Renewable Energy Research Institute

Equipment

• Pilot plant of indoor solar collectors test.

Pilot plant of indoor solar collector test

Since the end of 2011, ethe research group has a test bench for solar collectors inside in its facilities. In this bench the intensity of radiation can be regulated by a solar radiation simulation system, allowing a control better of the different variables that affect the collector operation. The bank also has a flow and temperature control system The purchase of this equipment has been financed by the Vice-Rector for Research of the University of Castilla-La Mancha.

• Prototype of a thermal energy storage system in a fluidized bed.

Prototype of a thermal energy storage system in a fluidized bed

The research group has a prototype of this new thermal energy storage system, where they study the feasibility of using this technology as a storage system. The equipment has control of the flow and the air temperature as well as measurement of the different losses of load in the circuit and temperatures in different points of the facility.

• Rheometer MCR-302

Rheometer: MCR-302

Among the recent laboratory equipment, it is worth mentioning Compact Modular Rheometer, MCR-302 model (Anton Paar GmbH®). This device incorporates a patented technology of motor "electronically commutated motor", supported in pressurized air bearings and with normal force sensor. Two air bearings support the motor, a radial bearing centers and stabilizes the shaft and the axial air bearing supports the weight of the rotating parts. In this way, measurements can be made at low torque up to a minimum of 2nNm and a maximum of 200mNm. It also has a TruGAP® system for automatic hole control and T-Ready® function for temperature control of the sample and speed. It is a rotational viscometer, which includes a cylinder as a measuring element that is inserted into a container or cup where the product is placed, which allows the measurement of liquids at low viscosity, as well as viscoelastic liquids. The equipment has a Peltier modular temperature device type C-PTD200 linked to a thermostatic bath, which allows controlling the temperature of the analyzed product within a range between -30ºC and 200ºC. In addition, the group also has the kit "Fluidization Scientific" that allows to quantify the rheology of particles in fluidization conditions.

• T-History

T-History

Recent acquisition of the laboratory; this device is available since December-2017.

It can obtain, through T-History methodology, the enthalpy-temperature curve ofor different materials such as: Phase change Material.

• System to determine the effective thermal conductivity in granular materials

System to determine the effective thermal conductivity in granular materials

These systems allow to determine the effective average conductivity in a bed of solid particles. Unlike traditional systems for the determination of thermal conductivity in pure materials, this system allows to obtain the effective conductivity in a no-homogeneous medium, such as a packed bed of particles. The system allows determining the effective conductivity with different fluids circulating in the bed and in different directions (axial or radial) as well as quantifying the influence of natural convection in the system. The system has been developed and designed by the research group.

• Pilot plant of characterization and heat exchanger test

Pilot plant of characterisation and of heat exchangers test

One of the novel facilities available in the laboratory is the industrial pilot plant for the characterization and testing of tubular heat exchangers. This installation allows to work with different types of exchangers: double and triple tube and multitube and in a temperature range between 0 and 100 ºC. The plant has three loops, one of heating, with a secondary circuit concentrated to a 72 kW electric boiler, one cooling, connected to a 40 kW chiller and a third loop with mains water. It has two storage tanks of 600 L and different types of pumps, which allow working with non-Newtonian fluids and with high viscosities

• Data acquisition systems

Data acquisition system

Currently, the research group has different equipment that allows the monitoring, measurement and / or control of any installation. Specifically we have:

Data acquisition system based on NI systems.
Portable pyranometer with data storage.
Portable Dataloggers to measure temperatures.

• Solar cooker

Solar Cookers

Solar cookers are a technology in development as a clean and economical way of cooking. Its use is spreading in developing countries. Within the research group, modeling and experimentation studies have been carried out with box-type solar cookers

• Specialized software

The research group works with different specialized software.
