Introduction
In many industrial processes such as air conditioning or power generation a cooling tower is used to
reject heat from the system. A reservoir may be used in these, or other processes to provide either a hot
or cold store for an industrial process that has varying load.
To investigate these processes the Hilton Air and Water Heat Pump R832 may be linked to the Hilton
Bench Top Cooling Tower H892 using the Hilton Reservoir System H060.
The Reservoir System H060 has a heat load and instrumentation, pumps, tanks, thermocouples and
flow measurement to allow both batch and flow heating and cooling processes to be investigated
The units carrying out heating and cooling processes (R832 or H892) may all be used to their full
specification either attached to the Reservoir System H060 or in their standard configuration in
isolation. This gives complete flexibility and maximum equipment utilisation.
The unit will be of particular interest to those studying:
• Refrigeration and Air Conditioning
• Building Services
• Chemical Engineering
• Energy Transfer and Conservation
• Mechanical Engineering
• Plant and Process Engineering

Description
The Laboratory Cooling Plant With Ice Store H060 has been designed to allow investigation of
both batch and flow heating and cooling processes.
The Reservoir System H060 comprises two insulated tanks mounted on a base with a central control
panel and dry cooling heat exchanger. Three high capacity circulating pumps and the necessary hoses
allow connection to three alternative Hilton units.
Utilising the Hilton Air and Water Heat Pump R832 the water evaporator is selected and this is
connected through hoses supplied to a coiled heat exchanger inside the Cold Reservoir. One of the
H060 circulating pumps provides a flow of water/glycol through the evaporator and heat exchanger
thereby cooling the water inside the Cold Reservoir. With suitable flow rate the water inside the Cold
Reservoir will form an ice bank around the heat exchanger. The Cold Reservoir is fitted with a heater
that may be controlled and its heat input measured using the wattmeter on the control panel.
The Hot Reservoir provides a source of water circulated by a second pump through the condenser of the
Air and Water Heat Pump R832 this raises the temperature of the water in the Hot Reservoir.
A third pump circulates the water in the Hot Reservoir through the Dry cooling Heat Exchanger.
All of the pumps and heat load may be operated from the Control Panel and the flow rates varied using
the original flow meters on the R832 unit.The flow through the Dry Cooling Heat Exchanger is
controlled and measured by the flow meter on the H060 unit.
With the addition of the Bench Top Cooling Tower H892 self sealing couplings allow the H892 to
replace the role of the Dry Cooling Heat Exchanger. As the H892 unit carries out evaporative cooling
the water can be cooled closer to the ambient wet bulb temperature and the performance relative to the
Dry Cooling Heat Exchanger may be investigated under identical load conditions.
The Control Panel includes a digital temperature indicator and selector switch to allow indication of all
relevant system temperatures.
Each of the Hilton units coupled to the Reservoir System H060 may be disconnecetd and operated in
isolation according to their full normal specification. This gives complete system flexibility and
maximises equipment utilisation.
The addition of the Reservoir System H060 to the Air and Water Heat Pump R832 and Bench Top
Cooling Tower H892 means that the requirement for a water supply and drain is removed and only a
power supply is necessary for operation of all three units.
