Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Oil Return in Refrigeration Systems
The unit addresses the problem of oil return in refrigerant circuits. In refrigerant circuits the lubricant is carried through the pipe system by the refrigerant. Oil may impact the compressor if the system is overfilled. If the system is underfilled the compressor may run dry. The selection of the correct diameter and arrangement of pipework is therefore of key importance. The effect of the refrigerant flow rate on the oil return to the compressor is demonstrated on this unit with the aid of glass intake pipes. A complete refrigerant circuit is mounted on the rear of the demonstration panel. To demonstrate the effect of different pipe diameters and routing, individual sections can be selected using ball valves. Pressures and flow rates are measured in the refrigerant circuit. The laboratory trolley mounted system is flexible and suitable for use in different seminar or training rooms.
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Gas Heated Absorption Refrigeration Unit
Unlike mechanically driven compression refrigeration systems, absorption systems use thermal energy directly. There are three circuits in the system: a water circuit, an ammonia circuit and a hydrogen circuit. The system comprises a generator, a condenser, an evaporator with a downstream gas heat exchanger, an absorber and a liquid heat exchanger. The generator is heated with gas not electricity. The unit can therefore be operated independent of the mains electricity.
A supply of propane gas is necessary for operation.
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Reverse Cycle Refrigeration Training System
The contains a hermetic compressor, 4 heat exchangers, 3 expansion valves and 4 different interchangeable capillaries. The unit can be operated in different modes. 11 manually operated valves allow corresponding changes to be made to the refrigeration circuit. The relevant measured values are displayed directly on indicator instruments. Therefore, sequences and consequences of switching operations within a cooling unit can be directly investigated. Sight glasses in the refrigerant circuit allow direct observation of the refrigerant status. A coaxial tube bundle heat exchanger can be operated as a counterflow condenser or as a parallel flow evaporator. This heat exchanger is used to heat or cool a glycol/water mixture circuit. Refrigerating loads are created by different fan speeds on the finned tube evaporators.
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Capacity Control Methods in Refrigeration
This unit demonstrates several possible ways of regulating the capacity. The cooling capacity of the system with 2 separate evaporators can be changed by adjusting the speed of the open compressor. The compressor drive motor is controlled using a frequency converter. The evaporators are in individual insulated compartments. In the first compartment the temperature is regulated using an intake pressure controller and thermostat (mechanical regulation), in the second compartment using a case controller (electronic regulation). In both cooling compartments a cooling load can be generated using an electrical heater. Fans ensure even temperature distribution. A bypass capacity regulator is installed in the refrigerant circuit that connects the high and low pressure sides of the compressor. The system is equipped with temperature sensors at all relevant measuring points. The signals provided by these sensors are also used by the case controller.
Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of Single Chamber Refrigerator Module.
The experimental set-up is clearly arranged on a metal board which is placed on the base unit. The pipe connection between base unit and auxiliary module is made via self-locking Schrader valves. The individual components of the unit, in this case temperature control, fans, heater, compressor and solenoid valves, are controlled by the software (included in the scope of supply of the base unit). The refrigerating capacity is generated by an evaporator in an enclosed chamber. A blower is used to help achieve the even distribution of temperatures in the chamber. In addition, a heater can be used to simulate a cooling load. Solenoid valves permit the operation of the unit with a capillary tube or with an expansion valve as the expansion element.

Hermetic refrigerant compressors like, e.g., the have a welded sheet steel housing. The drive motor and refrigerant compressor are fitted in this capsule. Unlike open compressors, the refrigerant compressor is directly connected to the drive motor and therefore does not require any floating seal. The motor compressor is suspended by springs in the capsular housing which minimises the transmission of vibration to the capsule body, thereby reducing noise emission.
