EFFECTIVE WATER WITH GRUNDFOS

NEW MASTERPIECE FROM MITSUBISHI ELECTRIC

This year the majority of the world’s leading manufacturers to bring to market for new air conditioners , eco friendly , refrigerant R32. So , Daikin this spring released refrigerant R32 version of its top-end air conditioner – Ururu Sarara ( air conditioner Daikin Ururu Sarara R32 is already sold in Europe and managed to win the prestigious Red Dot 2013 ) . The world’s largest manufacturer of climatic equipment company Gree, began selling household split systems not only refrigerant R32, but also not afraid to market a version of the refrigerant R290 ( propane) . Conditioners on their R32 released of Fujitsu General, Hitachi and Panasonic ( sold only in the Japanese market ) . Even the company of “second tier” like Midea and Haier, have kept up with the leaders and summer in China began test delivery systems for R32.

What are the advantages of refrigerant R32? First of all, in its ecology – its impact on the ozone layer and global warming is set to almost zero . The new refrigerant is fully consistent with very strict standards which will be applied in the European Union since 2018. Hence, a natural desire to advance leaders break in new technologies is still at a fairly expensive models and 2018 massively introduce their models budget price range. Besides, the new refrigerant a huge potential for creating high air conditioners. Below in Table 1 , we present the energy efficiency of air conditioners on the coefficients R32 ( comparison models 2.5 kW ) . Continue reading

WALL AIR HANDLING ventilation units with heat recovery MITSUBISHI ELECTRIC LOSSNAY VL-100EU5-E

According to the normative literature containing sanitary requirements for residential buildings , they should be provided with ventilation natural impulse . These are the most well-known all exhaust grilles in the kitchen, bathrooms and bathroom. A compensation exhaust air usually provide by entering the room apartment outside air through gaps in window openings , through open windows or skylights . There is such a thing as the outside air infiltration – the influx of outside air seeping through cracks external protections under the influence of wind and gravity. The beauty of this solution is that the optimal size of the window openings leaks and power headroom heating system we get a natural flow of fresh air , rich in oxygen , without additional construction and money.

In the calculations of ventilation in residential buildings sanitary norm of fresh air for each person in the room is usually considered 60 m3 / h per person or 3 m3 per 1 m2 of living space . Continue reading

AIR CURTAINS FRICO: NEW , UNIVERSAL , SMART

Two years ago the management of the concern Systemair was decided to consolidate the production of all heating equipment under the brand Frico. On the one hand, it significantly expanded the possibilities, but on the other – significantly increased the responsibility for the possible failure of the local , including Ukrainian , markets.

At the same time the company’s strong growth came through acquisitions and air curtains manufacturers (Gelu, Shearflow, Tekadoor) in Europe . Partially their products poured into the main lineup, expanding its capabilities, partly dubbed the already existing model curtains Frico.

Thus, by the beginning of 2012 under the brand Frico produces more than 390 different air curtains . They were made in different countries, in different companies , with different technologies and different hardware components .

This circumstance prompted Systemair engineers to develop a new generation of air curtains that would connect a results of the most recent studies with new technological possibilities .

According to specialists, the diversity of the manufactured equipment could be without prejudice to the consumer to replace 150 models , making them the most versatile. Primarily developed product series PA3500 and PA4200, designed to replace the hangings series AS300/400 , AD300/400 and AG/AGV4000. Horizontal model with appropriate accessories can be connected in a continuous line , installed vertically and join column or placed in a suspended ceiling . Dimensions curtains from 1 to 3 m in increments of 0.5 m equipment available in versions without heating (A) , with electrical ( E) and hot water coolant with different parameters (WH, WL, WLL).

EFFECTIVE WATER WITH GRUNDFOS – the right way to conserve resources

As is known , Ukraine not apply to countries with efficient use of natural resources . However, over the years , this problem becomes more acute. Significant place in wildlife occupy the rational use of water resources is .

Today, the only tool stimulating the end user to save resources (water , energy ) are tariffs, which significantly outpaces growth official inflation. But do not forget about the water suppliers , who also have to pay the state at the relevant rates for use of water resources . When water is taken and reset rates above the established limits defined by the state, increased significantly.

Therefore, the main task facing the water distribution system is to ensure a stable water supply , water management , which can be very scarce , detection and elimination of pipe rupture , leakage reduction and keeping operating costs as low as possible . Here one of the most effective solutions is to upgrade water systems engineering , which involves the use of high-tech pumping equipment together with modern automated control systems .
