Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mixes an electric air conditioner and a gas air conditioner in the same air-conditioned section, and centralizes control of each of these air conditioners by the same controller. The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art Generally, a conventional air conditioner has a plurality of electric air conditioners installed in an air-conditioned compartment, and each air conditioner is controlled by a single controller to perform air conditioning. Figure 4 shows, for example, "Frozen Vol. 67 No. 776" (6th 1992).
It is a figure which shows the structure of the conventional air conditioner of this kind described by the moon Japan Frozen Association). In the figure, reference numeral 1 denotes a building as an air-conditioned section, which is composed of rooms 1a to 1e. 2 to 4 are outdoor units provided adjacent to the roof and side walls of the building 1, and 5 are controllers 2a to 2c which are arranged in the room 1a and are connected to the outdoor units 2 to 4 by wiring 6. Is an indoor unit 3a disposed in each of the rooms 1b to 1d and connected to the outdoor unit 2 by a pipe / wiring 7.
To 3c are indoor units 4b and 4b, which are arranged in each of the chambers 1b to 1d and are connected to the outdoor unit 3 by piping / wiring 8.
It is an indoor unit that is disposed inside and is connected to the outdoor unit 4 by piping / wiring 9.

In the conventional air conditioner configured as described above, the outdoor unit 2 and the indoor units 2a to 2c, the outdoor unit 3 and the indoor units 3 which are connected by the pipes and wirings 7 to 9 respectively.
a to 3c, the outdoor unit 4, and the indoor units 4a and 4b respectively constitute an electric air conditioner, and the controller 5 controls the outdoor units 2 to 2 respectively.
By controlling 4, the indoor units 2a to 2c, 3a to
Chambers 1b to 1e in which 3c, 4a and 4b are respectively arranged
Air conditioning is performed by cooling or heating the inside to a desired temperature.

[0004]

Since the conventional air conditioner is constructed as described above, the amount of electric power used is equal to that of the building 1.
If the contracted electric energy is exceeded, it is necessary to stop one of the air conditioners to reduce the electric energy used. However,
Since the case where the amount of power used exceeds the contracted amount of power is generally during the summer when the air conditioning load is large, stopping the air conditioner not only raises the temperature in each room 1a-1e, but also impairs comfort, and the computer However, there is a problem that the equipment is affected when such equipment is installed. Also, since the electric air conditioner covers all the air conditioning, for example, the power consumption is 50
If the voltage exceeds kVA, a high-voltage power receiving facility must be installed, which is a big economical problem.

The present invention has been made in order to solve the above problems, and an object thereof is to provide an air conditioner which is excellent in economy without impairing comfort.

[0006]

In the air conditioner according to the first aspect of the present invention, a gas type air conditioner and an electric type air conditioner are mixedly arranged in the same air-conditioned section, and each air conditioner is arranged. The machine is centrally controlled by the same controller.

Further, the air conditioner according to the second aspect of the present invention is such that the electric air conditioner is stopped when the power consumption of the air-conditioned compartment exceeds the contracted power consumption.

In the air conditioner according to the third aspect of the present invention, the electric air conditioner is preferentially operated during the midnight time when the electricity charge is low.

The air conditioner according to claim 4 of the present invention uses a heat storage refrigerator as an electric air conditioner,
This heat storage refrigerator is operated to store heat during the late night hours when the electricity charges are low, and the heat generated by the heat storage refrigerator is used as the heat source during the hours other than midnight, and gas-type air conditioning is used. It was designed to operate the machine.

[0010]

The electric air conditioner of the air conditioner according to the present invention is stopped when the power consumption of the air-conditioned section exceeds the contract power consumption, and is preferentially operated during the midnight hours.
Further, the gas type air conditioner is preferentially operated when the power consumption of the air-conditioned compartment exceeds the contract power consumption. Further, the heat storage refrigerating machine operates and stores heat in the midnight time zone, and supplies this heat as a heat source of the gas type air conditioner operated in the non-midnight time zone.
