Abstract
The utility model relates to a room heat meter used for detecting the performance of a refrigerator, comprising an indoor side and an outdoor side of a test room which are provided with a reprocessing machine set of the room heat meter, a power meter and a test-bed measurement and control system; the room heat meter is characterized in that: the reprocessing machine set of the room heat meter is provided with a plurality of high, medium and low gear adjustable fans; the top of the test room is provided with an air supply pore plate, and the air outlet of the reprocessing machine set of the room heat meter is arranged in the air supply pore plate; and the position of the air outlet of the reprocessing machine set is provided with a bypass air vent nozzle. The room heat meter can detect refrigerating capacity and heating capacity of an air-conditioner and also can detect the performance of the refrigerator, thus achieving the purpose of saving the investment cost and occupying area.
Description
Technical field
The utility model relates to a kind of pick-up unit, especially relates to a kind of room calorimeter that is used to measure air conditioner, refrigerator performance.
Background technology
The room calorimeter is built according to standard GB/T7725 appendix A, is used to measure refrigerating capacity, the heating capacity of air conditioner.Refrigerating capacity, heat pump heating capacity that the room calorimeter can be measured air conditioner in the indoor and the outside of calorimeter simultaneously.The room calorimeter mainly is made of following several parts: test room, indoor, test room, outside, the air reprocessor group in test room, power meter (being used to measure the electrical quantity of tested air conditioner), testing bench control system, compositions such as chilled water system; To Balanced Ambient Room Type Calorimeter, also have inner room room and inner room temperature control system.In the air reprocessor group in test room, form, it is controlled by testing bench control system by equipment such as heating, humidification, cooling, dehumidifying, ventilations.Calorimeter requires the reprocessor group in test room that the blower fan of enough air quantity all should be installed, and its air quantity is not less than the twice of the air circulation of tested air conditioner indoor or outside respectively.Enough air quantity guarantee that the air-out of reprocessor group and the air-out of tested air conditioner fully mix, and form a stable temperature field and moisture field.
The reprocessor group of general room calorimeter adopts many typhoons machine, and air outlet adopts the outlet grid form, and the air-out of reprocessor group directly is sent in the test room, after the air-out of tested air conditioner mixes, sucks the reprocessor group again; Enough big air quantity guarantees room temperature field stable and uniform, and measuring result error is little.
Build by GB GB/T8059.1-4 refrigerator performance test chamber, and it mainly contains with the lower part and constitutes: the air reprocessor group in test room, test room, power meter (being used to measure the electrical quantity of tested refrigerator), testing bench control system etc.It requires, and flow rate of ambient air should be greater than 0.25m/s in the refrigerator testing laboratory, and in the high scope of separating test platform 2M, the thermograde of its vertical direction should not surpass 2K/M.
More than two testing equipments certain something in common is arranged, as the test room all being arranged, the air reprocessor group, power meter, testing bench control system etc. in test room being arranged; But above two testing equipments require difference too big to the wind speed in test room, generally are to build separately respectively.The testing equipment investment is big like this, and the area of occupied ground is also big.
Summary of the invention
The utility model fundamental purpose is: build a kind of household air-conditioner test that both had been applicable to, can be used for the room calorimeter of refrigerator Performance Detection again.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of room calorimeter that can be used for the refrigerator Performance Detection, comprise testing laboratory indoor and outside, in indoor and outside room calorimeter reprocessor group is housed, power meter, testing bench control system is characterized in that: calorimeter reprocessor group is provided with many high, medium and low shelves adjustable fans; The testing laboratory top is provided with the air-supply orifice plate, and the air outlet of calorimeter reprocessor group is located in the air-supply orifice plate; The place is provided with wind path bypass air port at reprocessor group air outlet.
As preferably, calorimeter reprocessor group is provided with frequency converter, and described frequency converter is connected with fan power.
Therefore, the utility model combines air conditioner, two kinds of different testing equipments that require of refrigerator Performance Detection, can detect refrigerating capacity, the heating capacity of air conditioner, also can detect the refrigerator performance, reach the expense of reducing investment outlay, also save the purpose of floor area.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is room calorimeter reprocessor group synoptic diagram of Fig. 1;
Accompanying drawing 3 is air-supply orifice plate synoptic diagram of Fig. 1.
Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
The room calorimeter that can be used for air conditioner, refrigerator Performance Detection as shown in Figure 1-Figure 3 is equipped with room calorimeter reprocessor group 5, power meter, testing bench control system in testing laboratory indoor 4 and outside 3.The reprocessor group is provided with many high, medium and low shelves adjustable fans, and blower fan is connected with converter power supply, and there are enough air circulations the warranty test chamber.When carrying out the refrigerator Performance Detection, the reprocessor group can only be driven a typhoon machine, operates in low wind shelves, also can open wind path bypass air port B, guarantees that flow rate of ambient air is not more than 0.25m/s in the refrigerator testing laboratory.The testing laboratory top is provided with air-supply orifice plate 6, and the air outlet 2 that makes reprocessor group 5 is by air-supply orifice plate 6, and air-supply guarantees that when the refrigerator performance test in the high scope of separating test platform 2M, the thermograde of its vertical direction is no more than 2K/M vertically downward.The air quantity height range of adjustment of reprocessor group blower fan is reached more than 10 times.When the refrigerating capacity of carrying out air conditioner, heating capacity, many typhoons machine of reprocessor group can be opened high wind shelves, and there are enough air circulations the warranty test chamber; Because of enough air quantity are arranged, can make the test room keep a stable temperature field.
