WHERE IS THE MONEY
Simple calculation by using times, division, addition and minus
Plan A: NZ Home, 1.5 billion dollars saving every year use solar
Plan B: Auckland Bicycle, 1 billion dollars patrol saving every year
Plan C: Non Driver Bus, 1 billion dollars wages saving every year
Plan D: NZ Bus, 250 million dollars saving every year
Total saving: $3.75 billion every year
I can save more than this money!
BUILDING ENERGY COST
Building energy cost1st Air Conditioning: 50%
2nd Hot water: 20%
3rd Lighting: 10%
4rd Appliance: 10%
4th Other: 10%
Saving cost, Saving money
TRANSPORT FUEL COST
4,300,000 population, 3,087,400 vehicle
Every vehicle cost patrol $10 dollars per week
assumption
$1.6 billion dollars on the patrol every year
PLAN A: 1.5 BILLION DOLLARS EVERY YEAR
NZ: 4,300,000 people, 1,000,000 home
$20 per month hot water shower bill per person
Total cost: $20 ×4,300,000×12=$1,032,000,000 every year
LED bulb: 50W bulb can be changed to 3W LED Bulb
Total saving: 50 × 3×1,000,000 ×4×365×$0.2/1000 × ( 1 + 10)
= $482 million
This can be saved by using free solar energy: 1.032+0.482 =
1.514 billion
PLAN B:1 BILLION DOLLARS EVERY YEAR
$1.6 billion dollars patrol can be saved to $1 billion
dollars
Danmark: 5,000,000 people, 4,000,000 million
bicycles
Auckland: 1,400,000n people, 1,000,000 bicycles
20 dollars patrol saving by using bicycle every
week
1,000,000×20 ×52 = $1 billion dollars every year
can be saved
There is no congestion in NZ
People will more healthy by exercise and clean air
PLAN C: 1 BILLION DOLLARS EVERY YEAR
50 millions NZBUS movement every year
1 hour every movement assumption
20 dollars per hour average wages
50 ×20= $1 billions dollars wages every year
It can be saved by using non driver buses
PLAN D: 250 MILLION DOLLARS EVERY YEAR
10 bus running: 9 bus empty
50 millions NZBUS movement every year
4 liters diesel per movement assumption
1.5 dollars per liter diesel
50 ×4 ×1.5 = $300 millions dollars fuel every year
Small bus plus Energy saving bus only use $50 millions
dollars fuel every year
$300 - $50 = $250 millions dollars can be saved every
year

AUCKLAND UNITARY PLAN
Solar show house in Onehunga
Solar show building in Newmarket: the University of
Auckland
LED show walk way in Ponsonby Park
Single route show bicycle way with solar recharge
station from Onehunga to Newmarket
Small bus running show route: Dominion road
AUCKLAND UNITARY PLAN
CBD to Airport train ? No, CBD to Airport non driver bus
plan and bicycle bridge plan and non-driver bus plan !
Beautiful way (visionibility, Three-dimensional transport)
Economic way (cheap and quality design)
People first choice (safe, fast, healthy, anti-rain, non-
congestion, environment friendly, non fuel cost)
Don’t damage the property (bridge along the current
road)
AIR CONDITIONING
Humidity Control
• Cost more energy
Temperature
Control
• Cost less energy
SOLAR COOLING
Humidity Control
• Liquid Desiccant
Temperature
Control• Solar Power
LIQUID DESICCANT ADVANTAGES
Smaller air pressure drop: Cheap running fee
Pump: Suit large building
Tank: Suit solar energy
LIQUID DESICCANT HISTORY
Liquid desiccant dehumidification technology has been
commercially available since 1935.
The latest commercial liquid desiccant dehumidifiers are
supplied by Niagara Blower Company (Kathabar dehumidification
systems), DuCool company (DuTreat, DuHandling, DuHybrid
Series), L-DCS Technology Pte Ltd (200kW dehumidifier).
Most of these systems use LiCl as liquid desiccant. Kathabar
Kalsorb system use CaCl2 as liquid desiccant.

DESIGN FOR NZ
Lord of the Ring
Volcanic peaks, rolling pastures, lush forests and icy glaciers
Milford Sound is one of New Zealand’s most popular tourist
destinations and also long considered the country’s officially
wettest location.
However, portions of the western Fiordland and Westland of
the Southern Alps are estimated to be the wettest on earth.

HOUSE DESING FOR NZ
HOME IMPROVEMENT
CONVENTIONAL VCS
Challenge to the tradition, that’s the secret to be
the leader
Conventional vapour compression air conditioning
systems (VCS) cool the air below its dew point to
condensate the water vapour in the air, followed by
reheating of the air to a comfortable temperature.
Liquid desiccant cooling system: The pre-cooled
desiccant system can not only dehumidify plant air,
but also can cool the plant air

STRUCTURE
DESICCANT SOLUTION
LiCl, TEG and CaCl2
Lithium chloride: expensive, stable, regeneration at 80 ºC,
corrosive, high performance dehumidification, plastic storage
Calcium chloride solution: cheap, unstable, cheap storage,
regeneration at 60 ºC, corrosive, plastic storage
TEG: earliest, evaporate, regeneration at 65 ºC to 80 ºC
Mixture of LiCl and CaCl2: higher performance
DRIVING FORCE
vapour pressure difference between the gaseous air and
the liquid desiccant
When the air vapour pressure is higher than the liquid
vapour pressure, dehumidification takes place
When the air vapour pressure is lower than the liquid
vapour pressure, regeneration occurs.
The capacity of the water vapour removal rate can be
determined by the vapour pressure of the liquid desiccant
COUPLED HEAT AND MASS TRANSFER
Mass transfer and heat transfer
The heat transfer process involves the temperature
difference and absorption heat released
condensation of vapour and the heat of mixing
The heat from the air and absorption raises the solution
vapour pressure. This reduces the capability of the desiccant
to absorb more vapour
As heat is transferred away from the surface, the liquid
desiccant becomes capable of absorbing additional vapour

OPERATION
Energy storage: solar energy battery
Concentrated desiccant can be stored in uninsulated plastic
tanks with no loss in cooling potential over time
match cooling loads with the availability of solar energy
The concentrated salt solution can also be transported over long
distances without losing any of its air dehumidification ability
solar panels produce three times more energy than required for
air dehumidification on clear days
OPERATION
Pressure drop knowledge
Pump and fan size
The optimal analysis is to attempt to decrease the
pressure drop and improve the heat and mass
transfer performances while minimizing the initial
cost e.g. packing volume
