Working condition requirement, requires larger unit especially for some moisture removals, quilt is improved by changing evaporator air outlet air quantity
The service behaviour and security performance of test-run a machine group, and then improve the measuring accuracy of subject unit.
(2) the bypass air-valve is mainly enabled when air dewetting effect is inapparent, passes through the bypass air-valve
The air quantity for passing through the evaporator is reduced, realize air with small air quantity by the evaporator, with further enhancing steaming
Send out the effect of device effect on moisture extraction.
(3) such as when 2 DEG C/1 DEG C of wet and dry bulb temperature between enthalpy difference experiment room is tested, the evaporator plate pipeline section is easy to knot
Frost, when evaporator plate pipeline section frosting, opens the preposition electric heater and carries out the pre-heat treatment to air, steamed so that blowing
Frost on evaporator plate pipeline section is melted removing by the hot blast sent out in device coil section, and air cooling is removed while can also improve evaporator
Wet effect.
(4) heretofore described evaporator uses combined type caliber：It is gas-liquid two-phase, institute in the total feed tube of refrigerant
State and there was only gas phase in the total gas collection outlet of refrigerant, so the diameter of the total feed tube of the refrigerant is set smaller than into the system
The diameter of copper pipe is minimum in the caliber of the total gas collection outlet of cryogen, the evaporator.The combined type caliber is by controlling steaming
Send out the total feed tube caliber of device and be less than total gas collection outlet caliber, in the case that total feed tube caliber is small, the gas-liquid two-phase system of entrance
Cold appropriate dosage, is further further separated into the smaller copper pipe of caliber, and total gas collection outlet caliber is big, is conducive to fully quick row
Go out the refrigerant vapour that the vaporization of evaporator inner refrigerant is produced, it is therefore prevented that the refrigerant vapour aggressiveness that vaporization is produced is in evaporator
Portion improves evaporator heat exchange performance so as to hinder the efficiency of refrigerant vaporization.
The arrangement of the combined type caliber and the copper pipe can be realized under conditions of identical windward side air mass flow,
Heat exchange amount is improved, and is significantly reduced by the air drag of evaporator plate pipeline section, in other words the present invention can be met by changing
Wind face air mass flow improves evaporator heat exchange performance.
(5) throttling element that the magnetic valve adds expansion valve to constitute can make the requirement of the sufficient cold operation of vapourator full, described
Magnetic valve, expansion valve may be mounted in the unit box body.
(6) first drip tray is used to collect the condensed water at the dry saturated steam humidification jet pipe, second drip tray
For collecting the condensed water that air is formed after cooling and dehumidifying at the evaporator, first drip tray, the second drip tray are equal
It is obliquely installed, in order to which the condensed water being collected into is completely exhausted out in unit box body by drainage pipeline.
(7) the front-mounted heating unit has the effect of defrosting, meets different subject units between the test of enthalpy difference experiment room
Humiture requirement, improve measuring accuracy while also achieve energy-conserving and environment-protective.Meet people (special to various operation of air conditioning systems
It is not more than 130kW units) performance test system is stable, the requirement of energy-saving run, can produce huge social benefit.After described
Electric heater is put such as to be made up of 45kW adjustable electric heating unit and 15kW fixation electric heating unit, so can be by adjusting
The power of adjustable electric heating unit is saved to meet the temperature requirement that subject unit is different, and temperature adjustment is precisely, using scope more
Extensively.The protection switch or pressure difference switch are to be used to protect electric heater, to prevent electric heating tube from occurring dry combustion method.
(8) present invention, which fully takes into account, is recycled the energy in enthalpy difference experiment room, such as the present invention passes through water
Pump is connected Surface cooling coil section with surface cooler heat exchanger tube, and the Surface cooling coil section utilizes condensed water in the surface cooler copper pipe
Heat the air is preheated again, it is possible to reduce electricity in preposition electric heater input, the present invention more meets section
The requirement of energy environmental protection.

Carry out entering evaporator 4 after preheating again, because required moisture removal is smaller, now exports air-valve 16 and open, bypass air-valve 6 is closed
Close, air after cooling and dehumidifying, is heated to reach required temperature, then added by dry saturated steam in evaporator 4 into rearmounted heater 7
The humidification of wet shot pipe 5 reaches required humidity, and air has reached the humiture requirement of subject unit after a series of processing, through blower fan
In 8 feeding enthalpy difference experiment room tests, so circulation.
When the moisture removal required by subject unit is larger：Air is by the primary efficient filter screen of return air inlet 1 filtering dust
Preheat afterwards into preposition electrical heating 3, subsequently into Surface cooling coil section 15 by the waste heat that is reclaimed in Surface cooling coil section 15 to air
Carry out entering evaporator 4 after preheating again, because required moisture removal is larger, the now adjustment outlet open degree of air-valve 16, bypass
Air-valve 6 is opened, and the baffle plate of outlet air-valve 16 covers the part air outlet of evaporator 4 and air outlet is diminished, and is entered by return air inlet 1
Partial air in unit box body is directly discharged by bypassing air-valve, and the air quantity of evaporator air outlet reduces, with small air quantity, big enthalpy
The mode of difference realizes the efficient cooling and dehumidifying of air, heats to reach required temperature subsequently into rearmounted heater 7, then by dry
The humidification of steam humidification jet pipe 5 reaches required humidity, and air has reached the humiture requirement of subject unit after a series of processing,
Through in the room test of the feeding enthalpy difference experiment of blower fan 8, so circulating.
