During the middle and later stages of condensate gas field development, the flow rate and pressure of the light hydrocarbon recovery system gradually decrease, and there is a certain deviation between the design parameters and the actual operation parameters of the equipment, resulting in a...

The European Union, through the Energy Performance of Buildings Directive and the Energy Efficiency Directive, has been establishing requirements and expectations regarding energy savings and efficiency in buildings. The objective of this study is to explore energy rehabilitation solutions for...

In this study, a new application of a Tesla turbine (TT) is presented in which a TT is introduced as a promising solution to enhance the energy efficiency of refrigeration cycles. For this special purpose, a TT is represented as a regenerative system that minimizes the wasted energy without...

Buildings Energy Certification System (SCE) was implemented in Portugal through the publication of the Decree-Law 78/2006 and due to the adjustment of national legislation imposed by EPBD 2002. Thus, since January 1, 2009 all residential and service buildings, new, refurbished or existing must...

A new ammonia-water power cycle (AWPC) basing on Kalina cycle is presented in this paper, which supply an effective way for low-moderate temperature geothermal power in China. The thermodynamic models of AWPC are established considering of the ratio of power generation as the optimization...

The use of graphene nanolubricant to enhance the performance of eco-friendly refrigerant (R600a) in a vapour compression system was investigated. The graphene nanoparticles were dispersed in the base lubricant and prepared for three different samples of graphene nanolubricant concentration of...

The actual state of electricity consumption characteristics in the residential sector in Thailand was presented. They were an essential information for the total energy usage estimation. They were used for investigating the feasibility of energy conservation. A questionnaire interview survey of...

Thailand's textile industry is the traditional industrial sector which shows the continuous increase in energy consumption and Energy Intensity (EI) index, primarily on electrical and thermal energy. This paper aims to track the implementation of energy conservation measures through the textile...

Two Identical six doors walk-in coolers are installed with the fixed speed compressor and the digital scroll compressor. Both compressors have almost the same cooling capacity of 8 kW at the evaporating temperature of -6.7 °C and the ambient temperature of 32 °C. The heating loads from the...

The objective of this wok was to develop the high energy performance standards (HEPS) for oil-injected air-cooled screw air compressors in Thailand. Based on the data from the Customs Department in 2018, it was found that Thailand imported a great number of air compressors with total value of...
