Such as：The Chinese invention patent of Publication No. CN106869673A, disclose it is a kind of based on environmental monitoring system from The application method of dynamic switch door and window is the sensor mechanism of environmental monitoring to be used in outdoor increase, for monitoring using step The wind-force size of ambient enviroment；Sensor mechanism is connected with signal conversion module again, carries out signal conversion, obtains analog signal. The Chinese invention patent of Publication No. CN103528167A discloses a kind of efficiency for taking into account air conditioner energy saving and ambient air quality The method and system of monitoring, the method is characterized in that including the following steps：Step S01：It monitors in real time and shows in office Microenvironment situation, including outdoor temperature, outside humidity, room temperature, outside humidity, interior CO2Solubility and air-conditioning work State, opening and closing windows state.Above-mentioned two patents respectively give single switch window and switch the application method of air-conditioning, still In combination cooling operation building, window and switch air-conditioning are existed simultaneously, and above two patents do not provide window and open Close the control method that air-conditioning is adjusted simultaneously.
Summary of the invention
In conclusion in order to overcome the deficiencies of the prior art, technical problem to be solved by the invention is to provide a kind of interiors The optimal control method of combination cooling.
The technical solution that the present invention solves above-mentioned technical problem is as follows：A kind of optimal control method of interior combination cooling, It includes the following steps, namely：
Step S1 is consulted《Civil buildings heating ventilator is related to standardizing with air conditioning》GB50736-2012 is obtained differently Area difference occasion heat supply setting value TheWith cooling set point TAC；
Step S3, by comparing The、TAC、Tout、THL、TLLAnd room temperature TinControl the switch of air-conditioning and window, Control method is as follows：
(1) work as TLL≤Tin≤THL&Tin>The&The>At 16 DEG C, closes air-conditioning and windowing or pass air-conditioning close window；
(2) work as Tin<TLLWhen, turn on the aircondition heat supply and pass window or pass air-conditioning and pass window；
(3) work as THL<TinWhen, cooling supply of turning on the aircondition and close window or close air-conditioning and close window.
The beneficial effects of the invention are as follows：It is improved using this method annual fractional energy savings to 31%, which can be same When control window and air-conditioning on or off, by the optimization built for combination cooling run technology and theory support are provided, also for The intelligent control device of research and development combination cooling building lays the foundation.
Based on the above technical solution, the present invention can also do improvement further below：
Further, T is passed through according to following formula in step S2outCalculate the acceptable indoor temperature range of 80% crowd Upper limit THLWith lower limit TLL：
THL=Tout×0.31+21.3；TLL=Tout×0.31+14.3。
Beneficial effect using above-mentioned further scheme is：Obtain the upper limit of the acceptable indoor temperature range of 80% crowd THLWith lower limit TLL。
Further, as TLL≤Tin≤THL&Tin in step S3>The&The>At 16 DEG C, if indoor someone's activity Close air-conditioning and windowing.
Further, as TLL≤Tin≤THL&Tin in step S3>The&The>At 16 DEG C, if indoor unmanned activity It closes air-conditioning and closes window.
Further, work as T in step S3in<TLLAnd TLL<TheWhen, turn on the aircondition if indoor someone's activity heat supply and pass window.
Further, work as T in step S3in<TLLAnd TLL≥TheWhen, it closes air-conditioning and closes window.
Further, work as T in step S3HL<TinAnd THL>TACWhen, cooling supply of turning on the aircondition if indoor someone's activity and close window.
Further, work as T in step S3HL<TinAnd THL≤TACWhen, it closes air-conditioning and closes window.
Detailed description of the invention
Fig. 1 is control flow chart of the invention.
Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and It is non-to be used to limit the scope of the invention.
As shown in Figure 1, a kind of optimal control method of interior combination cooling, includes the following steps, namely：
Step S1 is consulted《Civil buildings heating ventilator is related to standardizing with air conditioning》GB50736-2012 is obtained differently Area difference occasion heat supply setting value TheWith cooling set point TAC；
Step S2 consults local meteorological data and obtains local outdoor monthly mean temperature Tout, passed through according to following formula ToutCalculate the upper limit T of the acceptable indoor temperature range of 80% crowdHLWith lower limit TLL：
THL=Tout×0.31+21.3；TLL=Tout×0.31+14.3；
Step S3, by comparing The、TAC、Tout、THL、TLLAnd room temperature TinControl the switch of air-conditioning and window, Control method is as follows：
(1) work as TLL≤Tin≤THL&Tin>The&The>When 16 DEG C (catching cold lower than the temperature value human body easy to catch cold), if Air-conditioning and windowing are just closed in indoor someone's activity, reduce indoor air temperature using outdoor natural wind；If indoor unmanned activity It closes air-conditioning and closes window (it is antitheft for closing window)；
(2) work as Tin<TLLWhen：
1. working as Tin<TLLAnd TLL<TheWhen, turn on the aircondition if indoor someone's activity heat supply and pass window；
2. working as Tin<TLLAnd TLL≥TheWhen, it closes air-conditioning and closes window, other modes can be used such as warm oneself by a fire and improve Interior Space temperature Degree；
