R832 Air and Water Heat Pump
A bench top air and water heat pump with a water cooled hermetic compressor, water cooled condenser, air source evaporator and water source evaporator using a compact plate heat exchanger. Fully instrumented with all system pressures, temperatures, water and refrigerant flow rates and compressor power input. The unit allows a complete refrigeration cycle pressure-enthalpy diagram to be created as well as heat pump performance curves over a range of condensing and evaporating temperatures.

An optional computerised data acquisition system is available that may be supplied factory fitted or installed as a user upgrade. The Windows software is menu driven and allows data files to be exported to Excel or other spread sheet formats for evaluation and presentation.

	R852 Vapour Jet Refrigerator/Heat Pump A bench top example of a refrigerator/heat pump that is driven by a heat source. The unit operates on a combined Rankine and vapour compression refrigeration cycle using a low pressure, non-toxic ozone friendly refrigerant. A simple ejector (or thermo-compressor) performs the expansion and compression processes involved in the combined cycles. A small electric motor drives the pump of the Rankine cycle. The heat source is electrically heated and produces high pressure vapour to drive the ejector. Supplied in standard form with an electric heat source, an optional set of Solar Panels and Installation Package (F820S) is available to demonstrate the generation of a refrigerating effect directly from solar radiation.

CBT Computer Based Refrigeration Training
A comprehensive introduction to the vapour compression refrigeration cycle, its history of development, application, analysis and performance.

The software allows individuals to progress at their own pace and enables students to acquire knowledge of the refrigeration cycle before undertaking laboratory experimentation. The content introduces cycle analysis, explains the refrigerant pressure-enthalpy diagram, tabulated refrigerant data and how these may be used to analyse data from a typical refrigeration system. The software also introduces students to industrial refrigeration practice and typical components.

CONVERSION UPGRADES

In accordance with the Montreal Protocol all current Hilton refrigeration equipment operates on non-ozone depleting substances and complies with the latest international standards. In line with our philosophy of providing an effective and continuing after sales service to existing customers we are pleased to offer a complete range of conversion upgrades to enable all of our earlier units to operate on the new refrigerants.

The upgrades are supplied with comprehen- sive fitting instructions to enable the con- version to be undertaken by a competent refrigeration engineer/technician.

If required, the conversion work may be undertaken at our factory at an additional cost.
