FIELD: power industry. ^ SUBSTANCE: hot water supply (HWS) method involves water supply to heat pump system (HP), its heating to the specified temperature by means of HP and supply of heated water to consumers. Each HP is used as stage of subsequent heating with heat pump cycle close to triangular Lorentz cycle by choosing the temperature of water supplied to be heated in HP of the first stage, and by adjusting each HP to condensation temperature of its working medium considering the heat released with this stage. All operations of HWS method are used in heating method. Heated water is supplied to consumption system in which it is supplied depending on ambient air temperature with the help of regulator(s) by connecting in the room the heating appliance and/or air heat exchanger, where it is cooled with ambient air to the temperature chosen for this cycle and supplied to be heated in HP of the first stage, and heated air is supplied to the room. ^ EFFECT: inventions allow improving technical and economic efficiency due to operation in the chosen cycle using almost all the HP heat, due to efficient use of heat of the heated room and owing to possibility of operating for heating without HP overload. ^ 6 cl, 6 dwg |
