Detailed description of the invention
In order to save air conditioning energy consumption, the embodiment of the present invention provides a kind of temperature-controlled process, Apparatus and system,Below in conjunction with Figure of description, the preferred embodiments of the present invention are described, should be appreciated that described hereinPreferred embodiment only for description and interpretation the present invention, be not intended to limit the present invention. And do not conflictingSituation under, the feature in embodiment and embodiment in the application can combine mutually.
The embodiment of the present invention provides a kind of temperature-controlled process, as shown in Figure 1, comprises the steps:
Step 101: obtain current indoor return air temperature T1, outside air temperature T2 and air-conditioning air intake temperatureDegree T3;
Step 102: by the magnitude relationship based on air-conditioning EAT T3 and preset temperature T0, and indoorThe magnitude relationship of return air temperature T1 and outside air temperature T2, to entering the indoor return air of outdoor heat exchangerAir-flow size and the adjusting that directly enters the ratio value of the air-flow size of the indoor return air of air-conditioning return air pipeline, controlAir-conditioning EAT T3 after system regulates levels off to preset temperature T0, and wherein, preset temperature T0 is for making skyTune reaches the air-conditioning EAT of design temperature T generation energy consumption minimum;
Wherein, the indoor return air of the process exchange heat that outdoor heat exchanger is discharged enters air-conditioning return air pipeline, withAfter mixing, the indoor return air that directly enters air-conditioning return air pipeline enters air-conditioning.
Said temperature control method is applicable to data center and communications equipment room etc. need to carry out precision control to temperatureThe room of system.
Under normal circumstances, preset temperature T0 is a little less than the design temperature of air-conditioning.
With specific embodiment, method provided by the invention is described in detail below. Fig. 2 is the invention processThe detail flowchart of the temperature-controlled process that example provides, specifically comprises the steps:
Step 201: obtain current indoor return air temperature T1, outside air temperature T2 and air-conditioning air intake temperatureDegree T3.
Specifically can obtain by the temperature sensor in outdoor return air pipeline, in outdoor and air-conditioning intake stack.
Step 202: judge the magnitude relationship of air-conditioning EAT T3 and preset temperature T0, wherein, defaultTemperature T 0 produces the air-conditioning EAT of energy consumption minimum for making air-conditioning reach design temperature T.
In the time that air-conditioning EAT T3 is less than preset temperature T0, enter step 203; When air-conditioning EATWhen T3 is greater than preset temperature T0, enter step 204; When air-conditioning EAT, T3 equals preset temperature T0Time, enter step 205;
Preset temperature T0 can be a temperature value, can be also a temperature range. If preset temperature T0For [T0min,T0max] temperature range, now, air-conditioning EAT T3 is greater than preset temperature T0 and refers to air-conditioningEAT T3 is greater than T0max, air-conditioning EAT T3 is less than preset temperature T0 and refers to air-conditioning EATT3 is less than T0min, air-conditioning EAT T3 equals preset temperature T0 and refers to that air-conditioning EAT T3 is at [T0min,T0max] in scope.
Step 203, judge whether indoor return air temperature T1 is less than outside air temperature T2.
In the time that indoor return air temperature T1 is less than outside air temperature T2, enter step 206; When indoor return airWhen temperature T 1 is not less than outside air temperature T2, enter step 207.

When the indoor return air temperature T1 obtaining is that 25 DEG C, outside air temperature T2 are 30 DEG C, air-conditioning air intake temperatureDegree T3 is 28 DEG C, and when preset temperature T0 is 26 DEG C, now, air-conditioning EAT T3 is greater than preset temperatureT0, indoor return air temperature T1 is not more than outside air temperature T2, enters step 207;
Step 205, the air-flow size that enters the indoor return air of outdoor heat exchanger by controlling controlled air-valve controlAnd the air-flow size that directly enters the indoor return air of air-conditioning return air pipeline, the ratio value that maintains both is constant, dimensionHold air-conditioning EAT T3 and equal preset temperature T0.
Maintain the air-flow size of the indoor return air that enters outdoor heat exchanger and directly enter air-conditioning return air pipelineThe air-flow size of indoor return air constant.
Return to step 201.
Step 206, the air-flow size that enters the indoor return air of outdoor heat exchanger by controlling controlled air-valve controlAnd the air-flow size that directly enters the indoor return air of air-conditioning return air pipeline, regulate both ratio values to become large, controlAir-conditioning EAT T3 after system regulates levels off to preset temperature T0.
Regulate the air-flow of the indoor return air that enters outdoor heat exchanger to become large, directly enter air-conditioning return air pipelineThe air-flow of indoor return air diminishes.
When closing the passage that directly enters air-conditioning return air pipeline, when indoor return air all enters outdoor heat exchanger,Enter the air-flow size and the indoor return air that directly enters air-conditioning return air pipeline of the indoor return air of outdoor heat exchangerThe ratio value maximum of air-flow size.
Return to step 201.
Step 207, the air-flow size that enters the indoor return air of outdoor heat exchanger by controlling controlled wind valve regulationDiminish with the ratio value of air-flow size of the indoor return air that directly enters air-conditioning return air pipeline, after control and regulationAir-conditioning EAT T3 levels off to preset temperature T0.
Regulate the air-flow of indoor return air that enters outdoor heat exchanger to diminish, directly enter air-conditioning return air pipelineIt is large that the air-flow of indoor return air becomes.
When closing the passage that enters outdoor heat exchanger, when indoor return air all directly enters air-conditioning return air pipeline,Enter the air-flow size and the indoor return air that directly enters air-conditioning return air pipeline of the indoor return air of outdoor heat exchangerThe ratio value minimum of air-flow size.
Return to step 201.
The method that adopts the embodiment of the present invention to provide, regulates the air-flow of the indoor return air that enters outdoor heat exchanger largeThe little ratio value with directly entering the air-flow size of the indoor return air of air-conditioning return air pipeline, to regulate air-conditioning air intakeTemperature T 3 levels off to preset temperature T0, reduces the temperature between air-conditioning EAT T3 and preset temperature T0Differ from, and then can reduce the energy consumption of air-conditioning.
