Energy(Heat) Recovery Ventilator

Panasonic Energy recovery ventilator can reduce the outside air load because they efficiently recover the heat lost by ventilation during the heat recovery process. This results in energy-saving ventilation and lower running costs for air-conditioner and heating equipment.

Feature

1. Energy saving ventilation:
   Energy consumption is dramatically reduced by using an counter-flow heat exchange elements. The air conditioning load is reduced by about 20%, resulting in significant energy saving
2. Slim design:
   A slim shape saves on installation works: Compared with the cross flow configuration, the counter-flow elements is more compact and slim.
3. Structure:
   The counter-flow heat exchanger elements requires no regular cleaning.
4. Quiet operation:
   Low noise operation results in noticeably quieter unit.
   
5. Product Range Air Volume:
   250cmh, 350cmh, 500cmh, 800cmh, 1000cmh in total 5 models
   Enthalpy exchange efficiency: at Cooling( from62% to 69%), at Heating( from from 67% to 74%)

Dramatic energy saving achieved through adoption of a high-efficiency counter-flow heat-exchange element.

1. Building apartment (Each floor independently air-conditioned)
2. Area of middle floor: 80m2
3. Indoor load:summer, winter and autumn 80m2 x 120kcal/hm2 x 4.2=40,320kj/h-(1)
4. Room temp&Humidity
   Room temp Cooling 26degreeC(RH50%) ,Heating 20degreeC(RH50% Outside Temp 33degreeC(RH63%), Heating 0degree C(RH63%)
5. 1000 hours od operation in each season
6. Ventilation rate: 20x80/3=533=500m3/h
7. Ventilation load when a ventilation fans is used during cooling 500x7.6kcal/kgx1.2x4.2=19,150kj/h-(2)
8. Ventilation load when energy recovery ventilation is used during cooling 500x7.6kcal/kgx(1-0.62)x1.2x4.2=7,280kj/h-(3)
