Refrigeration cycle in the log p-h diagram

 

Refrigeration cycle

 

In refrigeration engineering, the state variables such as pressure, temperature and density are important as is the dependence of these state variables on each other. Using a log p-h diagram, the various state variables can be represented graphically according to their dependencies. Using the log p-h diagram greatly simplifies thermodynamic calculations and is essential for understanding how refrigerating plants work.

Air conditioning in the h-x diagram

 

h-x diagram

 

Air conditioning means affecting the condition of the room air in such a way that people feel comfortable and their capacity is not impaired. The condition of the air is characterised by temperature, pressure and humidity. The basic processes of air conditioning can be represented in the h-x diagram.

GBL symbol From teaching to learning with game-based learning

Game-based learning

Successful learning through play

Using GUNT equipment and the GUNT Science Media Center, you can use the principles of game-based learning to kindle the desire to play and increase the motivation to learn.

 

Use the digital teaching materials, for example, to organise competitions in small groups or between universities.

 

 

Game-based learning

Our concept of hardware and digital features for gamified learning:

 

  • combination of simulation and real-world conditions: Set operating states directly on the device – the effect on the states in theory is directly visible on the monitor
  • run competitions with our online accessible media
  • solve assessments and tasks online
  • videos, animations and augmented reality experiences that enable visual learning and intuitive, playful use of the equipment
