RU2354890C1 - Unit of climate forming - Google Patents

Abstract

FIELD: heating.

SUBSTANCE: invention refers to equipment for testing various objects to effects of heat, cold and humidity. The unit of climate forming consists of a heater, a cooler, a humidifier and of a drier. The humidifier and drier are connected parallel between them. The heater and cooler are removed from a chamber and connected parallel between them. The humidifier and drier are connected successively with the heater and cooler.

EFFECT: elimination of effect of humidifier and drier to temperature mode of chamber.

Description

The proposed device relates to equipment designed to test various objects for exposure to heat, cold and moisture. For these purposes, heat, cold and moisture chambers are used.

Known chamber (Chamber of heat, moisture, cold. CM 30 / 75-80 TVX. LLC "SM Climate", St. Petersburg, pr. Nauki, 17A), in which a cooler, heater and dryer are located inside the chamber, and the humidifier is located outside. This design is the effect of the evaporator and dehumidifier on the temperature of the chamber and the need to remove condensed moisture on the dehumidifier from the chamber.In addition, the location of the cooler and heater in one volume, cooled to -70 and heated to +170 degrees Celsius, has a mutual negative effect on them work.

Known chamber (Test chamber. "Feutron Klimasimulation GmbH" Am Weberbrunnen 1, D-07975 Langenwetzendorf), which we choose for the prototype. In this chamber, the heater and cooler are located inside the chamber, and the humidifier and evaporator are parallel to each other and are located outside the chamber. The disadvantage of this device for the formation of climate is its effect on the temperature of the chamber.

In the proposed climate forming unit, the cooler and heater are removed from the chamber and connected in parallel, due to which one of them works depending on the required temperature, and the other is in the off state. As a result, this design eliminates the mutual negative influence of the cooler and heater. The humidifier and dehumidifier are also connected in parallel with each other and in series with the cooler and heater. As a result, the air flow circulating through the chamber passes through a heater or cooler and then through a humidifier or dehumidifier. As a result, the temperature of the air flow circulating through the chamber is automatically maintained in the humidifier and in the desiccant, and therefore they do not affect the temperature regime of the chamber.

The drawing shows a structural diagram of a climate formation unit, which consists of a heater 1 and a cooler 2 connected in parallel with each other. In series with a heater 1 and a cooler 2, a humidifier 4 and a desiccant 5 are connected.

The climate formation unit operates as follows. The air flow circulating through the chamber enters the inlet of the climate forming unit and, depending on the required temperature, is directed either through heater 1 or through cooler 2. The direction of air flow can be controlled, for example, by a damper 3, which opens the outlet of either heater 1 or cooler 2 Then, the air flow is either humidified in the humidifier 4, or dried in the dryer 5. In this case, the flow direction can be controlled by a shutter 6. Next, the air flow enters the outlet of the climate formation unit, and from there to the camera. To ensure air circulation through the climate forming unit, either a camera fan or an additional fan is used.

Claims (1)

Climate forming unit comprising a heater, cooler, humidifier and dehumidifier, wherein the humidifier and dehumidifier are connected in parallel with each other, characterized in that the heater and cooler are removed from the chamber and connected in parallel with each other, and the humidifier and dehumidifier are connected in series with the heater and cooler.
