4. Influence of ground heat source parameters and consumer on characteristics of geothermal heat pump system

Author

Filatov, S. A. and Volodin, V. I.

Subjects
теплоснабжение, теплонасосные системы, теплота грунта
Abstract

Features of heat supply system based on the use of ground are investigated with the help of the method of numerical simulation. The variables are the parameters characterizing the heat source and the consumer: the average temperature ofthe soil, the area and the radiative properties of the surface heating panels, air temperature of heated space. It was found that the maximum energy efficiency of the system is achieved by using a low-temperature floor heating system.

Abstract

The article makes a theoretical substantiation of regional dehydration in the treatment of the posttraumatic swellings in bone fractures of the extremities. The state of regional hemodynamics in 226 patients with the affections of bones and vessels of the extremities was studied using clinical, functional and angiographical methods. The authors make a conclusion concerning the efficiency of the proposed method of treatment for posttraumatic swellings of the extremities, which is based on the rapid enhancing of the mole-factor in the blood plasma in order to recover optimal conditions for the exchange process and microcirculation. This method of regional dehydration is proposed by the authors as an alternative to the fasciotomy which is based on mechanical influence upon extravasal squeezing of vessels.

Abstract

A procedure for analyzing gaseous products resulting from metabolic processes of microorganisms has been developed. The procedure allows a distinct separation of gaseous products (H2, O2, N2, CO2, H2O, etc). The relative error ranges from 3.4 to 2.9% depending on the concentration of the gas in the volume tested.

Abstract

Possible errors and complications are analyzed basing on the experience with microsurgical autotransplantation of 87 tissue complexes fulfilled in 81 patients with traumas. Various complications were established in 25 out of 82 patients (30.4%). Acute disturbance of the transplant blood circulation was noted in 17.2%. Reoperations on the vessels reduced the incidence of failures to 8% of all the transplanted complexes of tissues.
