The selective control switching device shifter 11 of ventilating system of the present invention opens or cuts out, and is namely optionally communicated with by opening or close switching device shifter 11 or disconnects chamber 6 and air outlet 3, thus controls underground pipe 1 air feed situation.Especially, in FIG to represent that with the dotted line of arrow transducing signal is sent to control device 9 by the second temperature humidity parts 22, remaining part and the Signal transmissions between sensor with control device 9 identical with it, no longer illustrate.Specifically, the air outlet 3 of underground pipe 1 is for exporting the air through underground pipe heating or cooling, and preferably as shown in fig. 1, air outlet 3 protrudes from soil to be easy for installation and removal.Preferably, this ventilating system is communicated with air outlet 2 and chamber 6 by pipeline 10, and switching device shifter 11 is Electric air valve, makes to be communicated with between chamber 6 and air outlet 3 or to disconnect by the opening and closing of Electric air valve.First temperature humidity parts 4 send temperature signal and moisture signal to control device 9, control device 9 receives this temperature signal and moisture signal to obtain the temperature and humidity in underground pipe air outlet 3, namely can obtain the temperature and humidity through the cooled air of underground pipe, that is can obtain the temperature and humidity for the air carried in chamber.According to said temperature and humidity, control system 9 can judge whether underground pipe air-supply meets air-conditioning requirement in chamber 6 and send the first switch order, switching device shifter 11 responds the first switch order and opens or cut out, namely control system 9 sends open command, switching device shifter 11 is opened and chamber 6 is communicated with air outlet 3, and underground pipe 1 can be blown for chamber 6; Control system 9 sends out code, switching device shifter 11 close make chamber 6 and air outlet 3 be communicated with disconnection, underground pipe 1 can not be blown for chamber 6.In one embodiment of the invention, chamber 6 is the chamber in building.
With reference to Fig. 3, when needing to lower the temperature to chamber 6, the method adopting above-mentioned ventilating system to control temperature in chamber comprises the following steps:
Step 1: the wind pushing temperature value t2 that the first temperature humidity parts 4 record and blasting humidity value d2 passes to control device 9, control device 9 calculates air-supply enthalpy i2;
Step 2: air-supply enthalpy i2 and default enthalpy i1 compares by control device 9, when the enthalpy i2 that blows is less than or equal to default enthalpy i1, control device 9 instruction switching device shifter 11 is opened, and communicates to make underground pipe 1 and chamber 6.
That is, first the wind pushing temperature value t2 that records according to the first temperature humidity parts 4 of control device 9 and blasting humidity value d2 calculates air-supply enthalpy i2.Then, judge, if air-supply enthalpy i2 is less than or equal to default enthalpy i1, control device 9 controls switching device shifter 11 and opens thus air outlet 3 is communicated with chamber 6, if air-supply enthalpy i2 is less than default enthalpy i1, control device 9 controls switching device shifter 11 and cuts out thus air outlet 3 was disconnected with being communicated with of chamber 6.Above based on the temperature detection signal of the first temperature humidity parts 4 and the enthalpy of Humidity Detection signal acquisition, and the enthalpy carried out subsequently compares and obtains the first switch order, in fact just can be expressed as: control device 9 receives the transducing signal of the first temperature humidity parts 4 and exports the first switch order.Specifically, enthalpy calculates by enthalpy computing formula, and this computing formula is:
I=1.01t+ (2500+1.84t) d or i=(1.0l+1.84d) t+2500d (kJ/ (kg dry air))
In formula: t--air themperature (DEG C);
The water capacity (g/ (kg dry air)) of d--air;
The average specific heat at constant pressure (kJ/ (kgK)) of 1.01--dry air;
The average specific heat at constant pressure (kJ/ (kgK)) of 1.84--steam;
