Abstract
The utility model relates to an energy saving box with constant humidity and temperature, and is characterized in that a heater is a combination heater, which is composed of an electric heater and a semiconductor refrigerator; a humidifier is a combination humidifier, which is composed of an electric humidifier and an ultrasonic humidifier. The utility model has the advantage of combining energy saving and controllability together, which effectively overcomes the phenomenon that temperature or humidity in the existing homogeneous damp-heat box overshoots during heating or humidifying processes, improving test efficiency.
Description
The utility model relates to a kind of environmental test equipment, particularly a kind of energy-saving constant-temperature constant-moisture chamber.
Moisture-heat test-box commonly used, by having or not refrigeration compressor can divide two classes, refrigerating capacity and the amount of drying and heating, the heating of humidifier generation and wet, the temperature that the balance between the humidification amount is come the regulating and controlling chamber that the former utilizes compressor to produce, so controllability is good, but cost, energy consumption height are arranged, deficiency such as noise, volume are big.The latter then utilizes heating, humidification amount and casing natural heat dissipation amount and the balance of air moisture between the condensation number of tank wall face, control the temperature and humidity of test, have cost, energy consumption is low, advantage such as noise, volume are little, but, only rely on natural equilibrium and regulate, thereby in heating, humidification because the damp and hot case of this class all adopts the heating and the humidifier of single type, very easily produce the overshoot phenomenon of temperature, humidity, cause controllability relatively poor.Inwall because of existing damp and hot case is single atresia panel again, certainly will produce condensation at wall as the tank wall insulation is bad, influences test effect.
The purpose of this utility model is the above-mentioned deficiency that will overcome the existing damp and hot case of no refrigerant compression, and a kind of simple in structure and energy-saving preferably steady-state damp heat test case of controllability is provided.
This programme has been done rational improvement to the well heater and the humidifier of the existing damp and hot case of no refrigeration compressor, promptly uses compound well heater of being made up of electric heater and semiconductor cooler and heating and the humidifier that is substituted the single type in the present similar damp and hot case by the compound humidifier that electric moistening device and ultrasonic humidifier are formed.Its objective is the part heat the when dual nature of utilizing semiconductor cooler to have heating and refrigeration also can absorb humidification, utilize ultrasonic humidifier when humidification, can absorb the characteristic of a large amount of heats, improve the balance quality between heating, humidification amount and casing natural heat dissipation amount and the wall hydrogenesis amount, thereby overcome the humidity in heating, humidification, the humidity overshoot phenomenon reaches the purpose of improving adjustability.In order further to improve the test effect of damp and hot case, this programme also in casing list inwall periphery, has been set up the bee-hole clamping plate, to constitute the ventilation interlayer in the case, make that air and interlayer air are exchanged in the case, be incubated the more deficiency of condensation when bad thereby can overcome because of tank wall.The well heater that is characterised in that of the present utility model is the compound well heater of being made up of electric heater and semiconductor cooler, and humidifier is the compound humidifier of being made up of electric moistening device and ultrasonic humidifier.Cabinet wall has the ventilation interlayer that is made of single inwall and bee-hole clamping plate.
The utility model has the advantages that collection energy saving and controllability are better than one, advantage such as both kept that the agent structure of existing similar damp and hot case and cost, energy consumption are low, noise, volume are little, overcome the overshoot phenomenon of temperature, humidity again, improved tunable performance, improved test effect.And, simple in structure, implement to have good practical values easily.
Below, will be in conjunction with the accompanying drawings and by embodiment, the utility model is further described.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an electrical schematic diagram of the present utility model.
With reference to accompanying drawing: the utility model comprises casing 1, controller 2, well heater 3, humidifier 4.Described casing list periphery of inner wall is provided with bee-hole clamping plate 5, to constitute a ventilation interlayer.Other structure of casing comprises that chamber door, blower fan, heat-insulation layer etc. are all identical with existing like product about parts and their set-up mode.Well heater of this programme and humidifier branch are located at the casing upper and lower sides, wherein, well heater is formed a compound well heater by electric heater 6 and semiconductor cooler 7, and humidifier is made up of electric moistening device 8 and ultrasonic humidifier 9, one compound humidifier, their group number can be pacified to be needed to be provided with.The principle of work of this programme is: configuring test temperature T
G, humidity T
WAnd behind the heat-insulation preheating time t, damp and hot case begins heating with full power and heats up, when the temperature inside the box rises to T
G-△ T
G(△ T
GBe the control temperature difference) after, controller will cut off some groups of well heaters automatically, and only surplus one group of well heater is kept the temperature inside the box, and behind time t, humidifier begins the total power humidification, meanwhile, and semiconductor cooler place refrigerating state, humidity is T in case
W-△ T
W(△ T
WFor controlled humidity poor) time, controller will cut off some groups of humidifiers, and make wherein one group of humidifier and semiconductor cooler work, make that humidity slowly reaches setting humidity in the case, after this, semiconductor cooler quits work.In above-mentioned heating, humidification, because the part heat that humidifier increases will be offset by the refrigerating capacity of semiconductor cooler, and ultrasonic humidifier itself can the absorption portion heat, thereby can avoid the humidity overshoot phenomenon.Again because the heat that adds of well heater is only enough kept oven temperature, in the temperature range of setting, thereby can avoid the temperature overshot phenomenon that causes because of heating power is excessive.The controller of present embodiment is selected TP801 type temperature, humidity program control instrument for use, and semiconductor cooler is the CH112703 type, and ultrasonic humidifier is the D200 type, and electric heater is TRD.
