Breathing Buildings NVHR+

The incorporation of a heater into the NVHR system allows room pre-heating, and enhanced control over the

temperature of air being delivered to the space during occupancy. The combined LTHW heating and ventilation unit

means the two services are integrated and optimised for the most efficient use of heating and electrical energy.

Heating duty 1.65 kW per NVHR+ unit (3.3 kW per pair)

Heating medium Water entering @80 °C leaving 60 °C @ 0.018 l/s

LTHW connections 15 mm copper tubing

Heating valve 2-port modulating motorised valve

Air flow rate 80 l/s – 130 l/s fresh air per NVHR+ unit (depending on requirements)

Frost protection (full re-circ) If Text < 5 °C or Tint < 12 °C

Morning pre-heat (full re-circ) If Tint < 18 °C hour before occupancy

Occupied-day heating If Tint < target temp while occupied

Specific Fan Power 0.1 – 0.4 W/l/s (depending on grille / ducting arrangement and required flow)

The low energy heating and mixing ventilation system

makes the most of free internal heat gains to temper

incoming fresh air in winter, while also providing:

Frost protection

Pre-occupancy space heating

Enhanced control over mixed air delivery

temperature

Quick-response heating compared to other

heating methods

Avoidance of over-supplying heat to the space

Negates requirement for other sources of

heating in the room

Integral controller and sensors to run feedback

loop

Set-points adjustable via BMS

Automatic with user override

Winter mixing

Summer boost

Automatic summer night cooling

Typically work as single units in small offices

(<10 occupants), multiple units in large offices

and pairs of units in standard classrooms

Morning pre-heat

Occupied day heating
