| Practices of laboratory |
PL 1. Introduction to thermal comfort and indoor air quality.
The aim of this practice is to determine the air humidity in different indoor stays of buildings and in the outside. Besides, the concept of thermal comfort and indoor air quality are introduced, features that are related with the health and the welfare of the users of buildings. Equipment of measurement employed: hygrometers, sensors of temperature, measurers of quality of indoor air, etc.
PL 2. Fuels and combustion. Boiler room of the students’ barracks building.
A technical visit will be made to the boiler room of the Francisco Moreno barracks, which consists of two natural gas boilers and provides domestic hot water (DHW) and heating to the student barracks. The purpose of the visit is to identify the equipment involved in a heating system and learn how to make a simplified scheme of the installation. In addition, this practice includes the study of health and safety conditions in a boiler room: identification of risks, emergency measures, PRL, Legionella control, etc.
PL 3. Development and presentation of works on social, health and security features related to Thermal Engineering.
In this practice the students have to present the work developed during the first weeks of course. The works are proposed by the lecturers at the beginning of the course and they will be made by groups of 4 or 5 students. The subjects will treat on social, health and industrial security of related to Thermal Engineering. For example: energy efficiency in buildings, energy efficiency in ships, storage and transport of liquid fuels, maritime transport of fuels, thermal solar energy in buildings, renewable energies, cogeneration and trigeneration, etc.
PL 4. Analysis of thermodynamic cycles with computer software.
The practice consists of learning the use of computer tools for the simulation of power and refrigeration cycles (CYCLEPAD). The practice is oriented to solve problems of cycles (ideal and real) used in the most common thermal machines.
PL 5. Stirling cycle analysis.
An experimental Stirling engine is studied. Different variables that affect the operation of the engine, the cycle and the performance of the engine will be analyzed. The operation of the reverse cycle motor as a cooling machine will also be studied.
PL 6. Experimental study of a heat pump
In this practice the operation of a heat pump will be studied in an experimental facility. Energy balances will be carried out in each of its components to determine its coefficient of operation (COP), working both as a heating machine and as a cooling machine. Likewise, its behavior will be studied in operation as a water-water heat pump and as an air-water heat pump.
PL 7. Introduction to the design of solar cooling installations.
This is a theoretical and demonstrative practice on cooling production installations using solar thermal energy. The aim is for students to learn about an efficient alternative to the use of conventional equipment, whose refrigerants are highly harmful to the environment. |
