, and the good experience of user is ensure that, and indoor air comfort is improve, operation is simple for the temperature setting method.
As shown in figure 1, the schematic flow sheet of the temperature setting method let cool in cold emission air conditioning system cold-storage of the invention
In, the method is comprised the following steps：
Step S1, collection adopt the observed temperature Ts of the indoor wall surface of phase-changing energy storage material.
Specifically, in inventive embodiment, the interior of the indoor cooling for needed for cold emission air conditioning system, i.e. cold emission are empty
The coverage of adjusting system.The body of wall of interior referred herein is the body of wall for employing phase-changing energy storage material, that is, be mixed into energy storage
The body of wall formed by the construction material of material composition.In actual applications, if temperature properly, can be mixed in construction material
Various energy storage materials.Usually, for the ease of the indoor temperature of control or humidity etc., phase-changing energy storage material is preferably one kind.Enter
One step ground, such as a kind of one fixed phase transition temperature of phase-changing energy storage material correspondence, solidification temperature, fusion temperature.
Preferably, in this step, the observed temperature Ts of the indoor wall surface of phase-changing energy storage material can be passed by temperature
Sensor is measured in real time to indoor wall surface temperature, to obtain its real-time temperature.Further, in order that measuring in real time
Surface of wall temperature it is more accurate, multiple temperature sensors can be set indoors, it is preferable that can indoors four metopes it is each respectively
The surface of wall temperature for arranging a temperature sensor to detect.It is to be appreciated that in an embodiment of the present invention, indoor wall
The meansigma methodss of the surface of wall temperature that the observed temperature Ts on surface is detected by each temperature sensor.For example, indoors four
Metope difference each setting one temperature sensor A1, A2, A3 and A4, the respectively Ts1 of the surface of wall temperature measured by which,
Ts2, Ts3, Ts4, then Ts=(Ts1+Ts2+Ts3+Ts4)/4.
In addition, the observed temperature Ts of indoor wall surface can be cold emission air conditioning system in running every 15 to
The indoor wall surface temperature for being detected by temperature sensor once for 30 minutes, which is the actual measurement of a certain moment indoor wall surface
Temperature.In the example of the present invention, in order to detect in time while can reach stability contorting cold emission air conditioning system
The change of system, preferably measured an indoor wall surface temperature every 15 minutes.

For 0；When the observed temperature Ts of indoor wall surface is higher than the solidification temperature Tf of phase-changing energy storage material and is less than phase-changing energy storage material
Fusion temperature Tm when, the surface of wall output state value of cold emission air conditioning system is 0.5；When the actual measurement temperature of indoor wall surface
When degree Ts is higher than fusion temperature Tm of phase-change material, the surface of wall output state value of cold emission air conditioning system is 1.
Step S3, according to peak value electricity price time tday, valley electricity price time tnight, work hours toffice, and it is next when
Between tnon-office, judge the time period residing for indoor daily schedule t, and the cold emission air-conditioning system obtained by following formula
System ceiling face output state value Ceilingstatus；
Wherein,
tnon-office：Represent the quitting time；
toffice：Represent the work hours.
Surface of wall output state value Wall of cold emission air conditioning system is obtained in step S2statusAfterwards, further, root
According to indoor daily schedule t, its overlapping cases with time-of-use tariffs is judged.
Specifically, the indoor coverage for being cold emission air conditioning system, daily schedule are cold emission air conditioning system
The commuter time of coverage.In other words, the personnel in region for needing cold-storage and letting cool equivalent to cold emission air conditioning system
Situation, work hours have represented personnel's situation in coverage；Quitting time represents and does not have personnel in coverage.
Time-of-use tariffs are peak value electricity price and valley electricity price, and peak value electricity price represents power price height, and it is low that valley electricity price represents power price.
In the example of the present invention, it is according to the daily schedule t (i.e. commuter time) in peak value electricity price time room and peak value electricity price
Time tday, valley electricity price time tnightOverlapping region situation to cold emission air conditioning system ceiling face output state value
Judged, obtained cold emission air conditioning system ceiling face output state value Ceilingstatus.By cold emission air conditioning system day
Card surface output state value CeilingstatusWith indoor daily schedule t and peak value electricity price time tday, the valley electricity price time
tnightLogical calculated formula (as illustrated as the former), can obtain, when indoor daily schedule t is in peak value electricity price and be the non-work hours
Time period when, cold emission air conditioning system ceiling face output state value CeilingstatusCold emission is closed for 0, i.e. expression
Air conditioning system；When indoor daily schedule t is in peak value electricity price and when being the time period of work hours, cold emission air conditioning system variola
Plate surface output state value CeilingstatusIt is to represent opening cold emission air conditioning system for 0.25,0.75,1.
Step S4, according to surface of wall output state value WallstatusWith ceiling face output state value
Ceilingstatus, setting value Tr of cold emission air conditioning system ceiling face temperature is obtained, to control cold emission air conditioning system
Operation.
Specifically, at a time (be assumed to be the To moment) by by indoor wall surface the To moment observed temperature
The solidification temperature Tf of the phase-change material adopted by Ts and the body of wall, fusion temperature Tm are compared the output for obtaining surface of wall
State value Wallstatus, in combination with ceiling face output state value Ceilingstatus, cold emission air conditioning system day can be obtained
Setting value Tr of card surface temperature, and then the operation according to setting value Tr to cold emission air conditioning system regulates and controls, that is, control
The unlatching or stopping of refrigeration air-conditioning system, or by setting that cold emission air conditioning system ceiling face temperature is set to be obtained
Definite value Tr.
