What Is It?

Thermal energy from the air around you

Unlike solar panels which need direct sunlight, the WSE Hybrid Thermal Air Conditioner uses a Thermal Heat Collector Panel to harvest energy from the ambient environment — roof surface, surrounding air, diffuse heat. This pre-cools refrigerant entering your compressor, so it does less work and draws less electricity. Your cooling comfort is unchanged.

  • Works on cloudy days — no direct sunlight required
  • Compatible with single-split AC units (1 CU : 1 FCU)
  • No need to change existing copper and drain pipes
  • Reduces compressor wear — lower long-term maintenance cost
  • Wall-mounted, ceiling cassette, and ceiling suspended available

Thermal Heat Collector Panel

Roof-mounted. Collects ambient thermal energy day and night. No direct sunlight needed.

2

Outdoor Condensing Unit (CU)

Your existing or new AC outdoor unit — works as normal, just with less runtime.

3

Indoor Fan-Coil Unit (FCU)

Same cool air. Same comfort. Lower electricity bill.

How It Works

The compressor works less. You save more.

1

Collect ambient thermal energy

The Thermal Panel harvests heat from the roof and surrounding air — continuously, regardless of direct sunlight.

2

Maintain efficient refrigerant state

Thermal energy keeps the refrigerant operating in its most efficient state, reducing the work demanded of the compressor.

3

Compressor runs less

Less run time = 20–50% less electricity consumption, with no change in the cooling you experience indoors.

50%
Max electricity reductionThe compressor reduction does not compromise cooling comfort felt and enjoyed by the user.
The reduction in electricity consumption does not compromise the cooling comfort felt and enjoyed by the user.
WSE Hybrid Thermal AC how it works — thermal panel collects ambient energy, compressor runs less, 20–50% electricity saved

Thermal panel collects ambient heat → Compressor works less → 20–50% electricity reduction

Who Is This For?

Great for almost any home or business

🏠

Any Roof Type

No minimum sun hours required — works where solar panels can't.

💸

Budget-Conscious Upgraders

Lower upfront cost than a full solar AC system. Works alongside your current AC.

🔧

Existing AC Owners

No pipe replacement needed. The panel augments your current single-split system.

System 3

WSE Hybrid Thermal Inverter System 3

A System 3 configuration powers three indoor fan coil units (FCUs) from a single outdoor condensing unit — ideal for homes and offices needing whole-space cooling at 20–50% lower electricity cost.

Key highlights

1

3-room whole-home coverage

One outdoor condensing unit powers three indoor FCUs simultaneously — ideal for landed homes, offices, and retail spaces of 20–25 m² each.

2

Eco-friendly R32 refrigerant

R32 has significantly lower global warming potential than older refrigerants — better for the environment without sacrificing cooling performance.

3

NEA 5-tick rated

Rated Excellent by Singapore's National Environment Agency for energy efficiency. Qualifies for government energy efficiency rebates.

4

No direct sunlight required

The thermal panel harvests ambient heat from the surrounding air — works on any roof orientation, even in shade.

Annual energy cost rated at S$1,064 — delivering 20–50% savings vs a conventional system of comparable cooling capacity.
