- the heat pump comprises, generically, an evaporator in which a refrigerant absorbs heat, the refrigerant there changes state and passes from the liquid phase to the gas phase.
- the fluid is then compressed in a compressor where its pressure and temperature increase sharply.

- FIGS. 1 to 3 represents a heat pump-pump 1 comprising a heat pump 2 equipped with:
- the compressor 5 is mechanically coupled to a fuel powered thermal motor.
- a refrigerant circulates in the heat pump 2.
- the refrigerant is a zeotropic mixture (also known as a temperature slip mixture).
- the zeotropic mixture comprises several fluids whose volatilities are different from each other, and consequently, the evaporation temperatures are also different from each other.
- the thermal engine 7 is cooled using a cooling system 8 comprising:
- 11 engine recuperator a heat exchanger, hereinafter called 11 engine recuperator.
- a cooling liquid for example brine, circulates in the cooling circuit 9 by the action of the cooling pump 10.
- the coolant rises in temperature in the engine 7 thermal, and it drops in temperature in the recuperator 11 engine.
- the combustion of the fuel in the combustion engine generates exhaust gases.
- the exhaust gases exit through an exhaust duct 12 before entering a heat exchanger 13 of the exhaust gas.
- the heat of the exhaust gas is removed by means of a recovery loop 14.
- the recovery loop 14 is provided with an exhaust fluid circuit 15 in which circulates a coolant.
- An exhaust pump 16 ensures the circulation of the coolant in the exhaust fluid circuit.
- the fluidic exhaust circuit passes through an exhaust heat recuperator 17 in order to restore the heat acquired in the heat exchanger 13 of the exhaust gas.
- the heat pump-motor 1 comprises a heat-exchange loop 18 provided with a heat-transfer circuit 19 in which a coolant circulates.
- a caloporous pump 20 ensures the circulation of the coolant in the heat transfer circuit 19.
- the loop 18 heat sink is arranged so that the heat transfer circuit 19 passes through the condenser 4 of the heat pump 2, the recuperator 11 engine, the recuperator 17 exhaust and a restatrix 21 heat.
- the heat-sink loop 18 thus recycles, in increasing order of temperatures, the heat of the heat engine 7, the exhaust gas and the condenser 4, thanks to the heat-exchange loop 18. It restores this heat through the heat restatrix 21.
- the heat pump 1 pumps industrial wastewater or gray water from homes to recycle their heat.
- the gray water enters the heat pump 1 at the evaporator 3 of the heat pump by an inlet 22 evaporator at a temperature t- ⁇ .
- the greywater leave the heat pump 1 by an evaporator outlet 23 at a temperature t 2 lower than t- ⁇ .
- a circuit 24 for recycling heat through the heat restatrix 21 In this recycling circuit 24, circulates a heat transfer fluid entering the heat restatrix 21 by a restitutant inlet at a temperature t 3 .
- the heat transfer fluid exits the heat restatrix 21 by an output 26 restatrix, at a temperature t 4 greater than t 3 .
- thermal power recovered at the engine 7 thermal and exhaust.
- the numerator and the denominator are divided by the compression power W:
- equation A Adding the thermal efficiency R t h, in theory, we obtain the following equation, hereinafter referred to as equation A:
- Equation A above indicates that the primary energy coefficient of the heat pump-pump 1 is a function of the coefficient of performance of the heat pump 2, the mechanical efficiency of the heat engine 7 and the energy recovery efficiency. thermal.
- equation B
- equation B establishes the ratio between the two heat sources based only on the primary energy coefficient, the mechanical efficiency of the engine and the heat recovery efficiency lost by the engine.
- the mathematical equation B makes it possible to make an important observation on Q 0 .
- the primary energy coefficient is already about 1.9 since the power Q 0 is equal to the combustion power Q CO mb-
- the primary energy coefficient of the heat pump 1 is even higher than the cooling capacity is greater than the combustion power.
- the power of the engine is variable. The combustion power can then be adequately adjusted to be sufficiently lower than the power refrigerant in order to improve the energy performance of the motor pump 1 heat.
- the embodiments shown in the figures illustrate an arrangement of the heat pump-1 to recover about 80% of the available energy on the engine 7 thermal.
- the energy available on the thermal engine 7 corresponds to the energy recovered by cooling the thermal engine 7 and the energy recovered on the exhaust gases.
- the mechanical efficiency of the heat engine 7 is at least 0.3 and the coefficient of performance of the heat pump 2 is between 2 and 10.
- the refrigerant in the heat pump 2 varies between 28 ° C and 58 ° C to cool the wastewater from 60 ° C to 30 ° C.
- the average evaporation temperature of the refrigerant in the evaporator 3 is about 43 ° C.
- the recovered power Q rec in the loop 18 heat sink corresponds to the sum of the power available to the condenser 4 Q K , the cooling power in the recuperator 11 engine and hereinafter called Q re f and the available power in the recuperator 17 exhaust Q eC h which is expressed according to the thermal efficiency R th -
- the thermal distribution in the caloporous loop 18 is therefore as follows:
- the loop 18 caloportrice allows a warming of 50 ° C. According to the percentages described in the previous paragraph, it can be deduced that the condenser 4 allows a temperature rise of 40 ° C, from 70 ° C to 110 ° C, the 11 engine recuperator contributes up to 8% or 4 ° C, from 110 ° C to 114 ° C and finally the recuperator 17 exhaust brings 12% or 6 ° C from 114 ° C to 120 ° C.
- the average condensing temperature of the refrigerant of the heat pump 2 is about 92 ° C. which corresponds to a temperature difference with the evaporator 3 of 39 ° C. From there, the coefficient of performance of the heat pump 2 is determined as follows with the Carnot method:
- the typical distribution of thermal power as a function of the combustion power Q CO mb is as follows: about 35% comes from mechanical work, 20% from cooling power Q ref (steady state measured value for a heat engine), 35% of the exhaust and finally 10% of the radiation losses and heat transferred to the engine oil.
- the condenser 4 contributes 76% here and the recovery unit 11 engine and 17 exhaust recuperator contributes up to 24% in the total power recovered.
- the evaporator 3 thus contributes exactly 59% of the total thermal power recovered, which corresponds to Q 0 .
- the remaining power is 41%, comes from the thermal power Q CO mb (recovered on the exhaust gas and on the cooling circuit of the engine). This makes it possible to obtain, at the level of the recycling circuit 24, a temperature t 4 of 120 ° C. with an average use of 95 ° C. and this from greywater available in the evaporator at an average temperature of 43 ° C. .
- the energy valorization primary is done with a factor of 2 and the power extracted at the cold source is greater than the power provided by the fuel.
- the various ratios established allow a fine regulation of the heat pump-motor and make it possible to reach the highest energy efficiencies.
- the heat pump 1 advantageously comprises a computer control unit (not shown in the figures).
- the computer control unit is equipped with a computer program defining a control strategy for the heat pump motor pump 1.
- the strategy may be based on several different factors, one of them may be to make the recovered power at the caloporous loop 18 proportional to the power of combustion.
- the computer program can vary the rotational speed of the thermal engine 7 so that the combustion power is adjustable between 30% and 100% of the total available combustion power. It follows then a rule of growth or decay of the speed of the thermal engine 7 which will cause that of the compressor 5 and therefore that of the cooling capacity.
- the heat pump 2 is provided with a temperature probe and a pressure sensor (not shown in the figures) upstream and downstream of the evaporator 3 in the pump 2. heat.
- the measured temperatures and pressures make it possible, from given charts for a given refrigerant, to determine the enthalpy of the refrigerant upstream and downstream of the evaporator 3.
- the heat pump 2 is also provided with a volume flow sensor for measuring the flow rate of the refrigerant in the heat pump 2. From the volume flow, the control unit calculates the mass flow rate by multiplying by the density of the refrigerant which is obviously known at a given temperature. The control unit then precisely determines the cooling capacity available in the evaporator 3 by making the product of the refrigerant mass flow rate by the enthalpy difference between the upstream and the downstream of the evaporator 3.
- the combustion power is determined by making the product of the amount of fuel injected into the heat engine by the higher or lower calorific value of the fuel.
- Embodiment 1 In Figure 1 is shown a heat pump motor 1 as described above in the part common to different embodiments.
- the heat-exchange loop 18 successively traverses the condenser 4, the engine recuperator 11, the exhaust recuperator 17 and the retractor 21.
- the exhaust recuperator 17 is the one where the temperature is the highest. This is the reason why the exhaust recuperator 17 is positioned at the end of the course, just before the restorer 21. In fact, the recycling of the heat is better when the heat transfer fluid circulates successively through exchangers whose temperature is growing. The opposite would be pure loss. Through this reasoning, it is advantageous for the engine recuperator 11 and the exhaust recuperator 17 to work against each other. current. In this way, the coldest heat transfer fluid is in contact with the part of the coolers 11, 17 the coldest and conversely at the end of the heat transfer fluid in the recuperators 11, 17. 2 nd Embodiment
- FIG. 2 illustrates a variant of the loop 18 caloporter.
- the recuperator 11 engine is positioned before the condenser 4.
- the heat transfer fluid from the restorer 21 is first warmed before joining the condenser 4 and the recuperator 17 exhaust.
- the loop 18 heat sink is identical to the first embodiment.
- the difference lies in the fact that a residual heat exchanger 27 is added so as to capture the residual heat of the exhaust gas at the outlet of the exhaust exchanger 13.
- the residual heat exchanger 27 delivers the heat to a residual recuperator 28 situated between the evaporator 3 and the compressor 5 of the heat pump 2.
- the refrigerant is reheated by means of the residual recuperator 28 before being compressed in the compressor 5. This arrangement is however only of interest if the temperature of the exhaust gases in the residual heat exchanger 27 is greater than the temperature of the refrigerant leaving the evaporator 3.
