Definitions

  • the invention relates to a processmethod for cooling and/or heating, by means of an electrically driven appliance, comprising one or several compressors, one or several evaporators and one or several condensors.
  • a system which consists of one or several compressors, evaporators with ventilators and/or pumps and one or several condensors with ventilators and/or pumps being provided with frequency transforming devices which adjust the speed of rotation,said frequency transforming devices being controlled by a microprocessor.
  • FIG 1 a plant as designed for the process method according to the invention is shown schematically, wherein the compressors (1), the evaporators-ventilators (2) or - pumps (3) and the condensor valves (4) or - pumps (5) are indicated, provided with frequency transforming devices (6) operating as adjusting instruments for the velocity of rotation and being controlled by the microprocessor (7).
  • piston compressors (1) are used, preferably of the open or indirectly driven type.
  • the electromotor (8) of compressor (1) is adjusted by the frequency transforming appliance operating as an adjustment device (6).
  • the control is effected by measurement of the temperature (9) and/or of pressure (10).
  • the oil pump is built in the compressor,but in the plant of the invention this is dismantled and replaced by a connector.
  • an externally situated hermetically closed oil pump (11) is linked with its own electrical drive which maintains an even pressure of lubricant oil at varying speeds of rotation which are effected by the compressor in this process method.
  • the speed of the evaporator-ventilators and of the condensor-ventilators and/or the pumps is also adjusted by the adjusting device (6).
  • the control takes place by temperature measurement (9) and/or pressure measurement (10).
  • the plant is provided with a microprocessor control (7) into which the following measured data from the system are supplied:
  • the measured data supplied are compared and checked.
  • the most efficient values of the energy measurements are being determined.
  • one or several evaporator units (14) are connected, operating within a defined range of evaporation temperature, and one or several condensor units (16), operating within a defined range of condensation temperature. If several units are used within the same temperature range J the capacity will be determined by the unit requiring the largest temperature range.
  • the other units are being reduced by means of an electronically controlled valve (12) adjusting the flow of gas and/or liquid.
  • the speed of rotation of the ventilators is also adjusted.
  • Said nominal charge will be considerably lower than the peak charge, resulting in diminishing losses,on an average occurring by motion of parts (pistons, gearing etc.) and by resistance (of gas and liquid in conduit pipes, valves, stop-cocks etc.)
  • the flow velocity rates in the system can be increased.during a short period, in order to maintain a fair flow of oil.
  • the switching on and off of illumination and for example the control of movement of coverings during the night can be accomodated in the form of adaptation.
  • Repair of interferences can be carried out in a fast manner, because of the central recording system and trouble signalling so that damage will remain restricted.
  • the control and adjustment of the condensor - ventilator (4) makes the use of an extra ventilator for room conditioning directly condensor superfluous.
  • the total system renders a very considerable saving of energy.
  • the system can find a broad field of applications, such as cooling of cooling-storage-cells, closed and open refrigerators in supermarkets, plants for alimentary technology, storage possibilities in harbours, transport and haulage, refrigerated transport, heating of dwellings and living rooms, offices, use of heat pumps etc.
