“…In IEC devices, the primary or product air passes through the dry channels of heat exchanger (HX) and the secondary or working air travels through the wet channels. The wet side absorbs heat from the dry J o u r n a l P r e -p r o o f side by evaporating water, thus cooling the dry side, while the water latent heat of vaporization is released to the air in the wet channel [34]. The primary air temperature on the dry channels decreases sensibly from point 1 to 2, as shown in Fig.…”

“…It was determined that the value of working to main air-flow ratio has a significant impact on the cooling performance of considered air coolers. Shahzad et al (2019) proposed an improved indirect evaporative cooler system for sensible cooling that can be combined with dehumidification processes to achieve sustainable cooling goals. The outlet air of the dry channel is injected at different points into wet channel.…”

The dew point evaporative air conditioning system has gradually become an attractive research area in recent years because of its low energy consumption and environmental friendly advantage. How to improve the system efficiency is the focus of current research. This paper presents the theoretical performance of the dew point evaporation model with or without perforations. The heat and mass transfer model of the dew point evaporative cooling system was established and solved. It was found that the optimal supply air ratio was 0.7-0.8 and the value of the channel height was 4mm-5mm according to the evaluation parameter of the cooling capacity. Compared with other parameters, the supply air ratio has a more significant effect on the performance of the perforated cooling system. Single perforation has the best cooling system performance with supply air ratio of 0.5-0.7. Two perforations is the best for supply air ratio 0.3-0.4, while three perforations is more appropriate when supply air ratio is 0.2.

“…Oh et al [25] proposed a detailed mathematical model to analyze the counter-flow indirect evaporative cooler with two different purge ratios. Furthermore, Shahzad et al [26] proposed an improved indirect evaporative cooler system for sensible cooling that can be combined with the dehumidification processes in order to achieve sustainable cooling goals. Evaporative cooling is generally divided into two types: (1) indirect evaporative cooling (IEC), and (2) direct evaporative cooling (DEC).…”

Sustainability of Evaporative Cooling System for Environment Control for Preservation of Unearthed Historical Sites within Archaeological Museums in China

et al. 2020

Archaeological museums are usually constructed at the location where historical relic sites are unearthed and are often characterized by large-space building layouts and high energy consumption for the environmental control. However, the traditional strategies for environmental control are limited in protecting the unearthed relics from desiccation cracking and salt concentration. In this study, an environmental control strategy of evaporative cooling system is proposed as a solution to develop a sustainable preservation environment to maintain the condition of the ancient relics at a state of moist saturation. Afterwards, a verification of sustainability and climate suitability analysis of the proposed system were conducted. The results indicate that (1) the evaporative cooling system can fulfil the high humidity preservation environment requirements for the unearthed historical relic sites with a low energy consumption; and (2) the potential use of the evaporative cooling systems is significant in Xi’an and Chengdu (i.e., being 62% and 75%, respectively), and not in Lanzhou and Urumqi. As a conclusion, the proposed strategy provides a sustainable protocol for the preservation of unearthed historical relic sites in archaeological museum.
