Abstract

In this paper, experiments were conducted to study the effects of adjusting several factors on five types refrigerated display cases of food retail stores, including indoor air temperature and relative humidity, the preset temperature of frozen display cases. The result shows that the display cases' cooling load increased with increasing the temperature and relative humidity of the indoor air environment. Furthermore, when specific enthalpy of indoor air environment increases from 27 to 72 kJ/kg, the electric power consumption of the refrigeration system increases roughly, and the COP remained steady condition. Furthermore, frozen multi-deck display cases affected vulnerably in variations of indoor air temperature and relative humidity. With the preset temperature increased by 3?, the temperature difference between inner and out of display cases and frost formation on surface of evaporator were affected directly.
