Products

• TCRB: Refrigeration Cycle Demonstration Unit — EDIBON: Vapour compression refrigeration and heat pump cycle with the evaporation and condensation processes visible inside glass cylinders. Water flows through nickel plated coils in each vessel, and control valves let students vary the evaporating and condensing pressures.
• TRCVC: Computer Controlled Vapour-Compression Refrigeration Unit — EDIBON: Water cooled vapour compression plant instrumented at every stage of the cycle. Two computer controlled pumps feed the condenser and evaporator from a reservoir, so students can change operating conditions and watch how the system responds.
• TSCR: Simple Compression Refrigeration Circuit Unit — EDIBON: Basic compression refrigeration system in which the evaporator and condenser are copper coils immersed in water filled tanks that stand in for the surroundings. It suits introductory work on the vapour compression cycle and simple energy balances.
• TSCC: Computer Controlled Two-Stage Compression Refrigeration Unit — EDIBON: Two stage compression plant for reaching low temperatures, with two hermetic compressors in series. Optional intermediate cooling by liquid injection and optional subcooling before expansion let students compare cycle variants on the p-h diagram.
• TRAB: Absorption Refrigeration Unit — EDIBON: Laboratory unit that demonstrates absorption refrigeration using an ammonia and water solution, with ammonia as refrigerant and water as absorbent. It can be driven by LPG or by electricity, so the effect of the heat source on the cycle can be compared.
• TCREV: Compression Refrigeration Unit with Different Expansion Valves — EDIBON: Fully operational refrigeration circuit fitted with three different expansion devices so their behaviour can be compared. A four way reversing valve switches the plant between refrigeration and heat pump operation.
• TCRCT: Refrigeration Unit with Different Capillary Tubes — EDIBON: Compression refrigeration system supplied with three capillary tubes of different length plus a thermostatic expansion valve, so expansion devices can be compared. An extra receiver allows the effects of overcharging and undercharging to be studied.
• TRCC: Computer Controlled Refrigeration Unit with Open Compressor — EDIBON: Compression refrigeration plant built around an open compressor driven by an electric motor through a V-belt. The motor speed is adjustable and the motor is pendulum mounted with a force sensor, so the cycle can be studied at different degrees of compression.
• TRRC: Computer Controlled Refrigeration Unit with Refrigeration and Freezing Chamber — EDIBON: Two chamber plant in which the circuit branches after the accumulator so a refrigeration chamber and a freezing chamber can run separately or together. An evaporation pressure regulator holds the refrigeration chamber at a higher pressure than the freezing chamber.
• TRD2PC: Computer Controlled Two Doors Domestic Refrigeration Unit — EDIBON: Combined fridge freezer with transparent panels so that the compressor, filter, evaporator and condenser of a domestic refrigeration cycle can be seen in place. Sensors along the circuit and inside both compartments support study of thermostat setting and food placement.
• TRCAC: Computer Controlled Refrigeration Circuit with Variable Load — EDIBON: Refrigeration cycle in which the evaporator takes its heat from a water circuit whose temperature is set from the computer. Varying that thermal load lets students see how the cycle adapts and how performance changes with load.
• TCFRC: Computer Controlled Capacity Control and Faults in Refrigeration Systems — EDIBON: Two chamber refrigeration plant for studying capacity regulation methods and for simulating typical faults such as defective valves or blocked pipes. Faults are activated from a touch screen and the cycle is plotted on the log p-h diagram.
• THALAC/1: Computer Controlled Refrigeration Control Unit with Several Compressors — EDIBON: Heat pump circuit with an air evaporator and a water condenser served by three compressors in parallel. Students compare the energy used by a single compressor with combined operation and follow the cyclic process on the p-h state diagram.
• TPVB: Vortex Tube Refrigerator Unit — EDIBON: Compressed air unit for studying the physical, mechanical and thermodynamic behaviour of a vortex tube. Air entering tangentially splits into a cold stream and a hot stream that leave at opposite ends, with no moving parts involved.
• TBTC: Computer Controlled Thermo-Electric Heat Pump — EDIBON: Peltier module mounted between a heated cold side and a finned heatsink, used to study thermoelectric phenomena. Students investigate the Peltier, Thomson and Seebeck effects and use the module as a heat pump and as a refrigeration device.
• TTEB: Bench Top Cooling Tower — EDIBON: Bench scale cooling tower with a closed water circuit and an open air circuit, reproducing evaporative cooling with direct air to water contact. Mass and energy balances and overall efficiency can be calculated from the temperature readings.
• TPCC: Computer Controlled Contact Plate Freezer — EDIBON: Compression refrigeration circuit whose evaporator is a contact plate freezer, used to freeze packaged food quickly by an industrial method. Several probes can be placed in the product so the freezing front can be followed through the process.
• TCPISC: Computer Controlled Cooling Plant with Ice Store — EDIBON: Refrigeration plant with an ice thermal store, used to study cold production during off peak hours and its use at times of high demand. Operating modes are selected with manual valves so different configurations can be compared.
• THER: Heat Exchangers in the Refrigeration Unit — EDIBON: Refrigeration circuit that gathers the exchangers most often used in refrigeration on one front panel. Students see how the same exchanger can act as evaporator or condenser and quantify the energy exchanged in each device.
• TAAB: Air Conditioning Laboratory Unit — EDIBON: Stainless steel test tunnel with an evaporator, heating elements and steam injection, used to demonstrate heating, cooling, humidification and dehumidification of air. The refrigeration circuit is instrumented so the cycle can be studied alongside the air processes.
