摘要： The invention relates to a method for controlling the heat pump, and in particular to a method for controlling the expansion valve for adjusting the superheating of the working medium, wherein the dew point (ps) is determined by means of a unidirectional neural network; a method for controlling the process of thawing the exchanger of the lower heat source, wherein based on the measurement and analysis of the temperature difference upstream and downstream of the exchanger of the lower source of the heat pump, of air humidity and instantaneous power of the compressor, the value of energy obtained from the lower source of the heat pump in a characteristic period of time is determined, and this value is compared to adequate historical data, wherein the compressor in the thawing mode is activated only when the current value of energy is lower than the set percentage of the energy value taken from historical data; and a method for controlling the switching on of the compressor, wherein coefficient of heat demand Qh of the heated building is dynamically determined based on the difference between the set and current values of the heating circuit supply and based on measurements of temperature and humidity of outside air. The method according to the invention allows an increase in the efficiency of the heat pump through accurate adjustment of the superheating of the cooling medium upstream of the evaporator, optimisation of the operation periods of the compressor, reduction of defrosting operations of the exchanger of the lower source, heat accumulation in peak sources and minimisation of the need to use additional heat sources to ensure operation of the compressor within the operating envelope.

摘要： A system and method for reducing the refrigerant charge in a refrigeration system by preheating the liquid refrigerant before it is introduced to the evaporator inlet. When refrigerant liquid is introduced to the evaporator inlet, a portion of the refrigerant liquid vaporizes. The refrigerant vapor displaces refrigerant liquid at the inlet of the evaporator. As more refrigerant vapor is introduced, the amount of liquid inside the evaporator is reduced. A heat exchanger is placed before the liquid refrigerant inlet of the evaporator to generate more vapor when the refrigerant enters the evaporator.

The mass flow ( ṁ F ) of the working fluid is determined using a classification (m) of the opening of the expansion valve (40; 40A, 40B, 40C) and some of the detected thermodynamic parameters ( T entrance , p entrance , p exit ) of the working fluid. A cooling power and/or a heating power ( Q̇ ) of the refrigeration machine (1; 2) and/or heat pump (3; 4) is determined as a function of the mass flow ( ṁ F ) of the working fluid. The energy efficiency of the refrigeration machine and/or heat pump (3; 4) is evaluated by comparing the cooling power and/or heating power (Q) to an electrical power (P el ) used to power the refrigeration machine and/or heat pump.
