A kind of energy-saving air conditioning device performance testing table, comprise indoor test bay 1 and outside test bay 3, also comprise between the air-treatment of indoor 2, between outdoor air is handled 4, circulation line and control system 19,2 between indoor test bay 1 and outside test bay 3 between the air-treatment of indoor, be respectively arranged with air door on its adjacent wall, 2 are provided with humidification system between the air-treatment of indoor, humidification system comprises electric moistening device 5 and mechanical spraying formula humidifier 6,2 adjacent walls are provided with pressure balance control system 9 between indoor test bay 1 and indoor air-treatment, this system comprises the differential air pressure sensor, blower fan and frequency converter, the differential air pressure sensor, blower fan and frequency converter link to each other with control system 19 respectively, be provided with in the outside test bay 3 and air-conditioning unit instruction carriage 11 and air sampling case 12, air sampling case 12 has last air outlet and following air inlet, the last air outlet of air sampling case 12 links to each other with the air outlet of air-conditioning unit instruction carriage 11, the following air inlet of air sampling case 12 links to each other with the air inlet of air-conditioning unit instruction carriage 11, the last air outlet of air sampling case 12 and following air inlet place are provided with the humiture sampling thief respectively, between outdoor air is handled 4 with outside test bay 3 and outdoor adjacent, be equipped with air inlet on the adjacent wall, air inlet is provided with thermal insulating door thermally insulated door, the thermal insulating door thermally insulated door place is provided with air-valve, air-valve links to each other with control system 19, wherein adjacent with outside test bay 3 air inlet is often opened, the air inlet adjacent with outside temperature outside is lower than 28 and opens when spending, and is respectively arranged with air processing machine 7 in indoor test bay 1 and the outside test bay 3,8.
Circulation line comprises main air duct 13, return airway 14, indoor circulation air path 15, indoor air processing machine circulation air path 16 and outdoor air processor circulation air path 17, main air duct 13 is positioned at indoor test bay 1, link to each other with the last air outlet of air sampling case 12 through pipeline, between the inboard air-treatment of return airway 14 junction chambers 2 and indoor test bay 1, link to each other with the following return air inlet of air sampling case 12 by the road, indoor circulation air path 15 connects main air duct 13, extend between the air-treatment of indoor 2 and outside test bay 3, between the air-treatment of indoor 2 and outside test bay 3 in air outlet is arranged, the air outlet place is provided with air-valve 10, air-valve 10 links to each other with control system 19, outdoor air processor circulation air path 17 junction chamber outer air processor 8 and outside test bays 3, the inboard air processing machine 7 of indoor air processing machine circulation air path 16 junction chambers and indoor test bay 1.
In order to be incubated to test bay, not influenced by ambient temperature, the top board of indoor test bay 1 and outside test bay 3 and the thickness of wallboard employing all around are 100 millimeters polyurethane foaming insulation board, the inside and outside laminate of warming plate is coated with the color steel of light colour, and indoor and outdoor side furred ceiling adopts light keel frame to join the porous aluminium sheet.Floor employing thickness is 150 millimeters polyurethane foaming insulation board, being coated with thickness above the floor is the anti-skidding Stainless Steel plate of 2mm, the bottom surface, floor is coated with the color steel that thickness is 0.8mm, for the color steel time that prevents from contacting with ground has been grown the generation corrosion, lay one deck damp proof insulation plastic sheeting on the surface of contact on floor and ground in advance.In order to make the big weight of floor bearing, lay the thick plank of one deck 9mm earlier above in the plate of storehouse, add wooden frame in proper width, again foaming processing together.This structure makes the test bay high insulating effect, is not subjected to the influence of outdoor environment, and constancy of test condition is good.
During system works, the processing of freezing of 8 pairs of air of air processing machine between outdoor air is handled in 4, by outdoor air processor circulation air path 17 air is sent into outside test bay 3, the cold air that circulation air path 15 shuntings in indoor come is inlet chamber outside test bay 3 also, finishes cold and hot Air mixing.If outside air temperature is lower than 28 ℃, between outdoor air is handled 4 with outdoor adjacent wall on thermal insulating door thermally insulated door open, suck outdoor cold air, mix with the hot-air in 4 between outdoor air is handled, and reaching the conservation measures that utilizes outdoor cold air to lower the temperature, control system 19 is regulated the cold and hot AIR Proportional that sucks by the air-valve that is located at the thermal insulating door thermally insulated door place.When working, opens the air door between the air-treatment of indoor on 2 walls, the air that enters from outside test bay 3 and the air that comes from 15 shuntings of indoor circulation air path carry out cold and hot mixing, humidification system adds wet process to it, with the air after handling in air door is sent into indoor test bay 1.7 pairs of indoor air of air processing machine in the indoor test bay 1 are heated.Differential air pressure sensor on the pressure balance control system 9 is gathered pressure difference signal, if indoor test bay 1 is excessive with the pressure reduction of outside test bay 3,9 work of electric control system 19 control pressure balance control system, fan operation is with 2 unnecessary air suction indoor test bay 1 between the air-treatment of indoor.
Because the thermal load of outside test bay 3 can be by the cold air cooling of lowering the temperature, so the refrigeration capacity of outside test bay 3 air processing machines of selecting for use 8 can reduce, test unit calculates according to refrigeration capacity test upper limit 60kW, select for use the refrigerating capacity of outdoor air treatment facility to be about 100kW to non-energy-saving test unit, and the airhandling equipment refrigerating capacity that energy-saving test unit is selected for use reduces to 70kW and can satisfy request for utilization, can reduce the cost of this airhandling equipment.
In order to verify the actual energy-saving effect of this test unit, insert three-phase voltage and three-phase current table at the test unit electrical control cabinet with electrical input, respectively KLD-40PQ air-conditioning unit has been done specified cooling condition test with two kinds of test methods (energy-conservation and non-energy saver mode) at Guangzhou China motor rail transport equipment Co., Ltd air conditioning test station, table (1) has recorded the operating condition of test condition and test figure is seen, table (2) has recorded voltage and reometer electricity consumption data.

b), after 4 coolings are dried between handling through outdoor air, become air condition point F, wet heating such as pass through again and handle the back and be the G point, control and reach outside air intake dry-bulb temperature (t
G=35 ℃, Φ ≈ 32%) requirement of numerical value regulation.According to pressure balance and flow conservation principle, should equal the air mass flow of return chamber inboard again from the air mass flow in the indoor inlet chamber outside, the air point G that returns through 2 spraying humidifications between the air-treatment of indoor after, constant enthalpy changes to air condition point H, be mixed into the I point with another fraction cold air that flows from the punishment of C point again, add wet process through 2 electric moistening devices between the air-treatment of indoor and (be approximately isothermal humidification, temperature has rising slightly) be the J point, heat to the A point through indoor air processing machine 7 again, control reaches indoor air intake dry-bulb temperature (t
G=29 ℃) requirement of numerical value regulation, finish an energy-saving air cyclic process.
Can calculate test unit actual power consumption power according to data in the table (2), its formula is
(kW)
In the formula: V-three-phase average voltage (V)
I-three-phase average current (A)
Table (2) power consumption tables of data
Energy-conservation test power consumption P
