Description
Technical field:
The utility model relates to a kind of temperature control backup system of building energy conservation testing instruments, relates in particular to the water cycle refrigeration system in the employed recirculating air temperature control system of wall heat transfer coefficient in-situs tester that the buildings exterior-protected structure heat transfer coefficient is carried out detecting at the scene.
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, there are certain regulation and examination criteria in country to the buildings exterior-protected structure heat transfer coefficient, 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, therefore, the detection of a lot of buildingss all can't detect owing to can not satisfy this regulation.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 is advocated to solve the scene that all can carry out buildings pad structural thermal performance throughout the year and is detected problem; But the inventor discovers: because detection time, requirement was longer, the refrigeration of this detector and the mode of heating can not guarantee the homogeneity of test environment temperature for a long time, cause error information detection big.The inventor once adopted needs the air of refrigeration directly to pass from A/C evaporator, obtained comparatively ideal effect, but the inventor further tests discovery, when environment temperature needs cryogenic refrigeration, when the air temperature difference of evaporator two sides is big, water vapour contained in its air will be very fast in the evaporator surface frosting, work long hours to cause the evaporator surface freeze over, need the air of refrigeration to pass through, the air channel blocks, and refrigeration work can't continue.
Summary of the invention:
Detect the accuracy of data for the scene of improving the wall heat transfer coefficient in-situs tester, guarantee that its recirculating air temperature control system is better controlled the environment measuring temperature, the purpose of this utility model provide a kind of test environment temperature evenly, heat transfer coefficient detects the water cycle refrigeration system that error is little, the testing environment temperature range is big.
The technical solution of the utility model implementation is as follows:
A kind of water cycle refrigeration system, form by refrigerating plant, recirculating air device, detection case, water tank four parts, the thermopair of being made up of heat flow meter and temperature sensor is installed in the detection case, it is characterized in that: the air inlet of detection case is communicated with the air outlet of recirculating air device, air outlet is communicated with recirculating air device return air inlet, in the recirculating air device air chamber evaporator, blower fan are housed, evaporator is communicated with water tank by water pump, water tank is connected with refrigerating plant, and water tank, water pump, evaporator constitute a water cycle.
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. heating phase, non-heating period all can detect;
2. can regulate according to sense environmental conditions.
3. refrigeration adopts and to carry out the water refrigeration earlier, then to the temperature-controlling system of recirculating air refrigeration, and stable temperature control, test error is little, and can not make the phenomenon that the influence of evaporator surface freeze over detects.
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 structural representation of the present utility model.
Fig. 2 is a cold water loop structure synoptic diagram.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1, Fig. 2 as can be seen: the utility model is made up of refrigerating plant, recirculating air device, detection case, water tank four parts, the thermopair of being made up of heat flow meter and temperature sensor 1 is installed in the detection case, the air inlet 3 of detection case is communicated with the air outlet 5 of recirculating air device, air outlet 2 is communicated with recirculating air device return air inlet 7, evaporator 6, blower fan 4 are housed in the recirculating air device air chamber, evaporator is communicated with water tank 9 by water pump 8, water tank 9 is connected with refrigerating plant 10, and water tank 9, water pump 8, evaporator 6 constitute a water cycle.
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 two pairs of 1, eight pair of thermopairs of thermopair of forming by heat flow meter and temperature sensor 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 high optimum dimension of the length and width of little detection case is 1 meter.
