Computerized Bench Top Cold Storage Trainer
Product Code : EL-RAACLE-10788
Quick Answer:
The Computerized Bench Top Cold Storage Trainer features a large refrigeration chamber with two evaporators for investigating the effect of different evaporator sizes on the cold storage room climate and icing, plus an electric defrost heater and hot gas defrosting that can be run via a defrost controller as required or at set intervals via a defrost timer. Two adjustable heat sources in the chamber simulate the cooling load, one of which generates water steam to simulate introducing humidity into the chamber. Measured values are shown on digital displays and, via the included data acquisition software, transmitted directly to a PC over USB -- enabling recording of the defrosting process over time and online representation of the chamber climate in the h-x diagram, with the refrigerant flow rate determined by means of the pressure measurement.
Overview:
The trainer features a large refrigeration chamber with two evaporators, allowing an investigation of the effect of different evaporator sizes on the cold storage room climate and the icing. An electric defrost heater and hot gas defrosting are available, and the defrost process can be performed as required using a defrost controller or at set intervals using a defrost timer. Two adjustable heat sources in the refrigeration chamber simulate the cooling load, and one of these heat sources generates water steam to simulate the introduction of humidity into the refrigeration chamber.
The measured values can be read on digital displays, and at the same time can also be transmitted directly to a PC via USB using the included data acquisition software. The data acquisition enables, for example, the recording of the defrosting process over time and the online representation of the climate in the refrigeration chamber in the h-x diagram, and the flow rate of the refrigerant is determined by means of the pressure measurement.
