What Makes
An Aqua Systems Evaporator Work So Well?
A High Performance
Heat Exchanger Will Substantially Improve Heat Pump Performance
| 1) |
Water
enters the upper two tubes. As it passes through the tubes,
turbulence of the water is maintained, even at low water flow,
due to the internal rifling of the tubing. |
 |
| 2) |
Refrigerant
liquid enters via the lower refrigerant tube and is forced to
follow a long spiral flow path. This flowpath is created by
the tight tolerance between the copper tubing and the steel
side walls. |
| 3) |
The enhanced
surface of the copper tubing, 3.7 times that of smooth tubing,
releases heat from the water side. The spiral and axial refrigerant
flow causes rapid evaporation of the refrigerant, resulting
in a very low pressure drop on the refrigerant side and no oil
trapping. |
| 4) |
As the
liquid refrigerant absorbs heat from the water it begins to
boil off, exiting the heat exchanger as a gas. |
| 5) |
The water
tubes cross over at the mid point of the heat exchanger. The
outside tube becomes the inside and the inside becomes the outside
tube. This results in two tubes exactly the same length, with
equal pressure drop and equal heat exchange. |
| 6) |
The cooled
water exits the two lower water tubes. |
Benefits
of Using Aqua Systems Condensers in Water Cooled Air Conditioners.
Models 1.5 Tons to 57 Tons.
AQUA SYSTEMS refrigerant
to water heat exchangers incorporate the latest in refrigerant heat
exchanger technology. The compact size and the high level of heat
exchange efficiency are achieved by the Aqua Systems unique heat exchange
tube geometry.
The enhanced
surface of the copper or cupro nickel tube provides surface extension
of 3.7 times that of smooth tubing. The conical, co-axial design
of the water coils and the internal rifling ensures that water turbulence
is maintained even at low water flow rates.
On the refrigerant
side, the close tolerances between the water coils and the condenser
shell, result in the extraordinary heat exchange performance during
condenser duty on the cooling cycle. As they are designed to also
suit reversible applications, the unique design provides a high
level of performance when the heat exchanger is used as a liquid
chiller.
|
Some
of the features which make the Aqua Systems heat exchanger
the best condenser choice are as follows:
| 1) |
Close
approach temperature between the Refrigerant Condensing
Temperature and the Leaving Water Temperature reduces
the volume of condenser water to be circulated. Reduces
the size of condenser water pipes and circulating pumps.
|
| 2) |
Efficient
Liquid Refrigerant Sub Cooling as the leaving liquid is
subcooled by the entering water due to the counterflow
design enhancing system efficiency. |
| 3) |
Drainable
water tubes due to the spiral design allows easy draining
of the water tubes for freeze cleaning. |
| 4) |
Freeze
cleaning of the water tubes after draining, allows rapid
condenser cleaning with minimum downtime and no mess.
Eliminates the use of chemicals. |
| 5) |
NO
oil trapping as a result of the close tolerances in the
refrigerant path. |
| 6) |
Improves
heat pump performance with high BTU output at low water
temperatures. |
| 7) |
Low
water side pressure drops reduces pump size and operating
costs. |
| 8) |
Continuous
water coils with no internal joints has less chance of
leaks. |
| 9) |
Compact
size convenient cylindrical shape is easy to insulate.
|
| 10) |
Reliable
operation, as all AQUA SYSTEMS heat exchangers are tested
to 530 psi after manufacture. |
| 11) |
UL®
listed. Complies with Australian Standard 2971-1987 Serially
Produced Pressure Vessels. |

Aqua Systems
the Best Marine Water Cooled Condensers for Refrigeration
or Air Conditioning Installations.
Compact and Low Fouling.
AQUA SYSTEMS
"CN" Series marine refrigerant condensers incorporate the latest
in refrigerant heat exchanger technology. The compact size and the
high level of heat exchange efficiency are achieved by the Aqua
Systems unique heat exchange tube geometry.
The enhanced
surface of the cupro nickel tube provides surface extension of 3.7
times that of smooth tubing. The conical, co-axial design of the
water coils and the internal rifling ensures that water turbulence
is maintained even at low water flow rates.
Low Fouling
due to the elimination of low velocity spots and the allowable increase
in leaving water temperature reduces spot scaling and inhibits fouling
due to mollusks.
