Currently, energy efficiency is the most important for low-temperature technology (TNT). The high energy efficiency of low-temperature technology is an element of environmental safety. One of the main development of Kaltra microchannel coils is:
- the use of new, more efficient heat exchangers;
- reducing the size and weight of the equipment used;
- reduction of refrigerant charge.
These points can be achieved using microchannel heat exchangers (TA) as condensers. It should be borne in mind that the share of domestic refrigeration equipment in the country’s market is extremely small, and the country’s strategic and economic interests require building up scientific and engineering potential.
The Kaltra company, as one of the measures for import substitution, launches the production of new compact microchannel coils for industrial systems. In order to determine the nominal technical characteristics of the product line being created, an industrial test facility was created at the company’s site to study prototypes and serial samples of compact heat exchangers.
Thus, the Kaltra study of the influence of electric, magnetic fields, and other methods of influencing the process of mass transfer in the gas-liquid layer for the purpose of intensification is an urgent scientific task. The choice of a method for controlling the emerging electrohydraulic effects in the phase contact zone is a promising aspect of solving the problem of controlling heat and mass transfer processes in thermal reactors with a submersible combustion apparatus.
The most widespread are vibration-frequency measuring transducers, in which the resonator measuring sensor is mechanically connected to the investigated oscillating medium. The main disadvantage of such measuring instruments is the presence of nonlinearity, which complicates the choice of the type of resonator. The proposed self-oscillating system of vibration-frequency sensors with changing nature of nonlinearity greatly simplifies the development of resonator sensors.
