Heat Recovery for Swimming Pools and Leisure

Leave a comment
Applications

Why It Matters

Pools lose heat through evaporation and constant ventilation of humid air. Recovery captures energy from that exhaust and slashes the heating bill.

Typical Energy Savings

Exhaust-air recovery combined with a pool heat pump can cut heating energy by 40 to 60 percent.

Recommended Technology

  • Plate or rotary exchangers on pool hall ventilation
  • Heat-pump desuperheater recovering compressor heat

What to Watch

  • Corrosive, chlorine-laden air needs coated, cleanable surfaces
  • Control humidity to protect the building fabric

Heat Recovery for Laboratories and R&D

Leave a comment
Applications

Why It Matters

Labs exhaust large volumes for safety, creating a heavy conditioning load. Recovery lowers that load while maintaining the strict air changes required.

Typical Energy Savings

Sensible recovery on make-up air commonly removes 50 to 70 percent of the heating and cooling demand.

Recommended Technology

  • Plate cores where airstream isolation is mandatory
  • Run-around or coil systems for contaminated exhaust

What to Watch

  • Never mix fume-hood exhaust with supply air
  • Balance energy savings against safety and containment

Heat Recovery for Industrial Manufacturing

Leave a comment
Applications

Why It Matters

Factories exhaust warm air from processes, welding, and general ventilation. Capturing that energy reduces purchased heating and can pre-heat incoming make-up air or process streams.

Typical Energy Savings

Make-up air recovery often cuts heating energy by 40 to 60 percent in heated plants with high exhaust rates.

Recommended Technology

  • Plate or heat-pipe exchangers for make-up air
  • Run-around coils where exhaust is contaminated

What to Watch

  • Dust, fumes, and corrosive exhaust need robust, cleanable cores
  • Comply with process and safety codes for the specific industry

Heat Recovery for Greenhouses and Horticulture

Leave a comment
Applications

Why It Matters

Greenhouses vent warm, CO2-rich air to control temperature, wasting both heat and the fertiliser CO2 plants need. Sensible recovery keeps the energy while the gas stays in the canopy.

Typical Energy Savings

Recovering heat from vents can cut heating demand during cold nights by 20 to 40 percent and reduce supplemental CO2 dosing.

Recommended Technology

  • Sensible plate cores - heat only, no moisture or gas transfer
  • Run-around coils where airstreams must stay separate

What to Watch

  • Humidity management to avoid condensation issues
  • Control strategy that prioritises crop conditions

Heat Recovery for Schools and Universities

Leave a comment
Applications

Why It Matters

Schools ventilate heavily during occupied hours and must protect indoor air quality for students. Recovery does both while controlling operating cost.

Typical Energy Savings

Plate-based recovery commonly removes 55 to 75 percent of the ventilation load across classrooms and halls.

Recommended Technology

  • Crossflow plate cores in rooftop or central units
  • Demand-controlled ventilation tied to CO2 sensors

What to Watch

  • Summer bypass to avoid overheating when cooling is unneeded
  • Easy filter access for custodial staff

Heat Recovery for Hotels and Hospitality

Leave a comment
Applications

Why It Matters

Hotels ventilate lobbies, kitchens, laundry, and hundreds of rooms around the clock. Recovery improves guest comfort while lowering energy cost per occupied room.

Typical Energy Savings

Central recovery can reduce ventilation-related heating and cooling by 50 to 70 percent, with portfolio-wide impact.

Recommended Technology

  • Rotary wheels for large central AHUs
  • Plate cores for zone or suite-level units

What to Watch

  • Kitchen and laundry exhaust carry grease and moisture - filter and clean
  • Noise and vibration control for guest areas

Heat Recovery for Commercial Offices

Leave a comment
Applications

Why It Matters

Offices ventilate during long occupied hours. Older constant-volume systems throw that conditioned air away, wasting heating and cooling simultaneously.

Typical Energy Savings

A crossflow plate core typically cuts the ventilation heating and cooling load by 50 to 70 percent.

Recommended Technology

  • Crossflow plate core - simple, compact, low maintenance
  • Integrated heat-recovery ventilator for retrofits

What to Watch

  • Confirm the fan can handle added static pressure
  • Pair with demand-controlled ventilation for extra savings

Heat Recovery for Cold Storage and Freezers

Leave a comment
Applications

Why It Matters

Cold stores continually introduce warmer make-up air and run defrost cycles, both of which add load to refrigeration. Recovery trims that load and eases compressor runtime.

Typical Energy Savings

Pre-cooling incoming air with exhaust can reduce refrigeration energy by 10 to 25 percent depending on climate and door traffic.

Recommended Technology

  • Plate cores sized for low face velocity
  • Defrost strategy matched to the coldest design point

What to Watch

  • Frost on the core in very cold intake conditions
  • Hygiene and drainage in food-grade stores

Heat Recovery for Food and Beverage Processing

Leave a comment
Applications

Why It Matters

Food plants use heat for pasteurisation, drying, and cleaning, then vent warm, often humid air. Capturing that energy lowers both utility cost and carbon.

Typical Energy Savings

Exhaust-air recovery paired with a heat pump can cut process heating demand by 30 to 50 percent in suitable lines.

Recommended Technology

  • Plate exchangers for make-up air pre-treatment
  • Run-around coils or heat pipes where airstreams must stay separate

What to Watch

  • Use hygienic, cleanable surfaces and food-grade materials
  • Manage condensate and grease in exhaust streams

Heat Recovery for Pharmaceutical Cleanrooms

Leave a comment
Applications

Why It Matters

Cleanrooms run hundreds of air changes per hour, so the ventilation load dwarfs the rest of the building. Recovery here protects product integrity while cutting cost.

Typical Energy Savings

A sensible plate exchanger can recover a large share of the make-up air conditioning load without any stream mixing, preserving classification.

Recommended Technology

  • Stationary plate cores - no moving parts, full separation
  • Pre-cool and pre-heat before HEPA filtration

What to Watch

  • Zero cross-contamination is non-negotiable - avoid rotary wheels
  • Pressure-drop budget must respect the cleanroom fan system
