Please refer to the first diagram to the third diagram, wherein the first diagram is a system block diagram showing an energy-saving control system provided by an embodiment of the present invention; the second diagram is an energy-saving control system provided by an embodiment of the present invention The operation diagram of the processing module; and the third diagram shows the operation display of the input module of the energy-saving control system provided by an embodiment of the present invention Show interface diagram. As shown in the figure, an energy-saving control system 1 according to an embodiment of the present invention is used to control a temperature control device 2 and includes an input module 11, a receiving module 12, a sensing module 13, and a processing module. 14 与 一个 控制 模型 15。 14 and a control module 15. Wherein, the temperature control device 2 is set in an operation space and has a target temperature set in the operation space. In this embodiment, the temperature control device 2 is an air conditioner and the operation space temperature control device 2 is in a space such as : Room, office, etc. with a space temperature.

In addition, the periphery of the operating space is defined as an external environment and has an external temperature. It is illustrated with a more understandable but exaggerated example. For example, if the operating space is a single-family villa in the mountain, the external environment is the surrounding area Mountain forest environment.

The input module 11 is used to input a plurality of spatial parameters corresponding to the operating space, such as: air heat capacity, total space heat, and target temperature. In this embodiment, the external temperature is also input. The receiving module 12 is electrically connected to the input module 11 for receiving spatial parameters. The sensing module 13 is used to sense the space temperature of the operating space.

The processing module 14 is electrically connected to the receiving module 12 and the sensing module 13 and receives a space parameter and a space temperature for calculating a heat transfer amount. The control module 15 is electrically connected to the processing module 14 and receives a heat transfer amount and generates a control signal accordingly to control the temperature control device 2.

As shown in the second figure, it is a calculation diagram of the processing module 14. Among them, Trm is the space temperature of the operating space; Qg is the sum of the heat generated by all the items and people in the operating space, which is called the total space heat. For the sake of one embodiment, it can be assumed that the space is always hot. The quantity Qg is a fixed value; Qor is the heat that the external environment enters the operating space through various heat transfer methods, which is called external heat flow; Cr is the air heat capacity in the operating space, and its value is the air mass of the operating space times the specific heat of the air Text is the external temperature of the external environment; Rw is the thermal resistance of the medium that isolates the operating space from the external environment. In this embodiment, the medium is a wall. The difference between the external temperature Text and the space temperature Trm divided by the medium thermal resistance Rw is the external heat flux Qor; Qair is the amount of heat transferred by the temperature control device 2 and can be adjusted by adjusting the temperature control device 2 The amount of rotation Qair, and the amount of heat transfer Qair is related to the difference between the space temperature Trm and the target temperature; 1 / S is the integral, which is common knowledge in the technical field to which it belongs, so it will not be repeated.

The diagram is easily understood by those with ordinary knowledge in the technical field, and is expressed as ΔTrm = (Qg + Qor-Qair) / Cr. The processing module 14 receives the space temperature Trm, the air heat capacity Cr, the total space heat Qg, the external temperature Text and the medium thermal resistance Rw to calculate the heat transfer amount Qair. The heat transfer amount Qair is related to the difference between the target temperature and the space temperature Trm. As the difference between the space temperature Trm and the target temperature becomes smaller and smaller, the heat transfer amount Qair also becomes smaller. The control module 15 generates a corresponding control signal according to the heat transfer amount Qair calculated by the processing module 14 to control the temperature control device 2. If the heat transfer amount Qair is smaller, the speed of the temperature control device 2 is reduced.

In addition, a "setting" function can be used by a user to set the temperature control device 2, such as setting a target temperature, wind speed, wind direction, and the like. This figure shows two temperature control devices 2 (named 401 and 402). In addition, the "schedule" function allows a user to schedule the temperature control device 2, for example, to set the time at which the temperature control device 2 starts to operate, and how long it continues to operate, or to set the time for the temperature control device 2 The electricity price mode operates at the off-peak hours when the unit price of electricity is cheaper, in order to save energy and reduce electricity expenses.
