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...
Kind Code: A1 Abstract: Determining the condition of hair comprising tensioning a partial section of a hair sample until the sample tears and determining the force required to tear the hair, determining the length by which the partial section of the hair sample is elongated at the point of tea...
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 ...
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 ...
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 ...
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...
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 ...
