Abstract
Description
Technical Field
[0001] The invention relates to the field of testing, in particular to a testing laboratory. Background Art
[0002] Drying devices are generally divided into two types on the market: open and closed. The open type means that the air in the drying device is heated to evaporate the water into the air continuously, while the closed type means that the air in the drying device is heated to evaporate the water, and then the water is condensed to remove it. The two important components required for these two methods are the evaporator and the condenser. In the field of drying, the evaporator is a component used to cool and condense the air to remove moisture, while the condenser is a component that heats the air to the outside by condensing the medium inside itself. When manufacturing the drying device, in order to ensure the quality of the drying device, the parameters of the condenser and the evaporator need to be tested. In the prior art, since the evaporator and the condenser have different environmental requirements, the way to test them is to establish two different test chambers, and then give each test chamber the required temperature and humidity at one time, resulting in high energy consumption, and the heating device or cooling device and humidifying device used to provide temperature and humidity are under heavy load, resulting in a reduced service life of the components, and multiple test chambers are required for testing, and the manufacturing cost is also high. Summary of the invention
[0003] In order to solve the above technical problems, the object of the present invention is to provide a test laboratory with a small load and capable of testing the evaporator and the condenser at the same time.
[0004] The technical solution adopted by the present invention to solve the above problems is: a test laboratory, comprising:

[0027] Reference Figure 1 , a testing laboratory, including:
[0028] Test room 10;
[0029] A primary environment providing device 20, the primary environment providing device 20 is connected to the test room 10, and the primary environment providing device 20 is used to provide a first level environment in the test room 10;
[0030] The detection chamber 30 is located in the test chamber 10. The detection chamber 30 includes an air inlet 31 and an air outlet 32. The air inlet 31 is connected to the test chamber 10, and preferably the air outlet 32 is also connected to the test chamber 10;
[0031] A secondary environment providing device 40, which is disposed at the front end of the detection chamber 30 and is used to provide a final test environment in the detection chamber 30;
[0032] A test station 50, the test station 50 is located in the detection chamber 30, the test station 50 is used to place the object to be detected, and the test station 50 is located behind the secondary environment providing device 40;
[0033] A wind tunnel module 60, wherein the wind tunnel module 60 is disposed in the detection chamber 30, and the wind tunnel module 60 is used to drive the air in the test chamber 10 into the detection chamber 30;
[0034] An enthalpy difference tester is located before and after the test station 50 , and is used to test air parameters before and after the test station 50 .
[0035] By setting up a detection room 30 in the test room 10, and then providing an intermediate environment to the test room 10 through a primary environment providing device 20 outside the test room 10, the wind tunnel module 60 in the detection room 30 drives the first-level environmental air in the detection room 30 to enter the detection room 30. When the air of the first-level environment enters the detection room 30, the air parameters will be further changed through the secondary environment providing device 40, so as to achieve the air environment we need, and the items to be tested are placed on the test station 50. The air with completed parameter changes passes through the items to be tested on the test station 50. At the same time, the air parameters before and after the test station 50 are tested by an enthalpy difference tester, and then calculated to obtain the parameters of the items to be tested. By providing multiple levels of environment, the environment does not need to be provided all at once, which effectively reduces the load on the components providing the environment. Moreover, parts that require different environments for testing can be placed in a test chamber 10, and an air environment with intermediate parameters can be provided by a primary environment providing device 20. Then, the air environment with intermediate parameters can be transformed differently by secondary environment providing devices 40 in different test chambers 10, so as to test parts that require different environments.
[0036] For further improvement, the primary environment providing device 20 is a temperature controller and / or a humidity controller. The temperature controller is used to control the temperature in the test chamber 10, and the humidity controller is used to control the humidity in the test chamber 10. The settings are made according to the environment required when we actually test the product. Preferably, both the temperature controller and the humidity controller are set.
[0037] Considering that we prefer to test the evaporator and condenser on the drying device, further improvements are made, and the secondary environment providing device 40 is a temperature control component and / or a humidifier, and the temperature control component and the humidifier can be selected to be arranged in the detection chamber 30. The preferred temperature control component is a water coil and / or an electric heater, and only one of them can be arranged in the detection chamber 30, or both can be installed in the test chamber. The temperature control component can also be selected to be used in combination with a condensing device and a flame heater. The specific structure of the temperature control component can be selected according to actual conditions, and its type is not limited.
[0038] When the condenser needs to be tested, the air parameter we need is low temperature. At this time, if the outside temperature is high, we first use the temperature controller to initially cool down the temperature in the test chamber 10, and then the temperature control component of the secondary environment providing device 40 works, and the air is further cooled by the temperature control component to reach the temperature we need. If the indoor temperature is not high, we can choose not to work the primary environment providing device 20, and only start the secondary environment providing device 40 to adjust the air in the detection chamber 30.
[0039] When the evaporator needs to be tested, the air parameters we need are generally high temperature and high humidity. For example, if a high temperature of 75 degrees and a humidity of 80% are required, we can first increase the temperature in the test chamber 10 to 45 degrees and the humidity to 50% through a temperature controller and a humidity controller. Then the wind tunnel module 60 drives the air in the test chamber 10 to flow into the detection chamber 30. When passing through the secondary environment providing device 40, the air parameters are further adjusted through the temperature control component and the humidifier on the secondary environment providing device 40 to achieve a high temperature of 75 degrees and a humidity of 80%.
[0040] For further improvement, considering that each detection chamber 30 is preferably used to test only one product to ensure efficiency and stability, and when testing the evaporator, the humidity requirement is higher, and when testing the condenser, the humidity requirement is lower, and considering the cost issue, it is preferred that two detection chambers 30 are provided in the test chamber 10, and the secondary environment providing device 40 in one detection chamber 30 is a water coil, an electric heater and a humidifier, and the secondary environment providing device 40 in the other detection chamber 30 is an electric heater, so that different detection chambers 30 are selected according to actual conditions.
[0041] When the evaporator and condenser need to be tested at the same time, that is, there is a demand for both high-temperature working conditions and low-temperature working conditions, we start the two test chambers 30 at the same time. The test chamber 10 provides a specific environment through the primary environment providing device 20. The different working conditions required by the evaporator and condenser are adjusted differently by the secondary environment providing device 40 in the two test chambers 30 to create different working conditions.
[0042] Of course, we can also choose the primary environment provided by the primary environment providing device 20 as the minimum temperature standard for testing the evaporator and condenser. For example, when the evaporator requires a high temperature of 75 degrees and a humidity of 80%, and the condenser requires a low temperature of 20 degrees and a humidity of 40%, we can choose the primary environment providing device 20 to directly provide a temperature of 20 degrees and a humidity of 40%, thereby directly meeting the test requirements of the condenser, so that the secondary environment providing device 40 in the detection chamber 30 of the test condenser does not need to work, and only the secondary environment providing device 40 in the detection chamber 30 of the test evaporator needs to work, so that the secondary environment providing device 40 may not even be set in the detection chamber of the test condenser.
[0043] As a further improvement, the wind tunnel module 60 is preferably arranged behind the test station 50. The wind tunnel module 60 is preferably an air volume static pressure regulating system. The air volume static pressure regulating system is a commonly used wind tunnel module 60 and will not be further described here.
[0044] Considering that the wind tunnel module 60 may also generate heat when in use, thereby affecting the test effect of the enthalpy difference tester, it is preferred that the wind tunnel module 60 is disposed behind the enthalpy difference tester.
[0045] As a further improvement, in order to facilitate the adjustment and use of the detection chamber 30, a movable roller is preferably provided at the bottom of the detection chamber 30, so that the detection chamber 30 can be pushed out of the test chamber 10 or pushed into the test chamber 10 when needed.
[0046] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or directly or indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
