Introduction

ZEPHIR2 is the Clivet high efficiency package unit handling fresh air

Cuts down pollution

The stale air is extracted whilst fresh air is purified and blown in the space

With a high efficient filtration cuts down consumption

A high efficiency active recovery unit

The exaust air is used by the heat pump as energy source

It eliminates the high pressure drops of the static heat recovery systems

Plant simplification by reducing costs

Thermal/cooling capacity is supplied all year round

with high efficiency

Its energy contribution allows the choice of a smaller peripheral system

Fresh air is a fundamental need

We spend indoors 90% of our time

The quality of the air we breathe is threatened by many

pollution sources.

Indoor, they affect both our health and the building

Outdoor, theyre often more dangerous

Fresh air is a fundamental need

In the commercial sector the fresh air is an essential element

Due to sanitary guidelines and legislation

It causes complications in the choice of the system

The annual energy consumptions are considerable

Due to air displacement (ventilation and filtration)

Due to air handling (temperature/humidity control)

Heat recovery equipment is used

By direct exchange between exhaust and fresh air

It generates considerable pressure drops and further consumptions

Operating principle

The two air flows are always separated

During the summer operation

The exhaust exchanger works as condenser

The fresh air exchanger works as evaporator

The energy produced by the active recovery is transferred to the fresh air

before it is blown into the space

During the winter operation

The cycle reverses

During the middle season

ZEPHIR2 can operate in Freecooling mode withouth the compressor operation

Competitive advantage compared to a traditional system

For the fresh air in the commercial sector we use:

Fresh and exhaust air without recovery

Systems with static heat recovery

Mostly plate/ crossflow type

Systems with rotary heat recovery

Efficient also on the latent portion Other systems are less frequent (run around coil / heat pipe)


12/50


13/50

13 ZEPHIR2 ITA, R01

With the same heating and cooling energy, yielded during the annual cycle in a typical

commercial installation, ZEPHIR 2 in the electronic filters version can reduce up to 50% of

primary energy consumptions than the most frequent traditional systems, considering

production, ventilation and pumping total consumptions.

Active thermodynamic recovery

It doesnt penalize the ventilation

The traditional recovery system

Causes pressure drops of 250 Pa on both air flows

Requires high consumptions for the ventilation

The high consumptions all year round absorbs the recovered energy (non-

sense)

The active thermodynamic recovery unit:

Uses high efficiency exchange coils

Minimizes the pressure drops during the whole operation cycle

Reduces electric consumption for the ventilation

System simplification and reliability increase

The main part of the common system activities are already

manufactured and tested at Clivet factory: It is sufficient to connect the air distribution ducts and supply the unit

Reduction of the starting system costs compared to a traditional solution


21/50

The concept of generator with integrated recovery

Thanks to the heat pump technology applied to the fresh air, ZEPHIR2 is an

high efficiency heating or cooling generator with active thermodynamic

recovery on the exhaust air

The yielded energy reduces the building requirement quota to the auxiliary

generator (start of the system and/or load peaks)

Reducing the global primary energy requirements the

global generating system is more efficient than the

traditional solutions

It increases the building energetic performances,

and its value on the real estate market
