Best practicePROHeat2o significantly reduces overall energy costs by maximizing chiller performance and effectively recovering waste heat.
PROHeat2o exemplifies best practices in heat recovery with its 2-step Heat Recovery Process, making use of waste heat for a variety of applications. The system is factory-installed within the standard chiller housing and is available on ALL PROChiller System models. In Step 1, waste heat from the refrigerant is harvested through a brazed stainless steel heat exchanger refrigerant-to-glycol water “recovery” loop. The closed “recovery” loop temperature closely follows the discharge refrigerant temperature. In Step 2, a second fluid-to-fluid heat exchanger is then utilized to pre-heat potable water for the customer. The pre-heated water feeds into the customer’s traditional water heating equipment, reducing (or even eliminating) their fossil fuel heating needs. This process allows for multiple benefits versus a single-step heat recovery system: • Lowered Energy Consumption: By utilizing otherwise wasted energy, PROHeat2o minimizes the consumption of electricity, propane, or natural gas for heating water, resulting in reduced energy bills and a smaller carbon footprint. Additionally, the system's dual fluid pumps can be turned on or off based on hot water demand, which adds to operating cost savings. • System Protection: By separating the Refrigerant from the potable water supply, PROHeat2o safeguards both the refrigeration system and the potable water supply, preventing potential damage or contamination. • Cost-Effective Maintenance: Expensive refrigeration repairs caused by low water quality are eliminated by the fluid-to-fluid heat exchanger for potable water heating. When heat exchanger fouling occurs, the low cost fluid to fluid heat exchanger is easily cleaned, or replaced, without extended downtime or high service costs. …
Best practicePROGreen Solutions Chiller Systems Use Carbon Dioxide, R744, as a Refrigerant
Utilizing carbon dioxide (CO2 or R744) as a refrigerant offers numerous environmental benefits, such as low global warming potential (GWP) and zero ozone depletion potential, as well as long-term financial benefits to the user. Continuous improvement and staying up to date with industry advancements are key to optimizing the use of CO2, and the PRO Refrigeration team does exactly that with their PROGreen Solutions team. • Environmental Impact: CO2 (R744) has a Global Warming Potential (GWP) rating of 1, meaning it has no impact on global warming. In comparison, PRO's other equipment uses the refrigerant R404A with a GWP of 3,900. By adopting CO2 refrigerant, PRO significantly reduces carbon emissions and contributes to environmental sustainability. • Energy Efficiency: CO2 systems can operate above the trans critical point, allowing for increased heat recovery of more than 100%. By generating hot water even during low cooling load and low ambient periods, CO2 system users can eliminate the need for fossil fuel heating sources while shrinking their carbon footprint. • Cost Efficiency: CO2 refrigerant costs are currently 95% lower per pound than common chemical-based refrigerants. Utilizing CO2 recovered from the atmosphere, PRO is eliminating the need for expensive synthetic refrigerants that all have a future phase-out date. …

Best practiceTranscritical CO2 Condensing Units and Split Systems
Thanks to the experience gained over the years in the world of R744 natural refrigerant products, Rivacold integrates their NatRef portfolio with the MHX, a new range of Transcritical CO2 condensing units with semi-hermetic compressors. The MHX circuits have been optimized to achieve high performance and energy efficiency. The semi-hermetic compressors, the EC fans, the specific components required by the use of the R744 gas and a customized electronic control software allow savings of 7% compared to a traditional R404a system with semi-hermetic compressor and AC fans. MHX meets all the needs of the food retail, c-stores, large distribution and logistics sectors, ensuring high performance, maximum reliability, safety and energy saving, also thanks to the inverter on the compressor. Furthermore, the integrated gas cooler makes this solution compact, easy to transport and install, even in residential areas thanks to the optional soundproofing levels. These units offer capacities up to 120000 BTU/h and are sized to operate in ambient temperatures up to 110°F, always guaranteed by Rivacold quality. Energy efficiency, eco-sustainability and perfect food conservation are always guaranteed by Rivacold. UL Listed and DOE /AWEF Approved. …

Best practice• Collaborative join venture in the development of National Guidelines for Refrigeration and Airconditioning Sector & The National Cooling Strategy
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. …
