Heat exchangers are an elementary part of refrigeration systems. During cooling they are used to absorb the energy of the refrigerant by evaporation. During heating they discharge the energy set free during the condensation of the refrigerant. They are also used for internal energy transfer during superheating or supercooling of the refrigerant. Dependent on the media, a difference is made between air/refrigerant, water/refrigerant and refrigerant/refrigerant heat exchangers. Dependent on the constructive design, a difference is also made between coaxial, finned tube, plate or shell & tube heat exchangers. The refrigeration circuit of the trainer includes as evaporator an air cooling finned tube heat exchanger and a water-heated plate heat exchanger, as superheater a tubular heat exchanger, and as condenser a water-cooled coaxial coil heat exchanger. These heat exchangers are the ones used most commonly in refrigeration and fulfil different functions dependent on the system type. A finned tube heat exchanger can e.g. also be used as a condenser. By measuring the mass flow rates and the inlet and outlet temperatures the transferred energy fluxes can be determined. The components are arranged clearly at the front. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. - different heat exchangers and their use in refrigeration * coaxial coil heat exchanger * finned tube heat exchanger * tubular heat exchanger * plate heat exchanger - find out the correct installation position - determine energy fluxes - effect of superheating and supercooling of the refrigerant on the cyclic process - design of a compression refrigeration system - representation of the cyclic process in the log p-h diagram....

modular system allows experiments on the generation, storage and use of heat from renewable energies. is one module in this system and includes a heat pump that can be connected to different heat sources and consumers. The heat pump comprises a compressor, a condenser, an expansion valve and an evaporator. These components are connected to each other via a refrigeration circuit. The refrigerant circulates in the refrigeration circuit powered by the compressor. A source's thermal energy is absorbed at the evaporator. Additional energy is added to the evaporated refrigerant in the compressor. This energy can be output to a consumer as heat. On the trainer, the condenser can be incorporated into a heating circuit consisting of various consumers. The evaporator can be connected to a brine circuit with different heat sources. The pipes with quick quick-release couplings, circulation pumps and accessories necessary to create these connections are provided. In practice and depending on the application, different system configurations are often required for optimal efficiency of a heating system. Using and other modules it is possible to systematically investigate the possible variants for incorporating a heat pump into a modern heating system. Carefully structured instructional materials have been created for the recommended module combinations with the module. As part of the documentation for the overall system, these materials set out the basic principles and provide a step-by-step guide through the experiments. Familiarisation with heat pump applications for heating rooms and hot water - Using the heat pump for cooling - Advantages and disadvantages of various system configurations (brine heat pump, air heat pump) - Configuring and adjusting a heat pump controller - Operating behaviour under varying heat supply and demand - Dependence of the coefficient of performance on source and sink temperature - Possibilities for optimising the seasonal performance factor....
Manufacturers and suppliers of Heat Pump for Cooling and Heating Operation for engineering labs worldwide.
Refrigeration systems and heat pumps only differ in the definition of their use, but can be of the same design. For example, goods can be refrigerated in a supermarket and the store heated with the waste heat. The store can also be cooled with the same system in the summer. With ET 405 the cooling and heating operation can be investigated. Different operating modes can be selected via solenoid valves. The refrigeration circuit with compressor and condenser (heat exchanger with fan) includes two evaporators with fans (refrigeration stage and freezing stage) and thermostatic expansion valves. The two evaporators can be connected in parallel or in series. For the connection in series the capillary tube serves as expansion element for the refrigeration stage evaporator. The refrigerant circuit is connected to a glycol-water circuit via a coaxial coil heat exchanger. Via solenoid valves the coaxial coil heat exchanger can be switched as an evaporator or condenser. Thus the glycol-water mixture in the tank can be heated or cooled. In pure cooling operation (without heating function) the heat exchanger with fan as air-cooled condenser dissipates the heat. This heat exchanger can be also switched as an evaporator. The measured values are read from digital displays and can at the same time be transmitted via USB directly to a PC where they can be analysed using the software included. The software enables a clear representation of the process. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. - design, operation and key components of a heat pump or refrigeration system - representation of the thermodynamic cycle in the log p-h diagram - comparing different operating modes - measurement of compressor capacity and heating or cooling capacity in the glycol-water circuit - determination of * efficiency * coefficient of performance of heat pump and refrigeration system * specific compressor load * compressor pressure ratio * specific cooling capacity * specific refrigeration capacity - comparing key figures of heat pump and refrigeration system....

With the air-to-water heat pump ET 102 the ambient heat of the air is used to heat water. The heat pump circuit consists of a compressor, an evaporator with fan, a thermostatic expansion valve and a coaxial coil heat exchanger as condenser. All components are clearly arranged in the trainer. The compressed refrigerant steam condenses in the outer pipe of the condenser and thereby discharges heat to the water in the inner pipe. The liquid refrigerant evaporates at low pressure in the finned tube evaporator and thereby absorbs heat from the ambient air. The hot water circuit consists of a tank, a pump and the condenser as heater. For a continuous operation the generated heat is dissipated via an external cooling water connection. The cooling water flow rate is set via a valve and measured. All relevant measured values are recorded by sensors. Displays at the respective locations of measurement indicate the measured values. This makes it easy to assign the measured values to the process. The simultaneous transmission of the measurements to a data recording software enables analysis and the representation of the process in the log p-h diagram. The software also displays the key characteristics variables of the process, such as the compressor pressure ratio and the coefficient of performance. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments. design and operation of an air-to-water heat pump - representation of the thermodynamic cycle in the log p-h diagram - energy balances - determination of important characteristic variables * compressor pressure ratio * ideal coefficient of performance * real coefficient of performance - dependence of the real coefficient of performance on the temperature difference (air-to-water) - operating behaviour under load....

The aim of this basic experiment is to determine the heat transfer coefficients, a specific indicator, from the cooling curve. Cooling curves describe the temperature compensation between a body and its surroundings, as a function of time. Used in conjunction with the accessory makes it possible to record the cooling curve of a cylinder in air flow. The accessory includes an oven and a copper cylinder. The large copper cylinder is heated in the oven to approximately 120°C. Then, the heated cylinder is placed in s intake pipe and cooled in an air flow. A temperature sensor is fitted inside the cylinder. The convective heat transfer on the cylinder can be determined from the cooling rate. The experiment can be performed for various flow rates. The measured values are analysed using the software. is part of a series that allows experiments on the principles of incompressible air flow.
