Problems solved by technology

[0002] Hotel rooms are often vacant, but in order to ensure that the staff can enjoy a comfortable temperature environment immediately after check-in, in order to improve the management level of the hotel, the room temperature is also set near the comfortable temperature when the room is vacant, which undoubtedly increases Useless air conditioning energy consumption
In order to save energy consumption of air conditioners, some thermostats are designed with an empty room working mode to control the room temperature according to the usage of the room. ) to achieve the purpose of energy saving, that is, the thermostat enters the vacant room mode after the personnel leave the room. Restore the original comfortable temperature setting value, but this control product only provides users with a summer room temperature setting range (for example, 28~31°C), and it is difficult for users to adjust according to the local climate conditions and thermal engineering of the building in practical applications. Features, etc. to pre-scientifically set the room temperature value in the vacant room mode, and the management personnel cannot reasonably set the room temperature according to the use requirements and load conditions, and it is easy to lag behind, which limits the use of its energy-saving features
However, the current adaptive room temperature predictive controller based on predictive control technology (such as a thermostat based on BP neural network predictive model) is not only expensive but also requires a large amount of historical data for training, so it is difficult to promote in practical applications.
Some technical products establish the function of the indoor temperature setting value changing with the outdoor climate, and automatically reset the room temperature setting value by monitoring the outdoor temperature and humidity, solar radiation intensity and other weather conditions, but this method needs to install expensive sensors outdoors , and even need climate stations and the monitoring of weather conditions is not accurate, so it is difficult to promote in practical applications

Embodiment Construction

[0045] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

[0046] Such as figure 1 As shown, the room temperature control method of the present invention includes the control method in the vacant room mode after the personnel leave the system and starts, and the implementation steps of the temperature control method in the vacant room mode are as follows:

[0047] Step 1: After the thermostat receives the signal of people leaving, load the vacant room driver. The leaving signal includes the signal sent by door card linkage, manual switching, etc.;

[0048] Step 2: Collect user input data, including room size, comfortable temperature setting value, heat transfer coefficient, full-power cooling capacity of air conditioner and t...

Abstract

The invention discloses a room temperature control method which mainly comprises a control method under an empty room pattern, and also comprises a control mode under a guest greeting pattern. Comfort temperature acquisition in set time is taken as a control target after people live again, the comfort degree and satisfaction degree of people can be considered when people just live, and the energy-saving requirement of an air conditioning system by scientific control of room temperature under the empty room pattern can be met. According to the invention, a sensor is not required to be installed outdoors, the heat gaining condition of air in a room can be monitored and the time of predicting room temperature to comfortable temperature after starting up can be forecast by only collecting air temperature and average radiation temperature under the empty room pattern; and the method is especially suitable for room temperature control of guest rooms of star-level hotels under the empty room pattern, and also can be applied to air conditioner forecasting control of other living buildings when in startup and shutdown in advance.

Description

technical field [0001] The invention relates to a room temperature control method, in particular to a room temperature control method which can ensure that the personnel can check in again after leaving the room for a long time, and obtain a comfortable temperature within a set time. Background technique [0002] Hotel rooms are often vacant, but in most star-rated hotels, in order to ensure that personnel can enjoy a comfortable temperature environment immediately after check-in, in order to improve the management level of the hotel, the room temperature is also set near the comfortable temperature when the room is vacant, which undoubtedly increases Useless air conditioning energy consumption. In order to save energy consumption of air conditioners, some thermostats are designed with an empty room working mode to control the room temperature according to the usage of the room. ) to achieve the purpose of energy saving, that is, after the personnel leave the room, the ther...
