AI Technical Summary

Problems solved by technology

First, compared to other sensors such as temperature sensors, the price of flow sensors is very high
The second, the setting of flow sensor is very troublesome (especially under the situation that is arranged in existing air-conditioning equipment, must make air-conditioning equipment stop
Third, the measurement error caused by the wrong setting of the flow sensor is very large
Fourth, regarding flow sensors, regular maintenance is required to maintain measurement accuracy
[0007] Therefore, even if the above-mentioned conventional technology is used to save energy, good cost-effectiveness may not be obtained.
In addition, for existing air conditioners, the above-mentioned conventional technologies may not be practically applied.

Embodiment approach 1

[0071] when based on Figure 1 to Figure 6 One embodiment (Embodiment 1) of the present invention will be described as follows.

[0072] (Outline of equipment control system)

[0073] First, based on figure 2 The outline of the device control system of this embodiment will be described. figure 2 It is a block diagram showing an example of the structure of the equipment control system 9 of Embodiment 1.

[0074] Such as figure 2 As shown, the equipment control system 9 includes: a control device (heat demand estimation device, equipment control device) 1 , a control relay 2 , an air conditioner 4 , and a refrigerator power sensor 5 .

[0075] (control device)

[0076] The control device 1 estimates the heat demand of the air conditioner 4 based on the data acquired from the refrigerator power sensor 5 , and controls the air conditioner 4 based on the estimated heat demand. Specifically, the control device 1 transmits a control signal to each device of the air condition...

Embodiment approach 2

[0132] when based on Figure 7 ~ Figure 11 Another embodiment (Embodiment 2) of the present invention will be described as follows. In addition, for convenience of explanation, components having the same functions as those shown in Embodiment 1 above are denoted by the same reference numerals and their descriptions are omitted.

[0133] In the second embodiment, by learning and deriving the above-mentioned conversion function 31 , the estimation error of the estimated heat demand is reduced compared with the first embodiment. Hereinafter, in Embodiment 2, differences from Embodiment 1 will be mainly described.

[0134] (Outline of equipment control system)

[0135] First, based on Figure 7 The outline of the device control system of this embodiment will be described. Figure 7 It is a block diagram showing an example of the structure of the equipment control system 9a of Embodiment 2.

[0136] Such as Figure 7 As shown, compared with the equipment control system 9 , th...

Embodiment approach 3

[0174] when based on Figure 12 to Figure 14 Another embodiment (Embodiment 3) of the present invention will be described as follows. In addition, for convenience of explanation, components having the same functions as those shown in Embodiment 1 and Embodiment 2 above are given the same reference numerals and their descriptions are omitted.

[0175] In Embodiment 2, since no flow sensor is provided to estimate the cold water flow rate, it is necessary to fix the cold water flow rate (set flow rate of the cold water pump 44). However, in order to maintain the comfort of the living room or maintain the equipment, the air conditioner 4 may change the operation content of the air conditioner through the judgment of the on-site operator or the control of the existing system. Therefore, the set flow rate of the cold water pump 44 may not be fixed, and the learning process may not be performed.

[0176] Therefore, in the present embodiment, even if the cold water flow rate fluctua...

Abstract

A heat demand estimation device and method and a facility control device, method and system are provided (a heat demand estimation device, a heat demand estimation method, a facility control device, a facility control method, a facility control system, a control program, and a recording medium). The heat demand estimation device estimates heat demand of an air conditioning facility without installing a flow sensor. The heat demand estimation device includes: a data collection part (21) which obtains refrigeration machine electric power data from a refrigeration machine electric power sensor (5) which measures electrical power consumption of a refrigeration machine (43) of an air conditioning facility (4); and an estimated heat demand amount calculation part (22) which calculates an estimated heat demand amount from the electrical power consumption of the refrigeration machine (43) that is indicated by the refrigeration machine electric power data to output the estimated heat demand amount.

Description

technical field [0001] The present invention relates to a heat demand estimating device and a heat demand estimating method for estimating the heat demand of an air conditioner, an equipment control device for controlling an air conditioner based on the heat demand estimated by the heat demand estimation device, an equipment control method, an equipment control system, a control program, and a record medium. Background technique [0002] In recent years, from the standpoint of global warming prevention, cost reduction, and request for revision of the Energy Conservation Law, energy conservation of various equipment (especially air-conditioning equipment) installed in offices, factories, houses, etc. has been progressing. Here, there are roughly two methods of energy saving. As this method, the first method is to control the operation of various devices so that the minimum necessary energy is supplied, and the second method is to control the operation of various devices so t...
