The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In some places, such as indoor hot springs, swimming pools, indoor water amusement parks and the like, the energy consumption of operation is large, in order to recover heat in indoor air and reduce operation cost. The embodiment of the utility model provides an air conditioning system, for the more clear technical scheme who expresses this application, follow-up air conditioning system who uses in the natatorium exemplifies. As shown in fig. 1, the air conditioning system includes a heating system 1, a cooling system 2, and at least one heat pump heat recovery unit 3. The heating system 1 may include one or more of a swimming pool water heating device, a heating device, a shower heating device, and the like. The present application does not limit the specific type of equipment in the heating system 1, and the equipment that has a demand for heat may be referred to as the heating system 1. The cooling system 2 may comprise other room air conditioning refrigeration equipment or other cooling systems, etc. The heat pump heat recovery unit 3 is used for recovering the condensation heat generated by the cooling system 2 and transferring the heat to the heating system 1, for example, when the heating system 1 is a swimming pool water heating device, the swimming pool water heating device can convert the heat into the intake water of the swimming pool water. Therefore, the condensation heat of the indoor air is recovered and utilized, the total use energy consumption can be reduced, and the operation cost is saved.
As shown in fig. 1, the heating system 1 has a first liquid outlet a2 and a first liquid inlet a 1. The cooling system 2 has a second liquid outlet port B2 and a second liquid inlet port B1. The at least one heat pump heat recovery unit 3 comprises a first evaporator 31 and a first condenser 32. The first condenser liquid inlet D1 may be connected to the first liquid outlet a2 of the heating system 1 by a pipeline, and the first condenser liquid outlet D2 may be connected to the first liquid inlet a1 of the heating system 1 by a pipeline. The heating system 1 and the first condenser 32, which are communicated in this case, may constitute a first path L1 as shown in fig. 1.
Further, the first evaporator liquid inlet C1 may be communicated with the second liquid outlet B2 of the cooling system 2 by a pipe, and the first evaporator liquid outlet C2 may be communicated with the second liquid inlet B1 of the cooling system 2 by a pipe. In this case, the cooling system 2 and the first evaporator 31 which are communicated with each other may constitute the second path L2 shown in fig. 1 through a duct.
Accordingly, the refrigerant having a low temperature in the first evaporator 31 flows into the first evaporator 31 from the second liquid outlet B2 of the cooling system 2 through the second path L2, and then, the liquid and the refrigerant in the first evaporator 31 can be subjected to heat conversion. That is, the low-temperature refrigerant absorbs the heat of the liquid in the second path L2 during the heat conversion process and is vaporized, thereby achieving the effect of cooling the liquid in the second path L2. Therefore, the first evaporator 31 in the second path L2 can cool the liquid from the second liquid outlet B2 of the cooling system 2 and output the cooled liquid to the second liquid inlet B1 of the cooling system 2, so that the temperature of the second liquid inlet B1 of the cooling system 2 is lower than the temperature of the second liquid outlet B2 of the cooling system 2. For example, for convenience of description, the temperature of the liquid in the second liquid inlet B1 of the cooling system 2 can be referred to as the temperature before use, and the temperature before use of the liquid is generally 5 ℃ to 10 ℃. The temperature of the liquid in the second liquid outlet B2 of the cooling system 2 may be referred to as the temperature after use, and may be 10 ℃ to 15 ℃. Wherein the temperature of the liquid after use is higher than the temperature before use.
In addition, the liquid passing through the first condenser 32 is heat-converted from the vaporized refrigerant, and the vaporized refrigerant is liquefied and releases heat by the first condenser 32, thereby heating the first path L1 to the liquid passing through the first condenser 32. The liquid from the first liquid outlet A2 of the heating system 1 is heated and then input into the first liquid inlet A1.
To sum up, the embodiment of the present invention provides an air conditioning system, in this way, in second route L2, the liquid that comes out through cooling system 2 second liquid outlet B2 is carried to cooling system 2 through second route L2 after the first evaporator 31 absorbs heat and refrigerates. The cooling system 2 can be recycled into the cooling system 2 for cooling exchange after receiving the cooled liquid from the first evaporator liquid outlet C2. As can be seen from the above description, the temperature of the liquid output from the first condenser 32 increases after the first condenser 32 and the first evaporator 31 perform heat conversion by the refrigerant. Based on this, the liquid heated by the first condenser 32 can be used for the heating system 1 to perform heat conversion and recycling, so that the liquid in the first path L1 is heated to recover the heat generated by the cooling system 2, and the energy consumption of the whole natatorium is saved.
The above-mentioned structure of the cooling system 2 is exemplified below, for example, in some embodiments of the present application, in order to solve the problem of indoor dehumidification due to high humidity (e.g., in summer in a natatorium). As shown in fig. 2, the cooling system 2 may include a dehumidifying component 21 in the air conditioning unit 100, where the dehumidifying component 21 has a cooling inlet and a cooling outlet, and the cooling inlet is communicated with the first evaporator outlet C2 (it should be noted that the communication here may be direct communication or indirect communication, for example, the indirect communication may be that liquid enters the second inlet B1 of the cooling system 2 from the first evaporator outlet C2 and then enters the cooling inlet, for example, the cooling inlet is equivalent to the second inlet B1, which will not be described in detail later). The cooling liquid outlet is in communication with the first evaporator liquid inlet C1 (it should be noted that the communication here may be direct communication or indirect communication, for example, the indirect communication may be that liquid comes out from the cooling liquid outlet of the dehumidification assembly through the second liquid outlet B2 of the cooling system 2 and then enters the first evaporator liquid inlet C1. of course, the indirect communication may also be direct communication, for example, the cooling liquid outlet is equivalent to the second liquid outlet B2, and will not be described in detail later).
In this case, the dehumidifying unit 21 is used to condense the humid air in the indoor natatorium (the temperature of the humid air in the natatorium is generally maintained in the range of 27 to 29 ℃) to a dew point temperature or lower, and after moisture is separated out, reduce the water vapor in the air. For example, as shown in fig. 2, since the humid air is condensed to release heat, the liquid for condensation in the dehumidifying module 21 is heated, and the liquid at the cooling liquid outlet of the dehumidifying module 21 is heated and then delivered to the first evaporator 31.
The heated liquid enters the first evaporator 31 through the second path L2, the refrigerant in the first evaporator 31 absorbs heat and cools the liquid in the second path L2, and the cooled liquid returns to the dehumidification module 21 through the second path L2 for use. The vaporized refrigerant is liquefied and released heat in the first condenser 32, so that the liquid in the first path L1 passing through the first condenser 32 is heated and then delivered to the heating system 1 for use, and thus, the dehumidifying component 21 can achieve the purpose of dehumidification to recycle heat.
The temperature parameter of the liquid in the above structure is exemplified below, for example, in some embodiments of the present application, since the temperature of the dehumidifying component 21 for dehumidifying is generally 5 ℃ to 10 ℃, that is, the temperature of the cooling liquid inlet of the dehumidifying component 21. The temperature of the dehumidifying component 21 after dehumidifying the humid air in the natatorium can be raised to 10-15 ℃, namely the temperature of the cooling liquid outlet of the dehumidifying component 21.
For example, in some embodiments of the present application, the dehumidification temperature required by the dehumidification unit 21 is 7 ℃, the temperature of the liquid outlet for cooling by the dehumidification unit 21 can be increased to 12 ℃ after dehumidification by the dehumidification unit 21, the heated liquid enters the first evaporator 31, and after cooling by heat exchange with the refrigerant liquid in the first evaporator 31 to 7 ℃, the heated liquid flows out from the liquid outlet of the first evaporator 31 and flows into the dehumidification unit 21 again through the second path L2, so as to form a cycle operation.
For example, the dehumidification assembly 21 may have cooling inlet temperatures of 5 ℃, 7 ℃ and 10 ℃. The temperature of the cooling liquid outlet of the dehumidifying module 21 may be 10 ℃, 12 ℃ and 15 ℃. The temperature of the first evaporator inlet C1 can be 10 ℃, 12 ℃ and 15 ℃, and the temperature of the first evaporator outlet C2 can be 5 ℃, 7 ℃ and 10 ℃.
Since the temperature in the natatorium room needs to be maintained in the range of 27-29 ℃, the heating system 1 of the present application may further include a wind heating module 11 in the air conditioning unit 100 in fig. 2, wherein the wind heating module 11 has a heating liquid inlet and a heating liquid outlet. The heat supply liquid inlet is communicated with the first condenser liquid outlet D2 (the communication mentioned here can be direct communication or indirect communication, which is not described in detail), and the heat supply liquid outlet is communicated with the first condenser liquid inlet D1 (the communication mentioned here can be direct communication or indirect communication, which is not described in detail), and the air heating assembly 11 is used for heating air entering the room so that the room temperature is in the range of 27-29 ℃.
The temperature parameters are partially exemplified below, for example, in some embodiments of the present application, the desired liquid temperature of the air heating assembly 11 may be 42 ℃ to 50 ℃, i.e., the heated liquid inlet of the air heating assembly 11. Because the air heating assembly 11 heats the passing air, a part of liquid heat in the air heating assembly 11 is taken away by the air, and thus, the temperature of a heat supply liquid outlet of the air heating assembly 11 can be 37-45 ℃.
For example, in some embodiments of the present application, when the temperature of the liquid required by the wind heating element 11 is 45 ℃, the temperature of the hot liquid outlet after passing through the wind heating element 11 may be 40 ℃, and the liquid enters the first condenser inlet port D1 through the first path L1 and then is heated by heat exchange with the refrigerant liquid in the first evaporator 31, so that the temperature of the first condenser outlet port D2 may be 45 ℃, and thus, the temperature of the liquid entering the wind heating element 11 through the first path L1 may be 45 ℃, so as to form a cycle operation.
For example, the temperature of the first condenser inlet port D1 may be 37 ℃, 40 ℃ and 45 ℃, and the temperature via the first condenser outlet port D2 may be 42 ℃, 45 ℃ and 50 ℃. The temperature of the heat supply liquid inlet of the air heating component 11 can be 42 ℃, 45 ℃ and 50 ℃, and the temperature of the heat supply liquid outlet of the air heating component 11 can be 37 ℃, 40 ℃ and 45 ℃.
From the above, the following conclusions can be drawn:
the temperature difference Δ T1 before and after the liquid in the first path L1 passes through the first condenser 32 is 45 ℃ to 40 ℃ to 5 ℃.
The temperature difference Δ T2 between the liquid in the second path L2 before and after passing through the first evaporator 31 is 7 ℃ to 12 ℃ to-5 ℃.
In this way, the liquid in the first path L1 rises by 5 ℃, and the liquid in the second path L2 falls by 5 ℃, that is, the heat conversion between the first path L1 and the second path L2 is realized by the heat pump heat recovery unit 3.
It should be noted that:
the heat pump heat recovery unit 3 may further include an expansion valve, a compressor, a control system, and the like, wherein the compressor is used for compressing the low-pressure low-temperature refrigerant vapor into the high-pressure high-temperature refrigerant vapor to create a condition for condensing at a higher temperature. The control system is used for controlling the operation of each component.
The liquid refrigerant in the first evaporator 31 absorbs the liquid heat in the first path L1, and the liquid refrigerant absorbs heat to form low-temperature low-pressure refrigerant vapor, and the compressor applies work to the low-temperature low-pressure refrigerant vapor, so that the low-temperature low-pressure refrigerant vapor becomes high-temperature high-pressure refrigerant vapor. When the high-temperature and high-pressure refrigerant vapor passes through the first condenser 32, the refrigerant vapor starts to liquefy and release heat, so that the high-temperature and high-pressure refrigerant vapor forms a low-temperature and high-pressure liquid refrigerant, the refrigerant is throttled by the expansion valve to form a low-temperature and low-pressure liquid refrigerant, and the refrigerant returns to the first evaporator 31 again to absorb the heat of the liquid in the first path L1 to form low-temperature and low-pressure refrigerant vapor, thereby forming a cycle.
In order to ensure that the liquid in the pipe between the heating system 1 and the first condenser 32 has sufficient kinetic energy to circulate, at least one hot water circulation pump 6 may be arranged between the first liquid outlet a2 and the first condenser inlet D1 of the heating system 1, as shown in fig. 2. In order to ensure that the liquid in the conduit between the cooling system 2 and the first evaporator 31 has sufficient kinetic energy to circulate, at least one cooling liquid circulation pump 7 may be provided between the second liquid outlet B2 of the cooling system 2 and the first evaporator liquid inlet C1.
When the heat demand in the natatorium room is large (for example, in winter), not only the hot water of the natatorium shower device and the swimming pool needs heat, but also the heating device needs heat supply, therefore, in order to ensure normal operation, as shown in fig. 3, the air conditioning system may further include an additional heating system 4, a pipeline between the additional heating system 4 and the heating system 1 forms a third path L3, and the additional heating system 4 has an additional heating system inlet E1 and an additional heating system outlet E2. The fluid inlet E1 of the heat supplementing system is communicated with the first fluid outlet a2 of the heat supply system 1, and the fluid outlet E2 of the heat supplementing system is communicated with the first fluid inlet a1 of the heat supply system. The heat supply system 1 is provided with a first inlet port A1 for supplying heat to the heat supply system 4. When the first condenser 32 provides insufficient heat to the heating system 1, the thermal compensation system 4 may be activated to meet the heat requirement, and the thermal compensation system 4 may be turned on according to the requirement in the natatorium and adjust the liquid flow in the third path L3 accordingly.
For example, in summer, the requirement for cooling capacity in the natatorium is large, and refrigeration equipment in the natatorium needs to be refrigerated, so as shown in fig. 4, the cooling system 2 may further include a supplementary cooling system 5, a fourth path L4 is formed by a pipeline between the supplementary cooling system 5 and the cooling system 2, and the supplementary cooling system 5 has a supplementary cooling system liquid inlet F1 and a supplementary cooling system liquid outlet F2. The liquid inlet F1 of the cooling supplement system is communicated with the second liquid outlet B2 of the cooling supply system 2, the liquid outlet F2 of the cooling supplement system is communicated with the second liquid inlet B1 of the cooling supply system, and the cooling supplement system 5 is used for providing a cooling source for the cooling supply system 2. When the first evaporator 31 provides insufficient cooling capacity, the supplementary cooling system 5 can be activated to meet the cooling capacity demand. The flow rate of the liquid in the fourth path L4 of the cooling system 5 can be switched on and adjusted accordingly according to the requirements in the natatorium.
The above-mentioned structure of the supplementary cooling system 5 is exemplified below, for example, in some embodiments of the present application, as shown in fig. 5, the supplementary cooling system 5 may include at least one refrigerator group 51 and a cooling tower 52. The refrigeration unit 51 may include a second evaporator 511 and a second condenser 512. The piping between the second evaporation 511 and the cooling system 2 constitutes a fourth path L4. The second evaporator 511 has a second evaporator liquid inlet G1 and a second evaporator liquid outlet G2. In this case, the second evaporator inlet G1 is in communication with the second outlet B2 of the cooling system 2, and the second evaporator outlet G2 is in communication with the second inlet B1 of the cooling system 2. Thus, the second evaporator 511 can cool the liquid in the fourth path L4.
Furthermore, the pipeline between the cooling tower 52 and the second condenser 512 forms a fifth path L5, the cooling tower 52 has a cooling tower 52 liquid outlet and a cooling tower 52 liquid inlet, the cooling tower 52 liquid outlet is communicated with the liquid inlet of the second condenser 512, and the cooling tower 52 liquid inlet is communicated with the liquid outlet of the second condenser 512. In this way, the cooling tower 52 can take away the heat of the liquefied refrigerant fluid in the second condenser 512, so that the refrigerant fluid can enter the second evaporator 511 again for use. The supplementary cooling system 5 further includes a cooling circulation pump 53. The cooling circulation pump 12 is located between the second condenser 512 and the liquid outlet of the cooling tower 52 to provide the kinetic energy of the circulation in the pipe of the fifth path L5.
For example, in some embodiments of the present application, in the fourth path L4, the temperature of the cooling liquid required by the cooling system 2 is 5 ℃ to 10 ℃, the temperature of the cooling liquid after the cooling system 2 is 10 ℃ to 15 ℃, and the temperature of the second evaporator liquid inlet G1 communicated with the second liquid outlet B2 of the cooling system is 10 ℃ to 15 ℃. The temperature of the inlet water to the cooling tower 52 is generally 35-42 ℃, and the temperature of the inlet water cooled by the cooling tower 52 and sent to the second condenser 512 in the fifth path may be 30-37 ℃.
In order to more clearly express the relationship between the above mentioned temperature parameters, the above temperature parameters are partially exemplified below, for example, in some embodiments of the present application, the liquid temperature before use of the cooling system 2 is 7 ℃, the liquid temperature after use is increased to 12 ℃, the liquid enters the second evaporator liquid inlet port G1 in the fourth path through the second liquid outlet port B2 of the cooling system 2, after the heat absorption and the refrigeration of the second evaporator 511, the temperature of the second evaporator liquid outlet port G2 can be decreased to 7 ℃, and then the liquid is delivered to the second liquid inlet port B1 of the cooling system by the fourth path L4, so as to be recycled.
In this case, the liquid in the fourth path L4 is cooled and transfers heat to the refrigerant liquid in the second evaporator 511, and the refrigerant liquid is heated and gasified, thereby being liquefied and released heat in the second condenser 512 to heat the liquid flowing in the second condenser. The outlet temperature of the cooling tower 52 may be 32 ℃, the temperature of the liquid in the fifth path L5 may be raised to 37 ℃ after the heat is converted by the second condenser 512, and finally the liquid at 37 ℃ is transported to the inlet of the cooling tower 52 by the fifth path L5 to be cooled to 32 ℃, so as to be recycled.
For example, the inlet temperature of the second condenser 512 may be 30 ℃, 32 ℃ and 37 ℃, and the outlet temperature of the second condenser 512 may be 35 ℃, 37 ℃ and 42 ℃. The outlet temperature of the cooling tower 52 can be 30 ℃, 32 ℃ and 37 ℃, and the inlet temperature of the cooling tower 52 can be 35 ℃, 37 ℃ and 42 ℃.
