Have you ever noticed the tomatoes, potatoes, chili peppers, etc. that you eat on a regular basis, in fact, there may be “going” to space. All along, the world has not stopped the footsteps of space breeding experiments, hundreds of plant seeds have been sent to the International Space Station for cultivation. Among them, chili peppers are one of the most popular plants. Why are chili peppers so popular? Is there any radiation in food grown in space? Is it safe? It all starts with providing fresh food for the astronauts who stay in the space station for a long time.

Multi-split air conditioner, also known as variable refrigerant flow multi-split air conditioning system, consists of an outdoor unit connected to a number of direct evaporative indoor units of different or the same type and capacity, constituting a set of single cooling/heating cycle air conditioning system, also referred to as VRV or VRF.

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.
