Calculates the design heating and cooling loads and associated psychrometrics for air conditioning plant in buildings. CAMEL is one of the leading air conditioning load estimation programs used in Australia and New Zealand. The calculations are based on the AIRAH/IHRACE Application Manual DA9 "Air Conditioning Systems, Load Estimation & Psychrometrics" which incorporates the cooling load estimation techniques and data developed by the Carrier International Corporation with considerable extensions and refinements to these methods and data, developed by ACADS-BSG. It models buildings in the Southern and Northern Hemisphere.

CAMEL models a range of system types including CV Heating and Cooling, CV Face and Bypass VAV with and without reheat, RC Heat Pumps and Evaporative Coolers and each AHU can serve a number of zones which can in turn have a number of rooms. Plant fresh air quantities can be calculated in accordance with AS1668.

Expertise Required: 

Knowledge of air conditioning systems and thermal heat transfer is of advantage. A one day training course is recommended.

Audience: 

HVAC design engineers and contractors, local government and university teaching departments.

Input: 

The geometric details of the building including shading schemes and the internal people, lights and equipment loads. A large selection list of walls and roofs is available with pre-calculated U values and surface densities.

Monthly design data for over 700 locations in Australia is stored in the program and locations for other countries are also available. Design conditions based on 3pm summer design conditions, daily range and yearly range for any other location can also be entered.

Graphical displays are provided for schedules, shading schemes and for each external wall or roof as it is entered providing a convenient visual check for the user.

Buttons on the toolbar and special keys allow the user to copy individual values, columns of data or complete screens from zone to zone and there is a facility for making global changes.

Comprehensive range and data checking is provided on all input items and a comprehensive consistency check is made on the data entered. Comprehensive help is provided on all input items.

Output: 

The results include cooling, heating and reheat loads, air quantities, VAV turn down ratios, check figures, etc, and these can be selectively or collectively viewed with a special viewing and printing program. The program also provides graphs of loads, air quantities, etc, psychrometric chart plots and a dynamic graphical display of the shadows on walls and windows from overhangs reveals and adjacent buildings.

Strengths: 

The program has many features that make the inputting of data quite simple and user friendly and through the ongoing development process over thirty years it has now become the most widely used and practical load estimation program in Australia.
