Refrigerant charge faults have a great adverse effect on the performance of heat pumps and must therefore be detected and diagnosed early in real time. In this study, the effect of refrigerant charge faults on a water-to-water heat pump is experimentally ... see more

In the present study, we have developed an optimal heat supply algorithm which minimizes the heat loss through the distribution pipe line in a group energy apartment. Heating load variation of a group energy apartment building according to the outdoor air... see more

Increasing the temperature of inlet water is one way to increase solar distillation efficiency. Heat recovery using double glazing is a more straightforward way to raise the temperature of inlet water. In previous studies, the incoming water temperature w... see more

The use of electrical energy for the cooling system reaches 47% - 65% of the total electrical energy used in buildings. Therefore, in order to reduce energy use, it is necessary to evaluate, evaluate and recommend in the process of increasing the energy e... see more

AbstractMeasurements of water temperature, salinity, pH, dissolved oxygen, secchi disk depth, turbidity and total suspended solids were taken monthly in the Knysna estuary between 1991 and 1994. Measurements of turbidity and total suspended solids of wate... see more

A mathematical  model  for the  primary  chemical  process  occurring  in 1J/pulse electrical discharge  in water  has been developed .The discharge  channel  is divided  into  two zones: Th... see more

The air conditioning machine commonly used is air conditioning system with a vapor compression cycle. The use of air conditioning machines consumes more electrical energy than other household appliances. In this study, the addition of the water mist metho... see more

One of the promising ways to reduce operating losses in main gas pipelines is pre-cooling of compressed gas using heat-using absorption water-ammonia refrigeration machines (AWRM), which utilize the waste heat of the exhaust products of the combustion of ... see more
