Description
Technical field:
The utility model relates to a kind of temperature control system of building energy conservation testing instruments, refers more particularly to the buildings exterior-protected structure heat transfer coefficient is carried out the on-the-spot employed recirculating air temperature control system of wall heat transfer coefficient in-situs tester that detects.
Technical background:
Along with the development and the growth in the living standard of society, the human settlements building is consuming the increasing energy.Show according to relevant data: the building energy consumption of developed country accounts for 40% of total energy consumption, and China is about about 25%, occupies various energy consumptions first place, wherein consumes more than 50% on heating in the winter time and the summer refrigeration.Jin Zhang energy supply day by day makes the energy become the key element of restriction economic development.Building trade when improving constantly human settlement's comfort level, reduces the architectural energy consumption total amount as the big power consumer, is effectively to alleviate energy supply and demand contradiction, has an important task of economy, social effect.
Reduce building energy consumption for adapting to country, greatly develop the requirement of energy-saving building, improve the energy-conservation of consumption reduction monitoring ability, a series of regulations and examination criteria have been done to the buildings exterior-protected structure heat transfer coefficient by country, should after the normal operation of heating system, carry out according to the detection to the buildings exterior-protected structure heat transfer coefficient in " heating Residential Buildings Energy test stone ", should be selected in the coldest month and should avoid the weather of temperature acute variation detection time, should not be less than 96 hours detection time, to this, the detection of a lot of buildingss be owing to can not satisfy this regulation and all can't carry out.For not only coincidence detection standard but also can be at any time the heat transfer coefficient of buildings pad structure be detected, Chinese patent CN2828810 discloses a kind of " cold-hot box type heat transfer coefficient detecting instrument ", and this detector comprises hot case, ice chest, control box, refrigeration machine, well heater; This detector advocates that its equipment can solve the scene that all can carry out buildings pad structural thermal performance throughout the year and detect problem; But the inventor discovers: because detection time, requirement was longer, the refrigeration of this detector and pyrogenicity mode can not guarantee the homogeneity of test environment temperature for a long time, cause error information detection big.
Summary of the invention:
Detect the accuracy of data for the scene of improving the wall heat transfer coefficient in-situs tester, the purpose of this utility model provides that a kind of assurance test environment temperature is even, temperature fluctuation range is low, and heat transfer coefficient is detected the small recirculating air temperature control system of data influence.
The technical solution of the utility model implementation is as follows:
A kind of recirculating air temperature control system, it is made up of refrigerating and heating combined equipment, recirculating air device, detection case three parts, the thermopair of being made up of heat flow meter and temperature sensor is installed in the detection case, wherein, the air inlet of detection case is communicated with the air outlet of recirculating air device, the return air inlet of recirculating air device is connected with the air outlet of detection case, and evaporator, heating rod, blower fan are housed in the recirculating air device, and evaporator is connected with refrigerating plant.
In order to carry and on-the-spot easy for installation, detection case is combined by four little detection cases that are interconnected, adorn two pairs of thermopairs in each little detection case, the eight pairs of thermopairs divide in pairs up and down two groups of average marks be listed in four little detection cases into and out of between the air port.
The length and width height of little detection case is 1 meter.
Whole box body adopts inner pressed to seal soft foam and rubber.
Good effect of the present utility model is:
1. guarantee that instrument and equipment all can detect at heating phase, non-heating period;
2. hot and cold control can be regulated according to sense environmental conditions, can select the mode of heating separately or refrigeration to carry out temperature adjusting; Also available heating or refrigeration modes are finely tuned temperature with refrigeration or heating as main temperature regulation mechanism, detect needed steady temperature to reach.
3. the cold and hot recirculating air temperature-controlling system that all adopts, stable temperature control, small to the test result influence.
4, whole box body adopts inner pressed to seal soft foam and rubber, good heat insulating, and hot transmission can be ignored.
Adopt the one-sided erecting equipment of body of wall to make the hot-cool environment temperature when 5, detecting, therefore, detect simple, convenient, fast.
Description of drawings:
Fig. 1 is a detection case theory structure synoptic diagram of the present utility model.
Fig. 2 is a recirculating air principle of device structural representation.
Fig. 3 is a refrigerating plant theory structure synoptic diagram.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1, Fig. 2, Fig. 3 as can be seen: the utility model is made up of refrigerating and heating combined equipment, recirculating air device, detection case three parts, the thermopair of being made up of heat flow meter and temperature sensor 1 is installed in the detection case, wherein, the air inlet 3 of detection case is communicated with the air outlet 5 of recirculating air device, the return air inlet 8 of recirculating air device is communicated with the air outlet 2 of detection case, evaporator 7, heating rod 6, blower fan 4 are housed in the recirculating air device, and evaporator 7 is connected with refrigerating and heating apparatus 9.
Be it can also be seen that by Fig. 1: detection case is combined by four little detection cases that are interconnected, adorn in each little detection case 1, eight pair of thermopair of two pairs of thermopairs 1 divide in pairs up and down two groups of average marks be listed in four little detection cases into and out of between the air port.The optimum dimension length and width height of little detection case is 1 meter.
Whole box body is made with soft foam of inner pressed and rubber, good heat insulating, and hot transmission can be ignored.
During execute-in-place, dress detection case opening part is buckled in body of wall one side and fixes, and dividing eight pairs of thermopairs up and down in pairs, two groups of average marks are listed in casing into and out of between the air port, time recording measuring point temperature, according to the indoor and outdoor surroundings condition, select refrigeration or heat, connect the casing air inlet by the fan outlet of recirculating air device, the air outlet of casing connects the return air inlet of recirculating air device, after The whole control system installs, choose the temperature that need reach on controller, press power switch, system starts working.
Air after the recirculating air device will be risen or lower the temperature is sent in the case by the casing air inlet, and parallel-flow is crossed box house and flowed out by air outlet, enters the recirculating air device via return air inlet and finishes next step circulation, finishes up to whole test job.
