Recycle Loops

Product Code: LBNY-0005-11200087 - (Recycle Loops)

The apparatus consists of a through pipe conveying water from a cold water supply to a suitable drain with a loop of pipework connected between the supply and drain connections. The heater can be switched on or off to generate step changes when investigating the transient responses of the recycle loop. This recycle loop incorporates a circulating pump and a heater to raise the temperature of the water in the loop. 
A bench top unit designed to introduce students to the characteristics of a recycle loop and the typical responses under steady state and unsteady state conditions.
The arrangement also permits different lengths of flexible tubing to be connected in series with the loop if it is required to create further changes in residence time. A pair of self-sealing fittings enables a short length of pipe or a reservoir to be connected in series with the recyle loop to change the volume of the loop and demonstrate the effect of residence time.

Refrigeration Chamber and Defrosting Methods

Product Code: LBNY-0005-11700041 - (Refrigeration Chamber and Defrosting Methods)

This climate depends on different influences, such as the surface temperature of the evaporators, cold storage room temperature, degree of evaporator icing, quantity and type of refrigerated goods etc. Icing of the evaporators significantly reduces the refrigeration capacity and must therefore be prevented as much as possible by periodic defrosting, i.e. heating the evaporator surfaces. The climate in the cold storage room has a significant effect on the quality of the products stored there. The icing of the evaporators depends on the evaporator and room temperatures and the quantity of humidity introduced by the refrigerated goods. The evaporator surface can be heated from the outside by electric heating or from the inside by hot gas directly from the refrigerant compressor. In addition to the periodic defrosting at set times, there is defrosting performed as required by measuring the actual ice coating.
