ASED Consulting International Pty Ltd, are clear advocates of energy efficiency and sustainability, we have designed many ammonia and carbon dioxide-based refrigeration systems that incorporate freezing, cooling and heating duties to entire facilities, as follows:
Freezing & cooling loads, such as:
- Blast freezer loads at the ultra-low temperature range
- Storage freezer loads at the low temperature range
- Cool rooms and processing room loads at the medium temperature range,
- Liquid chilling loads at the medium temperature range
- Process cooling and air conditioning loads at the high temperature range,
Heating & heat pump loads, such as:
- Hot gas defrosting for ultra-low and low temperature evaporators
- Warm glycol defrosting loads to meet evaporator defrosting duties
- Warm glycol reticulation for sub floor heating and frost heave prevention
- Humidification, dehumidification loads and duties
- Hot water for facility wash-down
- Boiler water pre-heat and replacement.
The integrated refrigeration & central energy system solution is a bespoke highly energy efficient design fulfilling a multitude of refrigeration, freezing, process cooling and heating requirements, which would otherwise require multiple mechanical, electrical and controls systems working individually to achieve the same outcome. However, the latter, at a higher initial installation cost and ever-growing service and maintenance cost.
Energy Efficiency and Operational Advantages
An integrated energy and central energy refrigeration, process cooling, process heating, and heat pump system represents a paradigm shift in thermal management, offering a multitude of inherent advantages over conventional decentralised system approaches, with a focus on energy efficiency, capital expenditure (Capex), and operational expenditure (Opex), such integrated systems emerge as a compelling choice for facility owners seeking sustainable and cost-effective solutions.
Maintenance and Lifecycle Benefits
Integrated energy and central energy refrigeration, process cooling, process heating, and heat pump systems offer a holistic approach to thermal management, consolidating multiple functions into a centralised infrastructure, by integrating cooling and heating capabilities within a single system, facility owners stand to reap numerous benefits, foremost among them being enhanced energy efficiency. Unlike conventional decentralised, or multiplexed refrigeration, air-conditioning and heat pump systems, which often operate independently, lack efficiency, and cost significantly more than a centralised energy system. Integrated systems leverage centralised control and optimisation algorithms to synchronise operations, minimise energy wastage, and maximise overall system efficiency.
Furthermore, integrated systems offer significant advantages in terms of Capex and Opex, by centralising equipment and infrastructure, such systems streamline installation, reduce the number of cooling and heating equipment, and optimise space utilisation, resulting in lower upfront capital costs.
Centralized Resource Management
Additionally, centralised control and monitoring enable proactive maintenance scheduling, predictive diagnostics, and efficient resource allocation, leading to reduced maintenance expenses and prolonged equipment lifespan. Moreover, centralised procurement and management of energy resources, such as electricity, gas and refrigerants, enable economies of scale and bulk purchasing discounts, further driving down operational costs over the system’s lifecycle.
Operational Streamlining and Reliability
In addition to the tangible cost savings, integrated systems offer intangible benefits such as streamlined operations, simplified maintenance, and enhanced reliability, with a unified control interface and centralised monitoring, facility operators gain real-time visibility into system performance, enabling proactive troubleshooting, rapid response to anomalies, and seamless integration with building automation and energy management systems. Moreover, by consolidating equipment and infrastructure within a centralised plant room or energy center, integrated systems minimise the footprint and visual impact of mechanical installations, enhancing architectural aesthetics and spatial flexibility.
Conclusion: Value Proposition of Integrated Systems
In conclusion, integrated energy and central energy refrigeration, process cooling, process heating, and heat pump systems present an attractive proposition for facility owners looking to invest in sustainable, efficient, and cost-effective thermal management solutions, by combining energy efficiency, streamlined operations, and cost optimisation, such integrated systems offer a compelling value proposition, empowering facility owners to achieve their sustainability goals, enhance operational resilience, and realise long-term cost savings while maintaining a competitive edge in today’s dynamic marketplace.
