1. EVALUATING HOW THE TEMPERATURE CHANGES IN A SUNKEN SOLAR GREENHOUSE
ABSTRACT An increasing amount of sunlight is available to sunken greenhouses located in northern China, but it remains unclear how the indoor temperature changes at different heights and at the north and south ends of the structure. To study how the temperature in a single indoor section, at multiple points, varies in a sunken solar greenhouse, 10 measuremen

2. HYBRID SYSTEM SIMULATION TO SUPPLY HEATED AIR TO A SOLAR FOOD DRYER
ABSTRACT The intermittence of solar radiation, due to continuous rainy or cloudy days, is a limitation of simple and small solar dryers. These conditions often make them impossible to use. By including storage systems (thermal accumulation) and/or auxiliary energy sources, drying processes or dehydration can be conducted continuously, even during periods of

6. HYBRID SOLAR HEAT PUMP SYSTEM FOR WATER HEATING
ABSTRACT A comparative test of water heating between the hybrid system - solar collector with heat pump - and a system with conventional supplementary heating - with high electric power - was performed. For this, a small capacity heat pump was installed, which was later installed together with a solar heating system, composed of a 250 L thermal reservoir and

7. Development of paints with infrared radiation reflective properties
Abstract Large buildings situated in hot regions of the Globe need to be agreeable to their residents. Air conditioning is extensively used to make these buildings comfortable, with consequent energy consumption. Absorption of solar visible and infrared radiations are responsible for heating objects on the surface of the Earth, including hou

12. APROVEITAMENTO DE FONTES ALTERNATIVAS PARA REDUÇÃO DO CONSUMO DE ENERGIA ELÉTRICA E REFLEXOS NOS SEUS CUSTOS / UTILIZATION OF ALTERNATIVE SOURCES FOR REDUCING POWER CONSUMPTION AND ITS CONSEQUENCES IN COSTS
Residential consumption accounts for around one third of total energy consumed in Brazil. The electric shower is the main component of this consumption, along with air conditioning. Hence, much research has been conducted in order to reduce the consumption of this sector and the use of alternative energy sources. Among these include mainly solar and geotherm
