Comparative study of correlations for heat transfer coefficient at full evaporation of refrigerantR22 in tubes of air coolers is made. The low accuracy of the well-known equations is shown. Briefdescription of the six generalized correlations for local heat transfer coefficients is given. An error of useturbulent regime equation for calculating Nusselt number at Reynolds numbers Re<10000 in threemethods is spotted. It is recommended in practice use four methods of foreign authors.

Citrus fruit rank first in the world with respect to production among fruits. They are grown commercially in more than 50 countries around the world. Orange juice is dominant among the various citrus juices. Initial product quality is dependent on the conditions of processing and variables associated with the biochemistry of the fruit. One of the most popular orange varieties for juice production is «Valencia», therefore biological characteristics of orange juice variety «Valencia» was studied with time. The orange juice was tested during two month. Studies have carried out at the Greece “BIOFRESH” laboratory, Sparta. In orange juice like pulp, sugars, organic acids, ratio and essential oil are observed during two month.
The study results show that on May orange NFC «Valencia» has minimum sugars - 8.59 ˚Brix and on June orange NFC «Valencia» has 12,28 ˚Brix. The acid decreased from 1,03g 100g-1 on May to 0,79g 100g-1 on June. On May, orange juice has 10,58 Ratio, but on June «Valencia» orange juice has maximum Ratio 13,86 The pulp parameter was stable during both months. The essential oil concentration in orange juice was from 272 ppm to 340 ppm.

There is justified the urgency of the development of fish preserves with antihypertensiveproperties from the Baltic sprat by replacing table salt for prophylactic table salt in the recipe with theaddition of antihypertensive herb extracts. There are determined the amounts of vitamin C and flavonoidsin the extracts causing antioxidant and preservative effects respectively. There are shown taste and aromaprofilograms of the developed preserves. There are obtained the indicators of nutritional and biologicalvalues of experimental of preserves samples (calories, protein, fat, carbohydrates), data on the content ofvitamins, micro and macronutrients, the amino acid composition of proteins. There are recommendationson the use of data preserves.
