FIELD: heat and power engineering, possible use in steam compression heat pump plants of heat provision systems of residential buildings, public buildings, industrial buildings and technological equipment of industrial and agricultural enterprises.
SUBSTANCE: method includes filling receiver with water. Internal hollow of heat-pump plant during filling is connected to surrounding air, and water is heated to boiling. Water may be heated in a separate vessel and then injected into the receiver. It is possible to vacuumized internal hollow of heat pump plant after filling of receiver with water up to pressure which corresponds to pressure of saturated fumes of water at temperature of air surrounding the heat pump plant during evacuation.
EFFECT: increased efficiency of output of steam compression heat pump plant filled with water due to removal of water-soluble gases from its circulation contour.
