Description
Technical field
The utility model relates to a kind of environment measuring device, is specifically related to a kind of heat recovery wind-cooled cold-water unit environmental simulation proving installation.
Background technology
Cooling-water machine is a kind ofly to reach the unit of refrigeration through both vapor compression or absorption circulation, the wind-cooled cold-water machine be directly by air as heat eliminating medium, the condensing coil of machine is directly expelled the cooling of heat atmospheric air, is widely used in air-conditioning, industrial refrigeration field.Because the wind-cooled cold-water unit is sold to ground such as the Middle East, Africa in a large number; Because zonal difference causes environment temperature different, for example: during summer; The environment temperature on ground such as the Middle East, Africa generally reaches more than 40 ℃, and the environment temperature in Guangdong generally only reaches about 30 ℃.Therefore when the wind-cooled cold-water unit is tested, often can not reach the desired environment temperature of test, can not measure the True Data of unit, obtain the actual performance of unit, so that make improvement.
Summary of the invention
The utility model overcomes the deficiency of prior art; A kind of heat recovery wind-cooled cold-water unit environmental simulation proving installation is provided; The heat that discharges through wind-cooled cold-water unit to be tested comes the temperature in the modifier; The appropriate environments temperature is provided, reaches the required environment temperature of test, energy-conserving and environment-protective simultaneously, cost are low.
The technical scheme of the utility model is following: heat recovery wind-cooled cold-water unit environmental simulation proving installation, be divided into two zones, and the zone on an outer limit is measurand main frame zone; Another zone inside is a stub area; Structure controls device, automaton and HRU by attemperator, air exhausting device, air-returning device, end equipment, temperature to be formed, and said air exhausting device, air-returning device are connected with automaton through the air lock switch, and air exhausting device is arranged on top; Air-returning device is provided with both sides, the left and right sides; Link to each other with temperature control device, said HRU is placed on the exhaust outlet place, and end equipment is positioned at stub area.
Said attemperator mainly is made up of L type groove and cystosepiment, and said cystosepiment is by thick foam of 30mm of two panel beating sandwich, plays insulation effect, prevents that heat runs off.
Said air exhausting device, air-returning device are formed by air lock, the environment temperature that the scalable test is required.
Said HRU structure is made up of coil pipe and pipeline, is placed on the air exhausting device mouth, can be partially recycled unnecessary heat, and improve the temperature of chilled water, thereby reach the operating mode of shell and tube evaporator water inlet.
The attainable beneficial effect of the utility model is: utilize the heat that unit discharged to be tested to stablize the inflow temperature of shell and tube evaporator; Reach test required environment temperature and inflow temperature; The test noise is low, not only need not to establish cooling column in addition, reduces cost; Heat reusable edible simultaneously reaches environmental protection, energy-conservation characteristics.
Description of drawings.
Fig. 1 is the agent structure synoptic diagram of the utility model, and among the figure, 1 is HRU, and 2 is air exhausting device, and 3 is air-returning device, and 4 is automaton, and 5 is attemperator, and 6 is the main frame zone, and 7 is end equipment, and 8 is temperature control equipment.
Embodiment.
Be described further below in conjunction with the embodiment of accompanying drawing the utility model.
As shown in Figure 1; Heat recovery wind-cooled cold-water unit environmental simulation proving installation, said air exhausting device (2), air-returning device (3) are connected with automaton (4) through the air lock switch, and air exhausting device (2) is arranged on top; Air-returning device (3) is provided with both sides, the left and right sides; Link to each other with temperature control device (8), said HRU (1) is placed on air exhausting device (2) mouthful place, and end equipment (7) is positioned at stub area.
The embodiment of the utility model is following.
When carrying out temperature test; Earlier wind-cooled cold-water unit to be tested is placed on the host test zone; Couple together with end equipment, before the start test, earlier the door in the heat recovery wind-cooled cold-water unit environmental simulation proving installation is closed; Air draft air lock, return air air lock, new wind air lock all turn down; Preestablish an environment temperature, automaton can be controlled the switch of all air locks and the amplitude of switch is regulated the temperature in the heat recovery wind-cooled cold-water unit environmental simulation proving installation according to this design temperature, reaches the environment temperature that sets.Unnecessary heat can be absorbed by HRU, is used for the water temperature of constant entering shell and tube exchanger.
For example: as shown in the figure: the temperature in heat recovery wind-cooled cold-water unit environmental simulation proving installation is too high, and when being higher than the environment temperature that sets, the air lock of air exhausting device (2) can be held greatly, and new wind air lock is opened greatly, and the air lock of air-returning device (3) turns down; Temperature in heat recovery wind-cooled cold-water unit environmental simulation proving installation is not high enough, and when being lower than the environment temperature that sets, the air lock of air exhausting device (2) turns down, and new wind air lock turns down, and the air lock of air-returning device (3) is opened greatly.Control the temperature in the heat recovery wind-cooled cold-water unit environmental simulation proving installation through such mode, reach the environment temperature of our required test.And in the unnecessary heat of air exhausting device discharging, some is through HRU (1), and another part be directly give off outdoor.
