BAC Ice Thermal Storage

As the name suggests, they use ice to build and store cooling when cooling demand and/or energy rates are low (mostly overnight), which the system then uses for air-conditioning or process purposes when energy rates are high (mostly daytime).

Key benefits of ice thermal storage

fulg icon

Refrigeration systems up to 50% more compact

economy-saver

Operational cost savings: ice formed overnight with cheaper electricity

energy_saver

Lower energy consumption basing the cooling system on average conditions rather than peak reduces power requirements and the refrigerant charge

Asset

Reduced carbon footprint: Most of the cooling occurs overnight when condensing temperatures are lower and the cooling system requires less energy

meintenance

Less compressor maintenance since the compressor operates continuously at full capacity and not under fluctuating partial load

Thermal storage systems provide back-up cooling

ICE THERMAL STORAGE
TSU-C/D

Overview

The TSU-C/D is an external melt system. Direct ice/water contact ensures a constant low water temperature. External melt is ideal for applications requiring constant near-freezing water temperatures (1 to 2°C).

Other benefits are:

– Minimum maintenance

– Environmentally friendly

– Proven technology

Principle of Operation

The TSU-C/D is an external melt system that produces and builds ice (1) around a coil (2) submerged in water (3). A refrigerant or cold glycol (4) circulates through this, while ice accumulates on the outside. The ice is melted by circulating warm water (5) from the load over the coil, which cools the water (6). Low pressure air (7) from an air pump (8) is distributed below the coil for water agitation.

Key benefits

  • Reliability: constant water supply temperature (1 to 2°C)
  • Lowest first cost
  • Energy saving

Typical applications

  • Food processing
  • Breweries
  • Dairies

ICE THERMAL STORAGE
TSU-M

Overview

TSU-M is an internal melt system. Internal melt is ideal for air-conditioning involving cooling at higher temperatures.


Other benefits are:

– Constant supply temperature regardless cooling demand

– Minimum maintenance

– Environmentally friendly

– Proven technology

Principle of Operation

TSU-M is an internal melt system that produces and builds ice (1) around a coil (2) submerged in water (3), most of which freezes within the tank. The warm glycol (4) from the load circulates through the coil and melts the ice from the inside. The newly cooled glycol (5) is then pumped through the building cooling system or used to cool a secondary refrigerant that does the same.

Internal melt is ideal for air-conditioning involving cooling at higher temperatures than external melt.

Key benefits

  • Lowest first cost
  • Energy saving
  • Reliable

Typical applications

  • Air conditioning

ICE THERMAL STORAGE
TSC

Overview

TSC features only a coil for ice thermal storage applications. The concrete tanks housing this are typically part of the building infrastructure.


Other benefits are:

– Proven BAC technology, part of your building infrastructure

– Minimum maintenance

– Environmentally friendly

Principle of Operation

The TSC coil is for use in an external melt system. This system produces and builds ice (1) around a coil (2) submerged in water (3). A refrigerant or cold glycol (4) circulates through this, while ice accumulates on the outside. The ice is melted by circulating warm water (5) from the load over the coil, which cools the water (6). Low pressure air (7) from an air pump (8) is distributed below the coil for water agitation.

Key benefits

  • Reliability: constant water supply temperature (1 to 2°C)
  • Lowest first cost
  • Energy saving

Typical applications

  • Air conditioning
