The National Guidelines for Good Refrigeration Practices has been developed by the National ozone Unit (NOU) Environmental Policy and Planning Division, Ministry of Planning and Development, and supports the regulatory framework for the total phase out of Ozone Depleting Substances (ODS) in Trinidad and Tobago by recommending technological options and best practices to reduce the demand for ODSs. These National guidelines are designed to: 1. Define minimum standards of good practices for servicing refrigeration and air conditioning systems, 2. act as a resource document in technicians training and the development of training materials, 3. help to initiate communication between relevant stakeholders, including service companies from the informal sector, 4. Reduce ODS consumption in a cost effective manner, 5. help ensure a smooth transition from ODS to non-ODS refrigeration technology by allowing existing refrigeration systems to run until the end of their useful life, thereby avoiding premature replacement, and 6. Improve safety quality. It is intended that the Guidelines be used as a reference resource for the reduction of refrigerant hydrochlorofluorocarbons (HCFC) and hydrofluorocarbons (HFC) emissions into the atmosphere. It applies to the industrial/commercial, residential domestic appliances, marine refrigeration and air conditioning, mobile refrigeration and mobile air conditioning sectors. National Cooling Strategy The drafting of the NCSTT was guided using a multisectoral consultative approach which spanned a period of over eighteen (18) months. Several key stakeholders involved in the cooling industry, and well as other sectors, in particular as it relates to energy efficiency and alternative refrigerants were consulted across Trinidad and Tobago. These stakeholders included, all Government Ministries, the Environmental Management Authority; the Trinidad and Tobago Bureau of Standards; the National Training Agency; training institutions in the RAC Sector such as the Metal Industries Limited, the National Energy Skills Centre, and the School of Refrigeration and Air Conditioning; research entities such as the University of the West Indies; and Non-Governmental Organizations such as the Air Conditioning and Refrigeration Industry Association and the Refrigerant Recovery and Recycling Association. The NCSTT was circulated to all professionally certified RAC technicians. Comments received were used to finalize the document, under the guidance of the Cabinet Appointed National Coordinating Committee to Guide the Implementation of the Montreal Protocol. The development of the NCSTT was facilitated through funding provided by the Kigali Cooling Efficiency Programme administered through the United Nations Development Programme. …

Blocksystem, Ecological, Smart, Technological! New Variable-Speed R290 (Propane, GWP=3) Air Cooled Packaged System, Plug-N-Play solution for Walk-in Coolers and Freezers. Revolutionary electronics and integrated connectivity system make this future-proof and game-changing product aesthetically appealing, functional and digitally innovative. The thermodynamic circuit, completely revised by using variable speed compressors of the latest generation, electronic expansion valve, EC fan motors and reduced pipes diameter, matches extreme reliability and high performance. New electronics and the new internally developed software, with smart defrost function and leak detector, grant the maximum precision and stability in the temperature regulation and unprecedent energy savings. Specifically designed for walk-in cooler and freezers, BEST will minimize installation time and costs, as there is no need for piping, wiring or plumbing on site. Plus, with only a 4-inch deflector inside the room, storage space is maximized as never before. Smart Controls offer a safe and reliable product with all the comfort to simply manage and monitor these systems from your Smartphone. UL Listed, NSF Approved and DOE / AWEF Compliant. …

We do apply good practice in our servicing department by use of Refrigerant Recovery machine, during maintenance and servicing of the Air conditioning systems. Also during repair works and retrofitting or decommissioning of the systems. …

In Morocco, the rural population still remains important today. A significant proportion of households lives in isolated villages, making rural electrification by connection to the national grid technically more complex and financially more expensive. This is the case for the isolated villages in the northeast of Morocco. It is therefore necessary to consider alternative solutions that would lead to the sustainability of rural electrification. Gepco Solar has installed more than 3000 off-grid solar home systems for isolated homes in rural areas of Morocco. The project improves the lives of more than 15,000 people with no access to electricity. For food preservation, Gepco has developed two refrigerators. Secop supplied its well-proven BD compressors which are equipped with an electronic unit with built-in protection against shortages, operation outside temperature limits and destructive battery discharge.
