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...
European homes and apartments are generally smaller, making them easier to heat and cool. The materials used to build them stem from centuries of construction practices that were meant to cool and heat homes before there was air conditioning and indoor heating. This helps to keep the down energy...
Air-conditioning systemCooling energySensible and latent loadsAir-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 ...

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 ...
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 ...
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 ...
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 ...
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 ...
