As global warming becomes more and more obvious, energy saving and emission reduction become more and more important. And in energy saving and emission reduction, windows actually play a key role: strong solar radiation generated by the hot sun in summer will increase the indoor temperature through the window glass, and indoor heat in winter can be released to the outside world through the window glass. The energy lost through windows can amount to half of a building's energy consumption. So many scientists are focusing on windows.

Haier enters the UK market understanding the importance of building relationships with the people that matter with real value propositions of high performance, market leading product training and comprehensive aftersales service support. For many installers attending the Show, it will be the first time they have seen the Haier range in the UK. Haier have large operations across the world and the journey that Haier HVAC has been on in Europe has been a successful one with substantial growth in key European markets such as Italy and Spain. Whilst new to the UK market, Haier brings a new and competitive approach to the HVAC market. A full portfolio creating a unique one brand, one solution for residential and commercial applications. We are very excited to welcome UK installers onto our dynamic and interactive stand to see the portfolio, take part in the Haier Challenge and have a drink with the Haier staff and our partners.

From June 12th to July 14th, the JAKARTA FAIR 2024, the largest consumer goods exhibition in Southeast Asia, is held at JIExpo Kemayoran, Jakarta, Indonesia, gathering numerous local and international brands. Gree is participating in this Fair, which is of great significance for establishing Gree brand image and promoting local market sales in Southeast Asia. On the first day of the Fair, the exhibition is crowed with numerous visitors.

In recent years, increasing global warming has caused frequent heat waves, bringing continuous high temperatures and high humidity, and the resulting impairment of human cognitive performance has become a growing concern in society. In order to explore the response pattern of human cognitive performance under humid-heat exposure, five types of continuous cognitive tests were conducted under humid-heat environmental exposure at temperatures of 32, 35, 38, and 41 ℃, respectively, and relative humidity of 70%, during which the characteristics of the cognitive test results (mean reaction time and mean correctness) of 14 male subjects were observed in response to the environmental temperature. The cognitive tests were uninterrupted during the exposure until the subjects refused to continue the experiment. The results showed that: the subjects' mean reaction time to process the cognitive task increased with increasing ambient temperature, and the mean correct rate decreased with increasing ambient temperature; during the exposure time, the mean reaction time increased sequentially in the first 3 tests and then decreased in the 4th and 5th tests; whereas, the mean correct rate continued to decrease in the first 3 tests and increased rapidly in the 4th and 5th tests; furthermore, it was observed that the relative cognitive In addition, it was observed that relative cognitive performance decreased with increasing ambient temperature, but the rate of decrease slowed down when the ambient temperature was higher than 35 ℃. Relative cognitive performance showed an approximate U-shape distribution over the exposure time, and the higher the ambient temperature, the more the lowest point of the U-shape curve corresponded to the earlier time. This study provides a potential solution for the assessment of cognitive performance in hot and humid environments.

In China's public buildings, the energy consumption of refrigeration plant rooms occupies the vast majority of the energy consumption of air conditioning and ventilation systems, with its energy consumption accounting for about 70%. Seven ministries and commissions, including the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, and the Ministry of Finance, jointly issued the Green and Efficient Refrigeration Action Program on June 13, 2019, which explicitly requires that by 2030, the energy efficiency of refrigeration in large-scale public buildings will be improved by 30%, the overall level of energy efficiency in refrigeration will be improved by more than 25%, the market share of green and efficient refrigeration products will be increased by more than 40%, and an annual power saving of 400 billion In October 2021, in order to realize the "double carbon" goal, China has successively issued relevant working opinions and action programs on carbon peak and carbon neutrality, and clearly defined the development goal of energy transformation. Therefore, the efficient design of refrigeration plant rooms not only meets China's national conditions and policies, but also reduces energy consumption and promotes the high-quality development of related industries and green low-carbon transformation.
