IP HYBRID PROCESS
The sub-cooled refrigerant at point (1)
enters the direct expansion evaporator (6) to
exchange heat with air. During this process
the air becomes cooled and goes into the airconditioned space whilst the temperature of
the refrigerant is increased and the refrigerant
gas pressure remains almost constant.
The superheated low pressure refrigerant then
passes via the compressor (point 2) where its
temperature and pressure is increased due to
the mechanical work done by the compressor.
The thermodynamic properties of the
refrigerant after the compressor (3) creates
high temperature and high pressure gas.
The superheated high temperature & pressure
refrigerant then passes through into the water
storage tank (8) further removing excess
heat using the water via a heat exchanger (9)
inside the water storage tank (8). Due to heat
transfer process the refrigerant temperature is
significantly decreased. Also, as the transparent
tubes (10) are connected to the storage tank
this will assist to reduce the water temperature
via a heat transfer between the glass tubes and
the ambient air.
Condensate water from the evaporator (6) will
continuously add cool water to the storage
tank (8). As a result
the temperature of
refrigerant gas down
line of the storage
tank (point 4) will be
significantly less than
refrigerant temperature
upstream the storage
tank (point 3).
The high pressure
refrigerant after the
storage tank (point 4)
passes the air-cooled
condenser (11) where an

IP Hybrid HVAC Product
Features and Benefits
reduction happens for the refrigerant gas
due to its heat transfer with the ambient air.
Due to pre-cooling of refrigerant before aircooled condenser (in water storage tank), the
refrigerant temperature after the air-cooled
condenser will be considerably less than that
compared to a conventional system that
which does not use water storage tank
hybrid system.
The high pressure refrigerant after the
condenser (point 5) passes the expansion
devices (capillary tube or expansion valve)
where its pressure is reduced. The enthalpy of
the refrigerant after and before the expansion
valve (point 5) and point (1) is almost the same.

on extensive research and development by our
Australian team of engineers.
The water storage tank in our primary design
is located on top of the air-cooled condenser,
however, it can be installed in various
locations between the compressor and aircooled condenser.
Our unique IP Hybrid systems can reduce the
energy consumption as well as greenhouse gas
emissions of your HVAC requirements
reducing peak demand on your site. In cases
of long distances between the evaporator and
condensing unit, a condensate water pump will
be used to deliver the condensate water back
to the water storage tank.
ADDITIONAL FACTS
Our Patented technology can be applied to
any type of air-cooled direct expansion air
conditioning system such as rooftop packages,
DX split systems and Vapour
Compression chillers.
This technology is fully scalable and can be
applied to any size systems.
The compressor in the system can be of any
type such as rotary, reciprocating, scroll, screw.
The refrigerant used can be any type that are
normally used in air conditioning systems such
as R22, R134a, R410A, R407C.
This system can work in all climatic conditions
such as hot & dry, hot &
humid, semi-humid,
moderate and even cold
conditions.
The size of water storage
tank, its transparent tubes
and its heat exchanger are
calculated based on factors
such as climatic conditions,
system capacity and based 1111 / 152 Sturt St. Southbank, Vic. Australia 3006 | www.independentproducts.com.au | [email protected]
