From the external consumer or heat exchanger, the liquid coolant, which has absorbed heat there, flows via the fourth connection 1 13 back into the heating / cooling module 1 and in particular into the valve block 121.
- the liquid coolant flows through the node e and H marked connection of the first switching valve 123 and its unmarked connection to the liquid cooling jacket of the compressor 29. It occurs there on the fifth Coolant interface 17 on and out of the sixth coolant interface 19 again.
- the liquid coolant which has already absorbed heat in the external consumer or heat exchanger, absorbs further heat, in particular waste heat, in the liquid cooling jacket 55 of the compressor 29 and optionally also in at least one further liquid cooling jacket connected in series then via the unmarked connection of the second changeover valve 125 to its designated H port.
- the first valve actuator 135 passes through the node h and the third coolant interface 11 into the evaporator heat exchanger unit 5 and in particular into the evaporator 95 and the second liquid heat exchanger 93, respectively it flows in the direction of arrow 117.
- the heat which was previously absorbed externally as well as in the at least one liquid cooling jacket, is at least partially dissipated to the refrigerant, which also flows through the evaporator 95. It then leaves the evaporator heat exchanger unit 5 through the fourth coolant interface 13 in order to again flow through the third port 1 1 1 to the external load or heat exchanger.
- the liquid coolant thus takes in the external consumer or heat exchanger and in the liquid cooling jacket 55 of the compressor 29 and optionally in at least one further liquid cooling jacket heat, which it emits in the evaporator 95 to the refrigerant of the refrigerant circuit before it flows back to the external load or heat exchanger.
- the cooling operation of the heating / cooling module 1 is explained in more detail below:
- a heat reservoir should be cooled.
- an external consumer or heat exchanger is supplied with cold liquid coolant. It absorbs heat there and thus cools the heat reservoir in communication with the consumer or heat exchanger.
- the liquid coolant then flows via the fourth connection 113 back into the heating / cooling module 1 and in particular into the valve block 121.
- the liquid coolant flows over the Node e and the first valve actuator 135, which is opened in the cooling mode, to the node h and the third coolant interface 1 1.
- the H marked connection of the second switching valve 125 is locked.
- the liquid coolant flows through the evaporator 95 or the second liquid heat exchanger 93 in the direction of the arrow 1 17 and flows through the fourth coolant interface 13 and the third port 1 11 back to the external load or heat exchanger.
- the liquid coolant releases heat to the refrigerant, which also flows through the evaporator 95, and is itself cooled in this way.
- the warm liquid-coolant circuit serves either to heat a heat reservoir or to generate heat, in particular special dissipate heat to the environment.
- the focus of the function of the heating / cooling module 1 in cooling mode is on the cooling of the cold heat reservoir and not on the heating of another heat reservoir. Accordingly, on the warm side, only heat is dissipated, without the temperature of a heat reservoir increasing, or at least not reaching a certain desired temperature is in the foreground, so that losses in performance can be tolerated during heating.
- the warm liquid coolant flows via the first port 107 to an external consumer or heat exchanger where it gives off heat and via the second port 109 back into the heating / cooling module 1. Here it enters via the first coolant interface 7 in the gas cooler 25 and the first liquid heat exchanger 23 and flows through it in the direction of the arrow 115. It absorbs heat from the gas cooler 25 also flowing through the refrigerant.
- the liquid coolant continues to flow via the node f via the fifth coolant interface 17 to the liquid cooling jacket 55 of the compressor 29 and optionally also to the further liquid cooling jacket 45 of the control device 15.
- the liquid cooling jacket of the compressor unit is included in the cooling operation and particularly preferably with the remaining liquid Cooling jackets 45, 55 connected in series. The refrigerant compressed in the compressor unit can then be deprived of heat by means of the liquid cooling jacket, so that the cooling capacity of the heating / cooling module 1 is ultimately increased in the manner already described.
- the liquid coolant absorbs the waste heat of at least one of the components and flows via the sixth coolant interface 19 to the unmarked connection of the second changeover valve 125, which is connected in the cooling operation to the connection marked K, while the port marked H is disabled. From there, the liquid coolant in turn flows via the node g and the first port 107 to the external consumer or heat exchanger. In this case, the second valve actuator 137 is locked.
- the liquid coolant on the warm side of the heating / cooling module 1 in the cooling operation absorbs heat in the gas cooler 25 and waste heat from the liquid cooling jacket 55 of the compressor 29 and possibly also the other liquid cooling jackets dissipates, although therefore in cooling mode more heat sources, namely in addition to the gas cooler 25 nor the at least one liquid cooling jacket 55 of the compressor 29 and optionally the other liquid cooling jackets are included in the warm coolant circuit, however, a lower heating power is available than in the heating operation. This is because in the cold coolant circuit except the external consumer or heat exchanger of the heat reservoir to be cooled no further heat sources are included.
- This effect overcompensates for the additional heat sources included in the warm coolant circuit in cooling mode. This is especially true when the refrigerant in the compressor unit heat was removed through the liquid cooling jacket of the same.
- the heat extracted from the compressed refrigerant is available to the liquid-refrigerant circuit of the hot side via the liquid cooling jacket of the compressor unit, so that the heat loss due to the colder refrigerant in the gas cooler in a certain way Balances the warm side.
- the heating / cooling module 1 can be used in heating mode or in cooling mode.
- the heating or cooling capacity of the heating / cooling module 1, in particular via a speed of the compressor 29 is controlled and / or regulated.
- a temperature sensor can be provided in or on the heat reservoir to be heated or cooled, which transmits an actual temperature to the control device 15, preferably via an interface.
- connections 107, 109, 11 1 1, 13 preferably have quick-release couplings with the aid of which external fluid Coolant flow paths, such as pipes or hoses can be connected to the terminals.
- the heating / cooling module 1 is offered as a compact device with a frame designed as a support frame, for example, in a hardware store for purchase or loan, the borrower or purchaser of the heating / cooling module 1 this via the terminals 107, 109, 1 11, 1 13 to its individual external infrastructure. It is also possible for a purchaser of the heating / cooling module 1 to install this preferably in the trunk of his motor vehicle and to connect it to the water connections thereof.
- the heating / cooling module 1 then serves as a sort of retrofit unit for a vehicle air conditioning.
- FIG. 5 shows a second exemplary embodiment of the heating / cooling module 1 or, in particular, a second exemplary embodiment of the valve block 121.
- Identical and functionally identical elements are provided with the same reference numerals, so that reference is made to the preceding description.
- the functionality and assignment of the liquid-coolant streams in the heating or cooling mode of the embodiment shown in Figure 5 corresponds completely to that of the embodiment of FIG 4. It is so far referred to the preceding presentation.
- the valve device 131 is designed differently here: It comprises two temperature-controlled valves 139, 141. These preferably comprise a bimetallic control or bimetallic adjusting device.
- a dashed line L indicates that the first, temperature-controlled valve 139 detects the temperature of the liquid coolant, which enters the heating / cooling module 1 through the fourth connection 13. It is closed at low temperature and, in a preferred embodiment, opens when the coolant at the measuring location, that is to say in the region of the fourth connection 113, has a temperature of> 15 ° C.
- the first temperature-controlled valve 139 preferably has a switching hysteresis of particularly preferably approximately 3 to 5 Kelvin. Thus, after being opened by raising the temperature to above 15 ° C, it preferably closes when the temperature at the measuring site decreases to about 10 to 12 ° C or below.
- the second, temperature-controlled valve 141 By a dashed line L ' is indicated that the second, temperature-controlled valve 141, the temperature of the liquid coolant in the region of the sixth coolant interface 19, ie at the coolant outlet of the liquid cooling jacket 55 of the compressor 29 and the series-connected liquid cooling jackets detected. It is open when the coolant is comparatively cold, and in a preferred embodiment closes at a temperature of the coolant at the measuring location of> 50 ° C.
- the second, temperature-controlled valve 141 has a switching hysteresis of particularly preferably about 3 to 5 Kelvin.
- the second, temperature-controlled valve 141 after being closed by raising the temperature to above 50 ° C, it preferably opens again when the temperature at the measurement site decreases to about 45 to 47 ° C or below.
- the first, temperature controlled valve 139 is in fluid communication with its inlet to the first node e. Its outlet is in fluid communication with the fourth node h.
- the inlet of the second, Temperature controlled valve 141 is in fluid communication with the second node f.
- the outlet of the second temperature controlled valve 141 is in fluid communication with the third node g.
- temperature-controlled valve 139 With regard to the first, temperature-controlled valve 139, the following appears:
- the coolant flowing from the evaporator 95 via the third connection 11 to an external consumer or heat exchanger returns to the fourth connection 13, where it then has a temperature at which the first temperature-controlled valve 139 is closed , Therefore, it flows - as already explained in connection with Figure 4 - via the node e to the H marked connection of the first switching valve 123. It thus does not flow through in heating operation, the first, temperature-controlled valve 139.
- the liquid coolant increases due to predominantly cooling a heat reservoir or due to the increased cooling capacity in the external load or heat exchanger comparatively much heat and therefore reaches a temperature to the fourth port 1 13, in which the first, temperature-controlled valve 139 is opened.
- the liquid coolant flowing in the heating operation to the measuring location of the second, temperature-controlled valve 141 has not passed through the gas cooler 25 but only the liquid cooling jacket 55 of the compressor 29 and optionally at least one further liquid cooling jacket. It is therefore relatively cold, or has a temperature at which the second, temperature-controlled valve 141 is opened. Therefore, the liquid refrigerant flowing from the gas cooler 25 via the second coolant interface 9 can flow to the first port 107 via the node f through the opened second temperature-controlled valve 141 and the node g.
- the liquid coolant which reaches the measuring location of the second, temperature-controlled valve 141, has previously not only passed at least one liquid cooling jacket, but additionally the gas cooler 25. It is therefore comparatively warm and in particular has a temperature at which the second, temperature-controlled valve 141 is closed. Therefore, the liquid refrigerant flowing from the gas cooler 25 via the second coolant interface 9 can not flow via the second temperature-controlled valve 141, but flows instead through the node f and the K-labeled port of the first one connected to the unmarked port Changeover valve 123.
- the equipped with two temperature-controlled valves 139, 141 valve device 131 thus implements the same functionality like the corresponding valve device 131 according to FIG. 4, which comprises the engine valve 133.
- the valves 139, 141 themselves regulate their opening or closing state due to the temperature of the liquid coolant prevailing at the measuring locations. Therefore, this embodiment of the heating / cooling module 1 and the valve block 121 is simpler, but not so variable in terms of switching temperatures.
- different switching temperatures can be adjusted via different temperature-controlled valves with different switching characteristics, in particular with different bimetallic actuators having different switching temperatures.
- the valve block 121 also includes an additional valve, not shown, via which heat from the liquid coolant circuit passing through the gas cooler 25 can be introduced into the liquid coolant circuit during heating operation, which passes through the evaporator 95.
- This valve is preferably designed as a check valve and in particular so that targeted leakage can be realized. It can then be supplied to the evaporator 95 from the gas cooler 25 additional heat, which is useful in particular in a first heating phase of the Schubetnebs for rapid heating.
- the additional valve can also be designed as an electrical or thermostatic valve, in particular if such a control is desired.
- the separate hot and cold liquid-coolant circuits are connected in order to transfer part of the heat from the warm liquid-coolant circuit into the cold liquid-coolant circuit and, in particular, to the to feed steamer 95.
- the heat output increases overall, because the additional heat is coupled into the refrigerant circuit, there to supply mechanical energy by means of the compressor 29 as an increased heating power - according to the principle of the heat pump - turn to the gas cooler 25 and thus the warm liquid coolant circuit to be supplied.
- valve block 121 preferably also includes a mixing valve, also not shown, through which hot liquid coolant from the warm liquid-refrigerant circuit can be mixed with cold liquid coolant from the cold liquid-coolant circuit.
- the liquid coolant which can be removed from the mixing valve is then available for the temperature control of a consumer with liquid coolant of a desired temperature.
- the temperature of the flowing from the mixing valve to a consumer liquid coolant is preferably controlled and / or regulated.
- the corresponding control and / or regulation is preferably also taken over by the control device 15.
- the mixing valve is connected with its connection for hot liquid coolant with a warmest point of the heating / cooling module 1, which is marked in Figure 5 with the letter W. This is arranged directly at the outlet of the liquid coolant from the gas cooler 25.
- the mixing valve is preferably connected to a coldest point of the heating / cooling module 1, which in Figure 5 is marked with the letter C. This is arranged directly at the outlet of the evaporator 95.
- lines for the liquid coolant are preferably structurally combined together with the valve block 121 to form a coolant block.
- the compressor heat exchanger unit 3 and the evaporator heat exchanger unit 5 are structurally combined to form a refrigerant block.
- Figure 6 shows a partial view of another embodiment of the heating / cooling module 1.
- the frame 143 is shown, which the compressor heat exchanger unit 3, the evaporator heat exchanger unit 5, the controller 15, the terminals 107, 109, 11 1, 1 13, and preferably also not shown illustrated valve block 121 includes.
- the frame 143 is designed as a carrying frame and here comprises at a top of the heating / cooling module 1, a first support portion 145 with a carrying handle 147.
- the heating / cooling module 1 can thus be very easily grasped and worn like a suitcase.
- Laterally on the frame 143 are preferably further support portions 149, 149 'are formed, which here in each case two grip portions 151, 153, 151', 153 'include.
- the frame 143 and thus the heating / cooling module 1 also very easy laterally and especially easily gripped by two people, carried and lifted.
- the frame 143 preferably surrounds the heating / cooling module 1 from all sides, so that it effectively secures it against impacts, in particular during transport. Furthermore, the heating / cooling module 1 is very compact, because no elements of the same protrude beyond the frame 143 addition. Overall, it can be seen that with the heating / cooling module 1 a compact, flexible and versatile module for heating, cooling and combined heating / cooling applications, especially in the stationary and especially in the home, yard and garden area given is.
