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. …
