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 ...
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 ...
Both the Aquamar and the Grille are open to the outside and have no air conditioning that we could see. On cold days, they have heaters but not even fans for hot days. On our last sea day before we got to Miami, the temperature was in the high eighties/low nineties and the ...
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...
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 ...
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 ...
Air-conditioning was eagerly adopted by Qataris after the nationalisation of their oil and gas reserves soon made them some of the wealthiest people in the world. In recent years, however, local officials have started to consider the social and environmental benefits of other ways of living ...
Both synthetic lubricants are widely used in air-conditioning compressors and have been optimized for use with hydrofluorocarbon (HFC) refrigerants. However, it is still not clear which lubricant is more suitable for use in compressors operating with CO2 as a refrigerant. This study compares the ...
Refrigerant leakage determining method for air conditioning system, involves comparing measured high pressure with reference high pressure, and determining lack of refrigerant amount from difference between measured and reference pressuresThe method involves implementing sucking at a suction side of a ...
A dew point of air at the evaporator is determined, where the dew point is the pre-evaporator-dew point or the evaporator temperature. The dew point of air at the evaporator is compared with the temperature of a windscreen and the motor vehicle air conditioning system is regulated so that ...
