Performance Investigation of the Influence of Ambient Temperature on a 1.5HP Air – Conditioner

Abstract

The influence of ambient temperature on the performance on a 1.5HP Air – Conditioner that is connected to office of size 6830mmx248mmm has been investigated experimentally. The data collection was conducted for thirteen (13) working days for every degree interval as it is well enunciated in the dashboard of the air – conditioner by the manufacturer: LG Nig. LTD. Periodically, the collection of data was performed as follows: morning period: 7:00am – 9:00am; afternoon period: 12:00pm – 2:00pm and evening period: 4:00pm – 6:00pm respectively and it commences with the least temperature 160C and ends with 250C. The results revealed that as the ambient temperature increases to 38oC, the cooling temperature increases to 250C while the time of cooling during morning, afternoon and evening periods increases to 24mins, 24mins and, 22.5mins respectively. It is recommended that keeping the air – conditioner at a cooling temperature of 220C is advisable during usage.
