It is connected, the temperature sensor is apart from 0.8~1.2m of flooring；The controller real-time reception warming probe and TEMP
The operating states of the units of air source heat pump is adjusted the temperature signal of device, realizes the regulation and control of indoor temperature, including：
Summer air-conditioning working temperature is controlled, and is freezed by the indoor set to indoor, is adopted with warming probe
The temperature of collection sends the controller to as feedback signal；The controller carries out the indoor temperature of feedback and setting value pair
Than, as Δ T >=Δ Ts, wherein, Δ T is the measure difference of Indoor Temperature angle value and set temperature value, and Δ Ts is Indoor Temperature angle value
With the setting difference of set temperature value, controller sends the instruction for improving unit refrigerating capacity to increase the refrigerating capacity of system, so that
Reduce indoor temperature；As Δ T<During Δ Ts, the running status for maintaining unit current；Heat supply in winter working temperature is controlled, and passes through institute
State radiation floor end and carry out heat supply, the temperature gathered using the temperature temperature detector sends the control to as feedback signal
Device；The controller is contrasted the indoor temperature of feedback and setting value, and as Δ T >=Δ Ts, controller sends raising machine
The instruction of group heating capacity is to increase the heating capacity of system, so as to improve indoor temperature；As Δ T<During Δ Ts, maintain unit current
Running status.
Compared with prior art, the beneficial effects of the invention are as follows：
1. using different temperature control systems for different Terminal devices, acquisition parameter more realistically reflects indoor people
The thermal environment situation of member behaviour area, feedback parameter is more accurate, it is ensured that indoor thermal comfort.
2. the temperature control system of matched can reasonably accurately regulate and control running state of air conditioner, realization is supplied on demand,
The high efficiency and energy saving of raising system.
