The author's abstract
Actuality
Operational properties RT are defined by their heat power parameters (HPP), such as ability to support simultaneously in
various branches demanded temperatures, a current consumption, etc. On the
same parameters is defined also a parameter of power efficiency RT - the
class энергопотребления RT. от
qualities of tests in many respects depends quality both
developed models RT, and finished goods. Therefore definition and control
HPP RT (further heat power tests) is carried out at the enterprises "
Groups the NORD" at all stages of creation and manufacture RT. For this
purpose the automated systems, such as are created and used various to
destination, to characteristics and structure:
- The automated system of tests of refrigerating devices (ASTRD) - for carrying out of acceptance
tests (CAT) all RT, acting from assembly conveyors of manufacture of
assembly of refrigerators;
- Station of selective control HPP RT (SSC) - for carrying out of
selective quality assurance of carrying out CAT by automated specified
definition HPP RT, past CAT;
- The automated system for heat power tests RT (ASHPT RT) - for carrying out of research and all kinds of control tests RT
(Joint-Stock Company " DIRТ").
Within the limits of the works spent by joint-stock company "
NORD" on transition on hladon which does not destroy
an ozone layer, modernization of test base for its
finishing up to a level of requirements of the world standards, improvement
of quality and efficiency of carrying out of tests is spent also. It also
defines a urgency of the given work.
The purpose of work
The purpose of work is
development and research of structure of system of heat power tests of
refrigerating technics and optimization of technology of the control of heat
power parameters RT in conditions of assembly manufacture of Joint-Stock
Company " NORD" for improvement of quality and efficiency of
carrying out of acceptance tests RT.
Problems of work
Realization of an
object in view provides the decision of such problems:
- The analysis of heat
power processes in RT;
- The analysis of
system HPP RT and requirements to them;
- Definition of
problems of measurement and control HPP over various stages of creation and
manufacture RT;
- The analysis of
methods and means for definition HPP RT;
- Development of
mathematical model of processes in RT during CAT
- Research of features
of is functional-structural organization ASTRD;
- Research of
technology of the control of heat power parameters RT in conditions of
assembly manufacture of Joint-Stock Company " NORD";
- Research of
dependences of heat power parameters from an ambient temperature;
- Definition of
optimum values of criteria of decision-making on results of tests and
duration of tests from an ambient temperature;
- Development of a
microprocessor test column for ASTRD.
Methods of research
At performance of
researches and development are used:
- Methods of the is
functional-structural analysis and structural synthesis of complex systems;
- Statistical methods
of processing of experimental data;
- Methods of the
theory of measurements;
- Methods of designing
of microprocessor systems.
Prospective scientific novelty
Developed mathematical model
Developed of algorithm
carrying out CAT for model RT.
Prospective practical value
Application of results
of researches will provide improvement of quality and efficiency CAT RT
(reduction of duration of tests, increase of a degree of automation of
carrying out CAT, reduction of the miss of marriage).
The developed test
column for ASTRD will provide increase of accuracy at carrying out of heat
power measurements.
The basic results of work
Expected results of
the executed researches and development:
- On the basis of the
analysis of methods, means and problems of definition HPP features of is
functional-structural organization ASTRD for carrying out CAT RT in
conditions of Joint-Stock Company " NORD" are investigated;
- The mathematical
model of processes in RT during CAT is received;
- Optimum values of
criteria of decision-making on results of tests and duration of tests from
an ambient temperature for one of models RT are certain;
- The technology of
the control of heat power parameters RT is advanced at carrying out CAT in
conditions of Joint-Stock Company " NORD";
- The scheme of a
microprocessor test column is developed.
Application of the received results will provide expansion of functionalities of a test complex, improvement of quality and degrees of automation of tests.
