Subject of the invention based on the simplest application is presented at Fig. 1. When explaining principles of operation, one assumes, that working agent is the propane-butane gas, which in temperature of 5°C, has gas pressure at the level of 4 bar. The working agent in liquid phase in the evaporator (1) collects heat from the low source, evaporates, which results in increasing pressure in the evaporator (1) till level of bar. The working agent in gas phase of 5°C temperature and 4 bar pressure goes through the control valve (2) to the input (3) of Vortex Tube device (4), where is divided into two streams of low pressure: warm (5) of 62°C temperature and cold (6) of -35°C temperature (ratio of warm stream volume to cold stream volume is equal to 4/6). The cold stream (6) through control valve (7) and by means of heat exchanger (8) is warmed up to the temperature of 5°C (using energy of low source), and then mixed (9) with the warm stream (5), which in consequence, gives us stream of working agent going into compressor (10) and having temperature of 22°C. The subsequent stages of the heat pump work are identical as the classical heat pump, what means. That the working agent goes to condenser (11), where is condensed and gives out heat, and then, already in liquid form, through the expansion valve (12) goes to evaporator (1).
