Fig. 1 has illustrated the present invention to carry out the integral layout of facility.
Fig. 2 has illustrated of the present invention a kind of the most basic and freeze easily and heat the power test circuit.
The space, indoor of R1-simulation; The space, outside of R2-simulation; The L-connecting leg; K1-is as the hold concurrently indoor transducer air conditioning of proving installation of temperature control; K2-is as the hold concurrently outside transducer air conditioning of proving installation of temperature control; The off-premises station of F1 and F2-transducer air conditioning; P-power test circuit part; The A-reometer; The V-voltage table; The B-tested air conditioner; 1 and 6-atmospheric environment point for measuring temperature; 2-indoor point for measuring temperature; 3-indoor hygrometric point; 4-outside point for measuring temperature; 5-outside hygrometric point; 7-is incubated heat insulation layer.
Among Fig. 1:
Space, indoor " R I " and space, outside " R2 " are two adjacent test spaces, and insulation heat insulation layer " 7 " surrounds around it; Two cover transducer air conditionings " K1 " and " K2 " place respectively among these two test spaces " R I " and " R2 "; Tested air conditioner " B " is placed in the middle of the partition wall.The nominal power of two cover transducer air conditionings " K1 " and " K2 " all should be greater than the nominal power of tested air conditioner.
In addition, in space, indoor " R I ", also be provided with measuring point " 2 " and " 3 " of its medial temperature of reflection and humidity; In space, outside " R2 ", also be provided with measuring point " 4 " and " 5 " of its medial temperature of reflection and humidity; Near the off-premises station of two transducer air conditionings " K1 " and " K2 " difference correspondence, an atmospheric environment point for measuring temperature " 1 " and " 6 " have respectively been established again.
Preliminary work before tested air conditioner " B " being implemented refrigeration work consumption (amount) or being heated power (amount) test mainly is:
The wet cooling condition that removes by two transducer air conditionings " K1 " and " K2 " carries out dehumidifier to two test spaces " R I " and " R2 " respectively; The control point of dehumidifier is: hygrometric point " 3 " and " 5 "; The requirement that dehumidifier reaches should be: after the whole test period to tested air conditioner " B " in, must not have condensate water to separate out.
--tested air conditioner " B " is in the use of its later daily cooling and constant temperature, it is very little that the refrigerating capacity of making condensate water accounts for the score of overall refrigerating effect, therefore, purpose is in the test event of testing total refrigeration work consumption (amount), the present invention very easily causes the key element of the condensate water amount of separating out of test error thoroughly to root out this, prerequisite is to increase preceding " dehumidifying " preparation process of test, and, in this present invention distinctive " dehumidifying " preparation process, single with regard to the prior art of " dehumidifying ", it in an application of the invention, be to reach fully: allow tested air conditioner " B " in the test overall process, this not high minimum requirement that evaporated condensation water is separated out.
When testing the refrigeration work consumption (amount) of tested air conditioner " B ":
The work of transducer air conditioning " K1 " is set in heating condition in the space, indoor " R I ", offset the tested air conditioner " B " of having started shooting refrigerating capacity to space, indoor " R I " input with its heating capacity, and, guarantee that medial temperature point for measuring temperature " 2 " temperature displayed in the space, indoor " R1 " is stabilized in above the temperature T 1 (27 ℃); And the work of transducer air conditioning " K2 " is set in cooling condition in space, outside " R2 ", offset the condensation waste heat amount of tested air conditioner " B " discharge of having started shooting with its refrigerating capacity, and, guarantee that medial temperature point for measuring temperature " 4 " temperature displayed in the space, outside " R2 " is stabilized in above the temperature T 2 (35 ℃).
--the heating capacity of the transducer air conditioning " K1 " that measure this moment just equals the refrigerating capacity of tested air conditioner " B " under operating mode T1 and T2 condition.
--above-mentioned medial temperature point for measuring temperature " 2 " and " 4 ", also can put and replace by temperature-sensitive in the machine in two transducer air conditionings " K1 " and the transducer air conditioning " K2 ", at this moment, should take into account the temperature difference factor after replacing.
When the test tested air conditioner " B " heat power (amount) time:
The work of transducer air conditioning " K1 " is set in cooling condition in the space, indoor " R I ", offset the tested air conditioner " B " of having started shooting heating capacity to space, indoor " R I " input with its refrigerating capacity, and, guarantee that medial temperature point for measuring temperature " 2 " temperature displayed in the space, indoor " R1 " is stabilized in above the temperature T 3 (20 ℃); And the work of transducer air conditioning " K2 " is set in heating condition in space, outside " R2 ", offset the useless cold of evaporation of tested air conditioner " B " discharge of having started shooting with its heating capacity, and, guarantee that medial temperature point for measuring temperature " 4 " temperature displayed in the space, outside " R2 " is stabilized in above the temperature T 4 (7 ℃).
--the refrigerating capacity of the transducer air conditioning " K1 " that measure this moment just equals the heating capacity of tested air conditioner " B " under operating mode T3 and T4 condition.
--above-mentioned medial temperature point for measuring temperature " 2 " and " 4 ", also can put and replace by temperature-sensitive in the machine in two transducer air conditionings " K1 " and the transducer air conditioning " K2 ", at this moment, should take into account the temperature difference factor after replacing.
Fig. 2 has mainly illustrated the basic circuit of power test circuit part " P ".
The first test connectivity scenario:
Power test circuit part " P " is connected across transducer air conditioning " K1 " and power supply between the two, so, the long-pending AV of data A that reometer " A " and voltage table " V " are shown and B just equals the power of transducer air conditioning " K1 " (off-premises station " F1 " that comprises it) complete machine.
When test tested air conditioner " B " refrigerating capacity (power) N1:
Transducer air conditioning " K1 " is to heat power AV with its heat pump to offset tested air conditioner " B " refrigeration work consumption N1, and, the medial temperature in space, indoor " R I " is stabilized in above the T1.
Then: N1=AVE2
E2: the coefficient of performance of transducer air conditioning " K1 " when heat pump heats.
When test tested air conditioner " B " heating capacity (power) N2:
Transducer air conditioning " K1 " is to heat power N2 with what its refrigeration work consumption was offset tested air conditioner " B ", and, the medial temperature in space, indoor " R I " is stabilized in above the T3.
Then: N2=AVE1
E1: the Energy Efficiency Ratio during transducer air conditioning " K1 " refrigeration.
In test process, the temperature when point for measuring temperature " 2 " and " 4 " shows: be stabilized in T1 and T2 (refrigeration); Perhaps when T3 and T4 (heating), reometer " A " and voltage table " V " also can be stabilized in above the some separately numerical value.Therefore, whether stable by the display digit of observing reometer " A " and voltage table " V ", whether the temperature that equally also can judge point for measuring temperature " 2 " and " 4 " shows stable.
The display digit of above-mentioned reometer " A " and voltage table " V " must could be approved and they be noted after they tend towards stability, and carries out the reckoning foundation of relevant power as measured data.
Certainly, also can replace reometer " A " and voltage table " V " in above-mentioned power test circuit " P " part, can directly obtain magnitude of power equally with power meter.
When the refrigerating capacity of surveying and calculate tested air conditioner " B " and heating capacity, when the Energy Efficiency Ratio of employing transducer air conditioning " K1 " and the coefficient of performance, also need to consider the residing at that time atmospheric environment temperature of off-premises station " F1 " of this transducer air conditioning " K1 ", that is: the temperature variation of point for measuring temperature " 1 " (example: summer in winter atmospheric temperature difference) is to the problem that influences of transducer air conditioning " K1 " E1 and E2, this problem can solve by actual measurement, that is: in different temperature ranges, allow E1 and E2 be multiplied by a different temperature correction coefficient again.
To the roughly the same test and measuring of transducer air conditioning " K2 ", can be used for checking above-mentioned measured value.
The second test connectivity scenario:
The input end of power test circuit part " P " directly with the pairing off-premises station of transducer air conditioning " K1 " " F1 " in the frequency-changeable compressor connection.The long-pending AV of data A that reometer " A " and voltage table " V " are shown and B equals the power of frequency-changeable compressor.The AV of this moment with: in the transducer air conditioning " K1 " to little power of fan Q1 of space, indoor " R I " blowing and the big blower fan Q2 in the off-premises station " F1 ", and automatically controlled power Q3 is all irrelevant.
When test tested air conditioner " B " refrigerating capacity (power) N1:
Then: tested air conditioner " B " refrigeration work consumption N1=AVE2+Q1
E2: transducer air conditioning " K1 " does not relate to the coefficient of performance of Q1, Q2 and Q3 when heat pump heats.
When test tested air conditioner " B " heating capacity (power) N2:
Then: tested air conditioner " B " heats power N2=AVE2-Q1
E1: the Energy Efficiency Ratio that does not relate to Q1, Q2 and Q3 during transducer air conditioning " K1 " refrigeration.
All the other items are all identical with the first test connectivity scenario.
The measuring accuracy of above-mentioned two testing schemes of the present invention can be obtained in actual measurement is checked with tested air conditioner " B " model machine of standard, also can examine out the test correction factor of above-mentioned two testing schemes simultaneously easily.
Owing to can therefore,, also be very desirable finally in the hope of the test correction factor of the inventive method if implement the above-mentioned first easier test connectivity scenario.
Because: this has reduced many troubles in operation;--the minimizing of required monitoring equipment and test data has just been created condition for reducing cumulative errors.Its measuring accuracy also is unlikely to and can difference arrives unallowed stage;--can obtain the test correction factor of the inventive method easily by the actual measurement of standard model machine, this has just created condition for primary goal of the present invention " simplification " and " cheapness " again.The final assembly cost that just can reduce test facilities to a great extent,--for can both setting up facility of the present invention, the technical supervising department (at county level) of basic unit and little medium-sized manufacturer created condition.
