Comparing air conditioning quotations can be confusing. Simply choosing the quotation with the cheapest ‘bottom line’ is often a recipe for disaster. We have created this independent guide in the hope that it will help you to quickly assess the various quotations you have obtained and determine ...
Air-conditioning (AC) system is typically used to remove the sensible and latent heat loads in buildings. It provides cool and dehumidified air to meet the occupants comfort and good indoor air quality (IAQ). Improper design and analysis of AC process resulted in high cooling energy and ...
For clients where budgets are limited, understand that an 8kW inverter cannot power a 10kW air conditioner unit. Even if the unit only draws 3kW during normal operation, if it has a 10kW rating then at some point it will draw 10kW of power (such as when defrosting the indoor unit during ...
Assuming both uniform and non-uniform cooling air flow rates, solutions based on single and double (parallel or series) hoods were characterized in terms of arrangement, control criteria and performance. Finally, a comparison analysis was carried out based on plant complexities and benefits of ...
PROBLEM TO BE SOLVED: To estimate objectively the quantity of power consumed by one's own air conditioning apparatus from the results of comparative estimates of the air conditioning apparatus of a specified user and other air conditioning apparatuses and to investigate the cause of an increase at...
Packaged ammonia chillers (PACs) are similar to R- 134a chillers. Both are factory-assembled refrigeration systems that use conventional refrigeration drivelines. PACs are becoming increasingly popular for non-air-conditioning applications. In this paper, the author analyzes ammonia's competitiveness in ...

The flow of these is generally thought to be dominated by viscous ...
Household-level information on central air conditioning (cenAC) and room air conditioning (rmAC) air conditioning and cold-weather thermal comfort are often missing from publicly available housing databases hindering research and action on climate adaptation and air pollution exposure reduction. We ...

The system has outside and inside air temperature sensors (2, 3) sending information about outside and inside air temperatures to a computer (4). The computer compares the information with respect to a set point (1) that is activated by pushing a push button (6). The set point is pre...
