopped (step S9), and then a predetermined time (for example, 3 minutes) It is judged whether this has passed (step S10). As a result of the determination, in the case of NO in which the predetermined time has elapsed, the control of the stainless S10 is performed again.

In the case of Yes when the predetermined time has elapsed in step S10, it is determined whether the predetermined time (for example, 2 minutes) has elapsed after the operation state is the same as that before the refrigeration cycle 4 stops in step S9 (step S11). (Step S12), if NO for a predetermined time has not occurred, then control of Step S12 is performed again.

In the case of Yes when the predetermined time has elapsed in step S12, control of step S5 (FIG. 3) is performed.

The control method in the dry operation mode of this air conditioning apparatus 1 is demonstrated based on FIG. 1, FIG. 2, and FIG.

The control furnace 6 first reads the room temperature from the room temperature sensor 65 and the room temperature from the temperature setter 67 when the dry operation mode is instructed.

A) When the room temperature rises above the first reference temperature

When the blower 3 and the electric motor 45 are energized by the control circuit 6 to drive the coolant compressor 41 to supply the compressed refrigerant to the coolant evaporator 43, the blower casing (3) 2) The indoor air sucked in is exchanged with the refrigerant flowing through the refrigerant evaporator 43 to cool and dehumidify. Since the dehumidified air does not have hot water flowing in the hot water heater 53, the dehumidified air is blown into the room from the jet outlet 22 without being heat-exchanged in the hot water heater 53. As a result, the indoor temperature decreases rapidly toward the set temperature.

B) When the room temperature is lower than the second reference temperature

When the gas burner 51 is burned by energizing the blower 3, the electric motor 45, and the electric pulp 54 by the control furnace 6, the air flowing in the blow casing 2 is a refrigerant evaporator 43. It dehumidifies by heat-exchanging and cooling with the refrigerant which flows inside. On the other hand, the gas burner 51 supplied with the buty combustion gas to the gas supply passage 56 heats the hot water flowing in the heat exchanger 52, and the heated hot water is applied to the pressure force of the electric pump 54. It flows into the warm water type | mold heater 53 by this. Therefore, the air dehumidified when passing through the refrigerant evaporator 43 is heated as it is heat-exchanged with the hot water flowing in the hot water heater 53, and is discharged from the jet port 22 into the room. For this reason, as shown in FIG. 4, the room is dehumidified and heated, and the room temperature rapidly rises toward the set temperature.

C) When the room temperature is between the first reference temperature and the second reference temperature

The control circuit 6 reads the set humidity from the humidity setter 68 together with the read indoor humidity from the humidity sensor 66.

When the indoor humidity is higher than the set humidity, the above-mentioned control shown in FIG. 4 is performed. Therefore, the indoor temperature and the indoor humidity are determined according to the set temperature and the set humidity. Normally, the dehumidification operation causes the room temperature and the room humidity to be close to the set temperature and the set humidity.

In addition, the control circuit 6 stops energization of the electric motor 45 and the tumble pump 54 for a predetermined time while stopping the combustion of the gas burner 51 when the indoor humidity is lowered below the set humidity. In addition, the refrigerant compressor 41 is also stopped. Then, even though the air flowing in the blower case 2 passes through the refrigerant evaporator 43 and the hot water heater 53, the air is blown out without being dehumidified and heated. Therefore, the room is not excessively dehumidified. In addition, the control circuit 6 forcibly resumes operation in the same dehumidification operation mode as before the stop, irrespective of the room temperature and the room humidity after a predetermined time has elapsed.

As described above, in the present embodiment, by performing air conditioning on humidity only when the indoor temperature is between the first reference temperature and the second reference temperature, the indoor temperature can be quickly approached to the set temperature, and also the indoor humidity. Can be maintained appropriately. Therefore, the unpleasant state of the room, that is, the humid state, can be quickly eliminated, and the room can be made a comfortable air-conditioning space.

FIG. 6 is a view showing a second embodiment of the present invention, that is, an operation flowchart showing the operation during the dry heating operation of the control circuit 6, in which the same control as in the first embodiment is given the same reference numeral and is duplicated. General description will be omitted.

After the control of step S6, it is determined whether the room temperature has reached the set temperature (step S21), and if the room temperature is NO that has not reached the set temperature, control of step S6 is performed again, while step S21 In step S8, when the room temperature reaches Yes when the set temperature is reached, the control of step S8 is performed.

After the control of step S7 is performed, it is determined whether the room temperature has reached the set temperature (step S22), and if the room temperature is NO that has not reached the set temperature, the control of step S22 is performed again, while the staff If S22 is Yes when the room temperature reaches the set temperature, control of the stainless S8 is performed.

As described above, in the air conditioner 1 according to the present embodiment, when the room temperature falls from the first reference temperature or more or when the room temperature rises below the second reference temperature, the room temperature reaches the actual temperature. The reading of the humidity and the actual humidity, that is, the normal dehumidification operation mode is started.

In addition, according to a modification of the present embodiment, although a refrigerant decanter of a refrigeration cycle is used as the dehumidifying means, a semiconductor cooling element such as a body element may be used as the dehumidifying means, and in this embodiment, it is turned on as a heating means. Although a modified heater is used, an electric heater may be used as the heating means.
