C&R 2021 will be held from 16th to 19th November at IFEMA MADRID

In partnership with AGREMIA, the Workshop on Applied Air Conditioning Techniques will focus on best practices in installations. It will also emphasise indoor air quality, the importance of awareness about current regulations, zero or near-zero consumption in residential buildings from renewables, and the versatility of photovoltaic solar energy.

The Refrigeration Workshop is organised in partnership with AEFYT (Association of Refrigeration Technologies Companies). It will cover seven different practices each day, addressing a series of issues and techniques involved in installing and assembling refrigeration systems.

To promote best installation practices, two training workshops: an APPLIED AIR CONDITIONING TECHNIQUES (TAC) WORKSHOP and a REFRIGERATION WORKSHOP, will again be an important part of the parallel programme at the next edition of Air Conditioning and Refrigeration Exhibition, C&R 2021. The Fair will take place from 16th to 19th November at IFEMA MADRID.

The TAC Workshop is organised by the Association of Companies in the Installations and Energy Sector, AGREMIA. It will include four thirty-minute demonstrations for the Air Conditioning & Ventilation and Heating & Domestic Hot Water sectors.

The first workshop will be Ventilation System – Extraction with Energy Recovery and CO2 Detection Systems in Indoor Environments. This workshop is aimed at the Air Conditioning and Ventilation sector. It will focus on indoor air quality and sanitisation, a subject of growing interest, especially during the current pandemic. The demonstration will cover important innovations and systems currently available on the market (including forced extraction systems, energy recovery systems, CO2 detectors). The demonstration will explain to attendees the significant differences and advantages between a conventional ventilation and extraction system and another equipped with energy recovery, from the point of view of final energy efficiency and safety and comfort.

The second workshop will cover Handling Fluorinated Equipment and Replacement With Eco-friendly Gases, under Royal Decree 115/2017. It will cover the technical and regulatory changes introduced by the new Royal Decree 115/2017 on handling, emphasising leakage control and documentation procedures with the required traceability. The workshop will be carried out on a split domestic air conditioning system in operation with all its parts and the equipment needed for correct handling (for example, recovery unit, vacuum pump, scale, gauge bridges, leak detection, digital thermometers). It will also cover the situation regarding replacing conventional fluorinated refrigerants with those popularly called eco-friendly, which contain none or very little. It will also review the technical aspects of these new refrigerants (such as R-290, R-32, CO2).

For the Heating and ACS sector, the workshop on Aerothermal and Geothermal Renewable Energy will demonstrate to the attendees that it is already technically possible to achieve zero or almost zero consumption in residential buildings with a mix of different types of renewable energies. The Workshop will focus on geothermal and aerothermal, and the latter as a general solution when geothermal installation is not feasible. In both cases, the energy support from photovoltaic solar installations provides the renewable energy necessary to operate the entire system.

The second workshop will also look at Applying Photovoltaic Solar Energy to Heating and Air Conditioning. It will demonstrate the diverse applications and versatility of this type of energy, even for uses other than straightforward home heating installations (such as electric vehicle charging, lighting, and swimming pools). The workshop will focus primarily on new systems for storing surplus energy from these sources as heat. This storage consists of superheating DHW and storing it in buffer tanks for later use. This technique can overcome a significant problem with this type of energy and can be a perfect replacement for lithium batteries with their drawbacks.

Refrigeration Workshop

The Refrigeration Workshop is aimed at refrigeration technicians and organised by the Spanish Association of Companies of Refrigeration and its Technologies, AEFYT, in partnership with the Moratalaz Training Centre for Cold and Air Conditioning Technologies. Each day it will address several issues around the installation and assembly of refrigeration systems.


The Refrigeration Workshop morning and afternoon sessions will have a training format covering seven different practices: Assembling A Cold Room With a Waterloop Unit; Glycol Cooling System; Assembling a CO2 Transcritical System With Refrigeration Units; Assembling a Refrigeration Panel with a Waterloop Unit; Handling Other Free-standing Materials; Gas Detectors; Electrical Cabling From the Central Electrical Panel To Each of the Services, and finally the topic Towards Industry 4.0: Monitoring Different Systems and Migrating Data To the Cloud.


The following partner companies are collaborating with C&R in the Refrigeration Workshop: INTARCON, INFRICO – CORECO, COLDKIT, TEWIS, CLIMALIFE, FROSTROL, DICOSTOCK, EXKALSA and AKO.
