Ventilation solutions that are easy for customers to operate

Many ventilation solutions are overly-complex resulting in HVAC systems which become unbalanced, leading to higher energy bills for building operators and businesses, and wasted hardware that doesn’t fulfill it’s job properly. Hitachi’s approach to ventilation is to simplify, integrating control of the ventilation unit with a VRF, commercial split system or chiller using H-LINK wiring, and in many cases, integrating refrigerant piping into the unit to pre-cool or heat the outside air to unify it with the indoor set temperature.

1-way ventilation units for air renewal in VRF

Hitachi’s Dedicated Outside Air System (DOAS) is 1-way ventilation ducted unit which brings fresh outdoor air into indoor spaces and is available in a range of capacities. It can pre-cool or heat the outside air using the VRF refrigerant loop. This simplifies control of the overall HVAC system by unifying the outdoor air to the set temperature of the indoor air without need to operate and balance separate ventilation and AC systems. Which in turn means less maintenance issues and easier for businesses to operate when HVAC professionals are not around.

2-way ventilation that cuts energy consumption

Energy Recovery Ventilator (TERV030) is a 2-way ventilation solution which uses the energy contained in the air being exhausted from the building to pre-condition the incoming outdoor ventilation air, so that the AC system does not have to work as hard. Compared to using a simple ventilation exhaust fan when running AC, it reduces annual electricity consumption because of the reduced loading on the AC, as the air leaving the building is replaced by air already conditioned to the set temperature indoors.

2-way ventilation designed for VRF or commercial split systems

Because the Energy Recovery Ventilator does not connect to any refrigerant system to pre-condition the air, it can be used in both VRF and commercial split systems through a ducted connection, and can continue to operate effectively when the AC system is switched off. The ventilation unit comes fitted with G5 filter, and an optional CO2 sensor can be installed to enable more precise control of the ventilation based on the levels of CO2 detected in the indoor (exhaust) air stream.
