Vortex Tube Refrigerator Apparatus From compressed air at ambient temperature and a high speed rotating vortex, the unit produces air temperatures down to -20Â °C, can perform 75 watts of cooling and discharges a hot air stream at up to 70Â °C.
The Vortex Tube Refrigerator Apparatus is a fully instrumented bench top Vortex Tube Refrigerator Apparatus having no moving parts and requiring only a compressed air or other suitable gas supply to operate.
The hermetically sealed refrigerant compressor incorporates a brushless three phase DC electric motor that is driven by a variable speed controller. Compressor speed and power supplied is displayed on the PC.
The condenser and evaporator are brazed plate heat exchanger and utilize a large common reservoir of water to minimize changes in water temperature during operation. The refrigerant exiting the compressor passes through a condenser, receiver, filter, variable area flow meter, expansion valve and evaporator before retuning to the inlet side of the compressor.

The Fridge Tag 2E, with internal sensor, is an electronic 30-Day Temperature Recorder (30DTR) with factory-programmed alarms and visual display for monitoring storage conditions in vaccine refrigerators (+2°C to +8°C) over a 30-day period. The Fridge Tag 2E has a USB interface and can be connected to a PC or Mac without any installation software. When connected, the Fridge Tag 2E will automatically generate a 60-day report in PDF and ASCII file formats, which includes all relevant information per day such as min/max and average temperatures, time out of range, alarm history etc. The device shows the actual temperature, all alarm violations over the previous 30 days (on a rolling basis), the daily minimum and maximum temperature of the last 30 days, and the time duration of any violation.

The solar energy is captured by a cylindrical parabolic solar concentrator in which the parabola axis is constituted by a high thermal conductivity tube and black colour containing an adequate liquid able to capture the solar energy increasing its temperature. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle is one of the most interesting applications of solar thermal energy because it is able to use the solar energy and, via an absorption cycle, to convert the energy in a source of cold that can be used for food conservation chain, air conditioning, chilling water and in general in all the applications of refrigeration and conditioning purposes without the use of electrical energy. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle has been designed and manufactured by Italia to allow the experimental study of an absorption refrigeration plant using solar energy as energy source. Owing the peculiarity of the plant able to use the solar energy to convert it in a source of cold, the plant is particularly interesting in all the countries of the equatorial area, where the sun is the main energy source and the coverage of the electrical network is scarce.
