NOMINAL 9,000-BTU/HR, COMPACT, HORIZONTAL, AIR-CONDITIONING UNITS

Abstract

Tests were conducted to evaluate and improve the prototype development of compact, horizontal 9,000-Btu/hr air-conditioning units. Functional tests included cooling capacity, heating capacity, cooling operation at return-air temperatures as high as 150F, cooling operation at outdoor ambient air temperatures as low as 0F, and heating operation with inside ambient temperature as low as -55F. Tests were made to determine electrical characteristics under normal as well as conditions of voltage and frequency different from nameplate values. Environmental testing included the duress of shock, vibration, and adverse weather conditions as well as noise and radio frequency interference. Improvements were made and the resulting unit has simple operation, adequate capacity, and is sufficiently durable to operate in world-wide climates.
