Air conditioner air-out measurement mechanism with spiral mixing and pipe sampling mechanism
Technical field
The utility model relates to the measurement mechanism of air conditioner leaving air temp and air quantity.
Background technology
Temperature and air-flow measurement device are the measuring equipments that is used for air conditioner leaving air temp and its air quantity, mainly by airtight air compartment with wherein temperature mixing arrangement, temperature sampler and nozzle, nozzle installing plate and induced draft fan are formed.
Typical mixing arrangement and sampling apparatus are generally formed circle or rectangle mixer by two groups of window shutters, and the blinds of this mixer can make the air that flows through mixer produce the compound action of shearing and relative displacement in adjacent two districts.
Using mixing arrangement is very suitable on principle, and it can satisfy the restriction of the desired unevenness of operating condition of test of regulation.When the cross direction profiles measurement of temperature and speed shows that unevenness is the thermal equilibrium failure reasons, just should use mixer.The good mixing device is huge, and its size must be determined by required air capacity.Guarantee the homogeneity in temperature field by suitable mixing arrangement.
If temperature is uniformly really, can measure medial temperature with sampler.And space that needs and power of fan are littler than the mixer that is arranged in primary air.Can use a little blower fan to introduce air, make it to flow through temperature measuring device.This blower fan must be positioned at the downstream of temperature measurer, to prevent the heat effects temperature number of degrees that number goes out blower fan.When the sampling air is obtained in certain between the measurement mechanism of just tested equipment and air mass flow, must be that the sampling air turns back in the primary air, to avoid moving away the air capacity an of the unknown from the air-flow measurement device.
According to the mixer of above-mentioned requirements design, its sectional dimension is consistent with corresponding apparatus for measuring air quantity, and size is very big; When big air mass flow, can guarantee the homogeneity in temperature field substantially, cross section each point temperature all guarantees at ± 0.5 ℃; The accuracy and the reliability of measuring system joined and can be guaranteed when using to it and supporting sampler.Yet when little air mass flow, the bulky size of mixer makes that the each point temperature by its cross section can't be identical, cross section each point temperature-difference can reach ± and 7 ℃.We can't illustrate that also the each point temperature is a homogeneity after using supporting sampler; The actual temperature that more can't reflect air really; Do not reach its intended purposes; Simultaneously because size is huge, moving air closure casing hot or loss of heat also can be introduced error, the regenerative effect of its structured material also can be postponed the acquisition steady working condition in addition.
Summary of the invention
In order to reduce measuring error, the homogeneity of the temperature spot in temperature survey cross section when guaranteeing little air quantity, the utility model provide a kind of be applicable to temperature and little apparatus for measuring air quantity have that spiral mixes and the air conditioner air-out measurement mechanism of pipe sampling mechanism.
The technical solution that realizes above-mentioned purpose is such:
1, the air conditioner air-out measurement mechanism that has spiral mixing and pipe sampling mechanism, comprise airtight air compartment, temperature mixed organization, temperature sampling mechanism, it is characterized in that: described temperature mixed organization and temperature sampling mechanism comprise diversion cavity, cylindrical diversion section 4 and sampling assemble 5;
Described diversion cavity comprises that circular front end plate 1, guide vane 2 and the guide vane of air channel demarcation strip more than 3,6 are distributed on the circular front end plate 1, form a ring-type air intake passage; Air channel demarcation strip 3 is adjacent with guide vane 2, and is parallel to circular front end plate 1, and demarcation strip 3 middle parts in air channel have air outlet; Connecting cylindrical diversion section 4 on the air outlet of air channel demarcation strip 3; Sampling assemble 5 comprises stopple coupon, adapting pipe and humiture sampling box; Stopple coupon one end of sampling assemble 5 stretches to cylindrical diversion section 4, uniform fresh air inlet on the inserting end tube wall of stopple coupon, and the other end of stopple coupon connects adapting pipe and humiture sampling box, carries out the measurement that air conditioner goes out wind-warm syndrome, humidity in sampling box.
2, according to above-mentioned 1 described air conditioner air-out measurement mechanism, it is characterized in that with spiral mixing and pipe sampling mechanism:
Wind speed is 0.5m/s-5m/s in described ring-type air intake passage, the cylindrical diversion section 4,
Fresh air inlet diameter in the described sampling assemble 5 on the stopple coupon is Φ 9mm-Φ 12.4mm,
Described cylindrical diversion section 4 with the diameter proportion pass of stopple coupon 5 is: (3-6): 1.
Useful technique effect of the present utility model is embodied in following a few each side:
1, the utility model is by the improvement to existing temperature mixed organization and temperature sampling mechanism, distribution uniformly of each diversion cavity and fairshaped design have reduced the resistance of mixing arrangement, and because the design of its symmetry, each chamber resistance is identical, and then the air mass flow of feasible each diversion cavity of flowing through can reach equilibrium state automatically, and is therefore more even through the wind speed profile behind each chamber, temperature is also more even, has improved measuring accuracy.
2, this measurement mechanism after the improvement, the size of its mixed organization and sampling mechanism is corresponding to be reduced, and material uses corresponding reduction, has reduced manufacturing cost simultaneously, has reduced the accumulation of heat of material, the operating mode that easier acquisition is stable.
3, the utility model is applicable to air conditioner leaving air temp and little apparatus for measuring air quantity
