Problems solved by technology

[0005] Since the cooling rate (i.e. the time it takes for the interior of the adiabatic cavity to cool from its maximum temperature to its minimum temperature) is actually a very critical factor, the cooling capacity provided by the refrigeration unit for the time required to maintain the minimum set temperature was found to be only A modest percentage (approximately 10%) of the cooling capacity provided by the cooling step, thus leading to a second, much more serious problem in terms of

Embodiment Construction

[0026] exist figure 1 Among them, the hydrodynamic circuit of the low-temperature stage is generally indicated by 100, and can use, for example, R23 (ie trifluoromethane) as the refrigerant medium. The circuit includes the following components:

[0027] An evaporator 110 consisting of a set of finned tubes arranged in the adiabatic cavity 10 of the climatic chamber behind a baffle 12 for deflecting the air flow. In a manner known per se, a set of electric heating elements 14 (actually, a set of armored resistance heating elements arranged in parallel) is also provided in the cavity 10, the setting and control of the maximum temperature and the minimum setting Probe 16 of an adjustable thermostat 15 for a fixed temperature, a safety thermostat 17 for a defined temperature, an impeller 18 of an electric fan 19 adapted to provide regular air flow in the cavity 10. An adjustable thermostat 15 is provided outside the cavity 10 and is associated with a PLC 25 that controls the ent...

Abstract

Climatic test chamber (10) for carrying out a sequence of specified test cycles and cooled by means of at least a refrigerating circuit (100, 200, 410) including a variable-speed compressor (120, 210, 410). During the steps of the test cycles in which said chamber (10) is held at a minimum set temperature, the compressor (120, 210, 410) operates at the minimum rotating speed thereof and the refrigeration capacity is used to cool a cold storage medium. The cold stored by the cold storage medium is then recovered to subcool the refrigerant medium during the cooling-down steps in which the compressor (120, 210, 410) operates at the maximum rotating speed thereof.

Description

technical field [0001] The present invention relates to a climatic chamber used in test laboratories to subject material and / or component samples to a defined number of temperature cycles, the samples being suitably loaded and arranged in an insulated cavity. Background technique [0002] These temperature cycles consist of alternating heating and cooling steps, with periods of predetermined length in between, during which the samples are kept at a maximum and minimum temperature, where in each case the temperature involved Values ​​are provided by the test specification associated with the material and / or component being tested. [0003] Although there are no particular problems in reaching and maintaining the maximum temperature, although this temperature can reach +180 ℃, the use of traditional electric heating elements of high power level or low power level is sufficient for this purpose, and the reduction to the required The use of the minimum temperature, that is, the...
