AYVA offers teaching equipment for refrigeration covering the fundamental theories associated with thermodynamics, fluid mechanics and heat transfer – enabling students to understand HVAC environmental control in the real industrial and consumer world!
Environmental Control Teaching Equipment
The air conditioning and refrigeration (HVAC and R) industry designs, builds, maintains and repairs essential indoor comfort and cooling systems including heating, ventilation and air conditioning. The expanding markets for refrigeration and air conditioning and changing technology, has created a growing need for training.
Our partner in England, TecQuipment (TQ) offers refrigeration training solutions and experiments that allow students to comprehend the workings of cooling towers, refrigeration and air conditioning; utilizing psychrometric and P-h charts.
The unit features an air-cooled condenser unit connected to an evaporator located in an air duct. The air duct contains relative humidity and temperature sensors on both sides of the evaporator. A small fan provides air flow down the duct and can be manually adjusted.
The refrigeration circuit features high and low pressure gauges, a pressure switch, sight glass, filter dryer and TEV valve. The circuit also includes pressure transducers that connect to the instrumentation.
Four thermocouples placed around the refrigeration circuit allow observation of temperatures, these can be used for the calculation of potential super heating and sub-cooling.
Our partner in France, ERIDÈS offers a unique solution with transparent walls which lets student watch the visible condensation and evaporation allowing for the understanding of the cycle processes.
This refrigeration cycle training unit allows for measurement of flow rate, pressure, temperature and more.
The fluid enthalpy chart is transposed onto a transparency at the centre of the unit allowing for rapid analysis of the fluid state parameters at any given point.
Transparent walls allow visibility on all sides while protecting both the equipment and its users. The visible condensation and evaporation allows for the understanding of the cycle processes. Once the machine has reached steady state, measurements can be taken and can be used even after the machine has been turned off.

The University of Bradford in West Yorkshire raises the bar on practical learning of engineering science with TecQuipment products.
Engineering Laboratory Equipment: Engineering science, structures, materials and theory of machines
Bradford University Faculty of Engineering and Informatics has a number of different learning spaces to support a variety of engineering courses, including a multi-disciplinary engineering laboratory (360 degree view of the lab available here). This is an open plan laboratory, which offers a practical learning environment and efficient use of space, which incorporates a wide range of TecQuipment’s bench-mounted equipment, including a broad range of structures and materials testing equipment, such as the Thick Cylinder Apparatus.
The department also has an extensive range of Engineering Science units. These provide the perfect introduction to the fundamental principles in mechanical engineering and are often used in combination with more complex varieties of the experiments (such as the ES Gears Train Kit and the Geared Systems).
Check out the video made during a little down time at Bradford University for the Thick Cylinder Apparatus from our Materials Testing range:
During a recent visit to TecQuipment’s (TQ) we were very excited to see that they have recently expanded their offering of flow channels.
TQ’s flow channels are large open channel flumes that provide the opportunity for advanced research and student study on a wide range of fluid flow topics.
TQ’s flumes and flow channels are available in various models (from a space-efficient 2.5 meters to a research caliber size of 15 meters.), giving students have a wide choice of experimentation in open channel flow.
The flumes are made of transparent glass, precision-built to ensure parallel walls and a consistently accurate cross-section along its length. A sturdy steel square-section firmly supports the channel throughout its length. It has a floor-standing frame that supports the working section at a convenient eye-level position for students.
The FC80 and FC300 models have a built-in re-circulating water supply connected to a digital flow meter for accurate measurements during experimentation.
The FC50 is designed primarily for use with TQ’s Digital Hydraulic Bench which provides the necessary water supply, drain and digital flow-measurement facilities.
If you would like to visit TecQuipment in Nottingham, England to see these flow channels and flumes in action just give us a call and we would be pleased to arrange a visit/demonstration.<
"I’m often running two lab sessions at one time in two different rooms. Being able to use the base module like TecQuipment's Hydraulic Bench and quickly be able to switch out the experimental modules makes running a tight schedule of laboratory sessions possible. With a few of my own modifications like adding quick connects and valves I can make this changeover even slicker. The AVYA experience is great! Their post-sale technical support is unparalleled."
Dean Milton, University of Regina
"Out of all the data acquisition systems I'm aware of, nothing approaches the convenience of the PASCO 850 interface. Between the broad range of available sensors and the simplicity of starting data acquisition, a wide range of tasks that would be incredibly complicated otherwise can be automated in minutes ... We have dedicated computers and 850 interfaces at each station in our labs so that data acquisition can be accomplished easily by our students whenever needed."
Gideon Humphrey University of Toronto
"In recent years, there has been a growing demand for engineering equipment in the undergraduate labs at the University of Guelph as we have expanded our program. AYVA has been proactive and assisted us diligently in addressing all our equipment needs. We now proudly showcase both PASCO and TecQuipment products in our teaching labs. The quality of the equipment and teaching material is exceptional. AYVA offers a broad range of equipment well suited to our various engineering disciplines and we look forward to exploring their extended product offering in the future."

"Our mechanical engineering department recently wanted to upgrade our Gas Dynamics Laboratory in conjunction with our newly added aerospace program. After extensive research, we decided to purchase the AF27 Nozzle Flow Apparatus and the AF300 Intermittent Supersonic Wind Tunnel from TecQuipment with all the accessories including the VDAS Data Acquisition System. We are happy to report our investment has been well worth it. A perfect fit for our undergraduate laboratory. Students are raving how “cool” the units are and the relative ease to obtain accurate data. The laboratory size supersonic wind tunnel has been a big hit. At Mach 1.8, viewing the shock waves and expansion fans on an airfoil using the included Schlieren Apparatus has never been easier and more clear. The people at AYVA were amazing in helping us install the equipment. They answered all our question in a timely manner and delivered on time. The equipment is very well designed and built to last for a long time."

"All of the students that have the opportunity to see the [Eridès] Refrigeration Trainer in operation and do their lab report based on readings really get a lot out of it. Interesting to note: Our refrigeration tech was fascinated by the unit. He is a very experienced technician, and he was simply amazed at seeing the thermodynamic cycle in action. Typically, refrigeration technicians follow pressure and temperature readings, and gauging from his reaction, they most times give little thought to the phase changes that take place inside the guts of the unit.'
