Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an operation control device for an air conditioner.

[Prior Art] Conventionally, air conditioners have been used that adjust the temperature, humidity, and other air conditions of indoor air to set the air conditions to conditions suitable for human habitation. Examples of this air conditioner include a cooling dehumidifier, a heating device, and the like.

Here, the conventional air conditioner is
As described in Japanese Patent No. 38, an operation control device is provided that maintains the room temperature at a desired set value based on the detection result of the room temperature sensor.

[Problems to be Solved by the Invention] However, in conventional air conditioners, when a room to be air-conditioned is equipped with an opening such as a window or a doorway, air conditioning is performed regardless of whether the opening is opened or closed. The operation of the device is controlled, and there is a risk that thermal energy for air conditioning will escape to the outside space through the open opening, resulting in wasted consumption of that thermal energy.

An object of the present invention is to perform indoor air conditioning under conditions that effectively consume thermal energy.

[Means for Solving the Problems] The present invention provides an operation control device for an air conditioner that adjusts the air condition in a room having an opening, which includes an open/close detector for detecting a closed state of the opening; 1. Under the condition that detects the closed state of the opening. and a controller for operating the air conditioner δ.

[Operation] According to the present invention, the air conditioner is operated on the condition that the opening/closing detector detects the closed state of the opening. That is, the thermal energy exerted indoors by the air conditioner is effectively consumed for indoor air conditioning without escaping to the outside space through the open opening.

2. The heat storage tank 14 is for heat exchange! 23 and 24, a pump 25 and a water heater 26 are also provided. That is, the heat storage device 10 has the compressor 1 of the cooler 11.
5, expansion valve 16, clearance. - Mulator 17, indoor unit 12 heat exchanger 18, outdoor FI 13 heat exchanger 21, heat storage tank 1
A thermal cycle is formed by four heat exchangers 23,24. 27A to 27F are electromagnetic on-off valves.

The heat storage device 10 includes a controller 28 made of a microcomputer or the like. The one device 28 to control is the expansion valve 16, the on-off valve 27A~
27F is switched and controlled to form a heat medium circulation circuit for each operation mode, and the compressor 15, expansion valve 16, and blower 19.22 are drive-controlled to operate the thermal cycle in each operation mode.

Here, each operation mode of the heat storage device 10 will be explained as follows: Cooling/dehumidifying mode (Fig. 1) The controller 28 sets the switching valve 16 as shown in Fig. 1, and the on/off valve Open 27A, 27C to 27F, and open/close valve 27B.
By closing, a heat medium circulation circuit for cooling/dehumidifying mode is formed. As a result, the high-pressure high-temperature heat medium from the compressor 15 passes through the heat exchanger 21 of the outdoor unit 13 by the switching valve 1B, radiates heat to the outside and condenses, and passes through the heat exchanger 23 of the heat storage tank 14 to the heat storage tank. After dissipating heat and condensing into the water of 14,
Indoor air is cooled by passing through the expansion valve 16A and evaporating in the heat exchanger 18 of the indoor unit 12. In this mode, the indoor air is dehumidified by collecting moisture in the indoor air that liquefies in contact with the surface of the heat exchanger 18 into the dehumidifying pan 20.

(Heating mode (Fig. 2)) The control Jl device 28 sets the switching valve 16 as shown in Fig. 2, opens the on-off valves 27A, 27C to 27F, and
By closing 7B, a heating medium circulation circuit is formed. As a result, the high-pressure high-temperature heat medium from the compressor 15 passes through the heat exchanger 1B of the indoor unit 12 by the switching valve 16, radiates heat indoors and condenses, and then passes through the expansion valve 16A for heat exchange in the outdoor unit 13. The water passes through the heat exchanger 23 of the heat storage tank 14 and absorbs the amount of heat from the water in the heat storage tank 14 and evaporates, thereby warming the indoor air.

■Heat storage mode (Fig. 3) The controller 28 sets the switching valve 16 as shown in Fig. 3, opens the on-off valves 27B and 27C127E, and closes the on-off valve 27A.
, 27D, and 27F form a heat medium circulation circuit in heat storage mode.

As a result, the high pressure and high temperature heat medium from the compressor 15 is transferred to the switching valve 1.
6, the heat storage tank 14 passes through the heat exchanger 24 of the heat storage tank 14.
After radiating heat to the water and condensing it, it passes through the expansion valve 16A and the heat exchanger 21 of the outdoor unit 13, absorbs outside air heat, evaporates, and stores the heat in the water in the heat storage tank 14.

Thus, the heat storage device 10 controls the operating state of the thermal cycle in the cooling/dehumidifying mode and the heating mode as described below.

That is, the heat storage device 10 includes an opening/closing detector 29. The open/close detector 29 detects the closed state of an opening such as a window or a doorway of the air-conditioned room in which the outdoor unit 12 is installed. Consists of limit switches, magnetic proximity switches, etc. The detection result of the opening/closing detector 29 is transmitted to the controller 28.

Here, the controller 28 enables the heat storage device 10 to operate in the cooling/dehumidifying mode or the heating mode on the condition that the opening/closing detector 29 detects the closed state of the opening.

Therefore, according to the embodiment described above, the heat storage device 10 is operated on the condition that the opening/closing detector 29 detects the closed state of the opening. That is, the thermal energy that the heat storage device IO exerts on the room is effectively consumed for air conditioning such as cooling, dehumidifying, and heating the room without escaping to the outside space through the open opening.

Note that the controller 28 detects whether the occupant has activated the heat storage device 10 under the condition where the opening/closing detector 29 detects the open state of the opening.
When a driving operation is performed, an alarm sound output circuit may be driven to generate an alarm sound from a speaker.

Furthermore, the present invention is widely applicable not only to the heat pump type air-conditioning/heating heat storage device 10 as in the above embodiment, but also to the operation control of various types of air conditioners such as cooling/dehumidifying devices and heating devices.

Furthermore, in implementing the present invention, if the room to be air-conditioned is equipped with a ventilation port and an open stove or the like is used, which releases exhaust gas into the room to drive the air conditioner,
