The installation includes: evaporator; chamber with condenser; additional condenser; cooling thermostat, vacuum pump.
Testing facility for heat exchangers Water-Air
The unit is designed for testing and controlling the characteristics of heat exchangers with gas-liquid processing medium.
Installation setup includes:
Heat pump installations with refrigerant and carbon dioxide
A number of heat engineering tests were conducted at the experimental stands to assess the energy efficiency of Heat Pumps. Purpose: the use of mixed refrigerants and the prototype installation on carbon dioxide for the study of heat and mass transfer in power equipment.
Application of Heat Pumps allows to reduce the coefficient of primary fuel use, to reduce heat losses in heat networks, to create dual-purpose cooling and heat supply systems, in which the exergy efficiency is significantly higher in comparison with single-purpose systems.
Experimental installation for the study of thermal stabilizers up to 2.5 m in length for power and transport infrastructure facilities.
The installation consists of two parts: a container with model soil and a thermal stabilizer with measuring equipment and a refrigeration unit.
The tank is designed to observe a cylindrical temperature field around the thermal stabilizer. The model soil can be translucent for optical observation of the movement of the freezing boundary.
Models can consist of ground glass particles, micro- and nanoparticles, aluminum oxide, silicon oxide and water.
The thermal stabilizer is collapsible, which allows to explore various working fluids and coatings.

- Project “The influence of ambient conditions on proton-exchange fuel cell performance”
Goal: to determine the influence of multiple parameters on PEM fuel cell performance.

- Project “H2Bio hybrid energy storage integration into the system, experimental investigation of the fuel cell working modes, hydrogen sorption/desorption processes, system performance”
Equipment: H2Bio – hybrid energy storage equipment based on PEM fuel cell and metal hydride accumulator
Goal: experimental and theoretical investigation of a hybrid energy system, including a proton exchange membrane (PEM) fuel cell (FC), metal hydride (MH) accumulator and an electro-chemical battery.
Results: the fuel cell, the battery, and the load joint functioning was investigated in the experiments, measuring thermal and electrical parameters of the setup. Following quantities were measured:
Current on the load was changed throughout the experiment, power of the load has been calculated. Power of the fuel cell was measured in order to see whether it meets the load demand or not, it also helped to investigate the fuel cell shut downs. All measurements were taken by NI-PXI where physical measurements were transformed to the analogous signals. The process of measurements’ representation has been automated using LabView, and instantaneous values were logged into a file for further processing.
It was noted that 4 working modes of the fuel cell repeat one after another. These working modes represented the start of the system, an optimal performance stage and some of the most common fuel cell shut downs.

The experimental setup is a two-machine setup shown in Fig.1. It allows carrying out basic and advanced tests on the electric machines. It consists of a standard duty DC motor, rated at about 1 horsepower (746 watts), with a 240 volt armature and field winding rating, and a ‘slip ring’ motor of about the same rating. The setup includes a torque meter and a tachometer. The system has three DC power supplies for the basic experiments, plus a smaller supply to provide excitation voltage for the tachometer.
The setup is used in experimental part of the course “Electric Machines”. It allows testing DC motor and generation modes, AC synchronous motor and generator, AC induction motor. Some of the tests performed are the following.

Team leader: Dr. Petr Vorobev (MIT)
Team members: Vasily Chirkin
Goal: The results of the experiments are meant to prove the novel modelling and control methods devoted to extend the stability limits of such systems.
Task: The setup will allow studying the voltage collapse phenomena causing system disruption in power grid with high penetration of induction motor load.
A multi-machine experimental setup is being developed in the framework of the Grant Agreement No.14.615.21.0001 dated 09.09.2014 between the Ministry of Education and Science of the Russian Federation on the topic: “Dynamics stability and control of distribution girds“. The effect of voltage instability and fault-induced delayed voltage recovery resulting in voltage collapse resulting problem in many partial or complete system blackouts is studied.
The setup will represent the distributed network with 3 three-phase induction motors and 3 single-phase induction motors running at constant torque (modelling of compressor application in air conditioning systems). The network is supplied by three-phase AC synchronous generator with variable active and reactive power outcome (output voltage can be maintained 0,5-1,1 pu). The switch models a fault-induced delayed voltage recovery (50-150 ms). The motors’ voltages, currents and speed is observed by means of high-speed data acquisition device (DAQ).
