The Armfield HT10XC is a service unit, which can be used in conjunction with a range of small scale accessories for a wide range of demonstrations into the modes of heat transfer. The factors that affect heat transfer can be investigated and some of the practical problems associated with the transfer of heat can be clearly demonstrated. The heat transfer accessories may be individually connected to the HT10XC service unit, which provides the necessary electrical supplies and measurement facilities for investigation and comparison of the different heat transfer characteristics. A specific feature of the HT10XC is that it incorporates the facilities and safety features to allow the accessories to be remotely controlled from an external computer, where this is appropriate. With suitable (user provided) software, this means that the equipment can be operated remotely, for instance over an intra-net or even over the internet. All the facilities can also be accessed locally using the front panel controls and display. A bench top service unit designed to interface to a range of heat transfer accessories. • Provides a variable, stabilised 0-24V DC supply to the heater of the heat transfer accessory, with a current capability of 9A. • Provides a drive signal for a proportioning solenoid valve used for flow control. • Provides a control signal to a variable speed blower used for generating airflow. • 10 temperature inputs and conditioning circuits for K-type thermocouples: • Instrumentation inputs for heater voltage, heater current, air flow, water flow, radiation and light meter. • Integral USB interface, and educational software for all accessories. • Outputs can be controlled manually from the front panel, or controlled by the software from a user supplied PC. • Watchdog circuit for operator and equipment safety in case of computer or interface failure when being controlled remotely(e.g. over a network or the internet using user written software). • Easy interfacing to 3rd party software e.g.LabView, MatLab. • A comprehensive instruction manual describing how to carry out the laboratory teaching exercises in non-steady state heat transfer and their analysis as well as assembly, installation and commissioning is included. |
Based on a Peltier device, the Armfield HT18C Thermo-electric Heat Pump demonstrates how electrical power can be used to extract heat from a cool surface and transfer it to a hot surface. This effect is becoming widely used for point cooling (e.g. of semiconductor devices) and small scale volumetric cooling. The HT18C is designed for use with the Armfield HT10XC Heat Transfer Teaching Equipment. > Performance of a Peltier device as a cooler > Heat transfer characteristics as a function of temperature and drive current > Measurement of the co-efficient of performance > Energy balance > Demonstration of a Peltier device as an electrical generator All electrical requirements are obtained from the HT10XC service unit NOTE: the supply rating of the HT18C must be the same as the HT10XC that it is used with, i.e. HT18C-A: 230V/1ph/50Hz |

A range of small scale heat exchangers, designed to illustrate the principles and techniques of indirect heat transfer between fluid streams. Different types of heat exchanger can be mounted on a common bench-top service unit. Small scale versions of commonly used industrial heat exchangers are available (including plate, tubular and ‘shell and tube’) for analysis and comparison. The equipment is controlled by a user supplied personal computer, which serves as the operator interface. Full data logging, control and educational software is supplied with the equipment. In addition, the equipment has been fitted with failsafe systems, including a watchdog circuit, which allows for safe operation from a remote computer. Small scale, bench top equipment > Fast response times allow in depth investigations in a short time > Representative of industrial heat exchangers > Multiple, industrially representative heat exchangers available > All functions computer controlled, including reversing of one of the fluid streams for co-current and counter-current investigations > Standard USB interface > Safety functions implemented to allow for remote operation by computer > Full educational software with data logging, control, graph plotting, and detailed ‘Help’ > Suitable for project work. The service bench provides facilities for evaluating in-house heat exchanger designs The user must have access to a PC with a free USB port, running Windows 98, or later. At least one heat exchanger module is required, additional heat exchangers are optional. |
