Automated heat pump unit (ATNU) provides:
- heating and automatic maintenance of the set temperature in the room;
- year-round hot water supply;
- cooling of utility rooms (pantries, vegetable stores);
- seasonal (spring, autumn) heating of greenhouses.
ATNU includes a hermetic refrigeration compressor, heat exchangers, an automatic unit control unit, a peak electric drive, and a hot water storage tank.
The use of the installation makes it possible to reduce energy costs for the operation of buildings by 60-70% compared to traditional methods of heating and air conditioning. Technical characteristics of such installations are given in table 8.4.

The principle of operation of the heat pump is the cooling of antifreeze, which is supplied from the well and has a temperature of +8 degrees, due to the temperature of the surface layers of the earth.
A well with a depth of 36-38 meters is drilled for one pump, the diameter of the well is 160-168 mm.

Alcohol content of warm beer
07.05.2024
Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>
Major risk factor for gambling addiction
07.05.2024
Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>
Traffic noise delays the growth of chicks
06.05.2024
The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>
| Random news from the Archive radio controlled genes
31.05.2017
It is known that many animals, such as birds, bees, lobsters, newts and others, can sense the relatively weak magnetic field of the Earth and navigate in space with its help. Such abilities are “hardwired” into the genetic code of these animals, and recently researchers from Baltimore managed to find the corresponding sequence in the genome of one fish, the glass catfish (glass catfish, Kryptopterus bicirrhis), isolate it and introduce this sequence into the genome of nerve cells in the brain of an experimental rodent. After such a genetic modification, the rodent's brain became sensitive to electromagnetic waves, and a similar technology can be used in the future for non-destructive monitoring of the activity of nerve cells and heart tissue cells, for example.
Scientists have previously been able to identify the genes responsible for "magnetic perception" in pigeons and some types of bacteria. Most of these genes are part of very complex biological mechanisms, and the gene removed from the glass catfish is unique in that it works completely on its own and is not associated with any other complex biochemical complexes.
The scientists searched for the magnetic gene by inserting segments of the catfish genome into the genome of frog egg cells. Observations of the reaction of modified eggs to a magnetic field allowed scientists to identify a gene called the electromagnetic perceptive gene (EPG). How exactly proteins produced by the EPG gene sense magnetic fields is still a mystery to scientists, which they will have to unravel in the near future. But the effect of these proteins has been known for a long time, this protein fills the cell with calcium ions, which leads to the "activation" of a neuron or contraction of a muscle tissue cell, for example.
The researchers believe their discovery opens the door to wireless biological pacemakers and brain-computer interfaces that use radio signals to communicate with nerve cells. In addition, the introduction of the EPG gene can be what gives animals and even humans another kind of sense - a sense of magnetic and electromagnetic perception, similar to that possessed by numerous superheroes from various science fiction films and works.
