Detailed Description
For the purpose of clearly illustrating the aspects of the present invention, preferred embodiments are given below in conjunction with the accompanying drawings. The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.
The dehumidification or humidification mode of the invention adopts the solution dehumidification and solution regeneration technology, and the essence of the technology is that the acting force of water molecules in the solution is different due to the temperature and the concentration of the solution, so that the difference exists between the acting force of the water molecules in the solution and the acting force of the water molecules in the air; when dehumidification is carried out, the solution in the indoor dehumidifier is low in temperature and high in concentration, and the acting force of water molecules in the solution is larger than that of water molecules in the air, so that the water molecules in the indoor air can be absorbed by the solution; similarly, when the air conditioner heats, the solution in the indoor humidifier has higher temperature and lower concentration, so that the force of water molecules in the solution is smaller than the acting force of water molecules in the air, and the water molecules in the solution are diffused into the indoor air to play a role in humidifying; no matter humidification and dehumidification are completed by utilizing the membrane tissue only allowing water vapor to pass through, so that under two working conditions of dehumidification in summer and humidification in winter, the functions of the dehumidifier and the humidifier played by the humidifying unit can be exchanged at the same time, and the dual-purpose effect of one machine is realized.
However, in consideration of the fact that the concentration and temperature change of the solution affect the absorption or diffusion speed of the water vapor, in order to achieve the purpose of recycling, the solution with lower concentration needs to be heated in the dehumidification cycle to realize the solution regeneration, and in the prior art, an additional heater needs to be configured to increase the temperature of the regenerated solution, which increases the energy consumption and increases the use cost.
Therefore, the invention provides an air conditioning system combining a refrigerant loop and a humidity control loop, as shown in fig. 1, the air conditioning system with the enhanced dehumidification function of the invention comprises an existing refrigerant loop formed by connecting a compressor 1, a first heat exchanger 2 and a second heat exchanger 3, and also comprises a humidity control loop formed by connecting a first humidity control unit 4 and a second humidity control unit 5 through a liquid outlet pipeline 8 and a liquid inlet pipeline 9, a humidity control solution in the first humidity control unit 4 sequentially flows through the liquid outlet pipeline 8, the second humidity control unit 5 and the liquid inlet pipeline 9 and then returns to the first humidity control unit 4 to complete a circulation process, wherein the first humidity control unit 4 and the second humidity control unit 5 can exchange water vapor with external air, dehumidification or humidification operation is completed as required, in order to improve the utilization rate of heat, a third heat exchanger 7 is further arranged in the humidity control loop, and solutions with different temperatures in the liquid outlet pipeline 8 and the liquid inlet pipeline 9 perform heat exchange in the third heat exchanger 7 (ii) a The humidity conditioning circuit comprises a dehumidification circuit and a humidification circuit, wherein the dehumidification circulation path is indicated by solid line arrows and solid line arrows in the figure, and the humidification circulation path is indicated by dashed line arrows and dotted line arrows in the figure, wherein a pipeline between the third heat exchanger 7 and the second humidity conditioning unit 5 passes through the compressor 1 in the dehumidification circuit; in the humidification circuit, the line between the third heat exchanger 7 and the first humidity conditioning unit 4 passes through the compressor 1. Under different working conditions of dehumidification in summer and humidification in winter, the sequence of heating solution flowing through the compressor 1 is different, so that the communication positions of the compressor in the humidification loop and the dehumidification loop are different, and the compressor 1 can generate a large amount of heat in the heating or refrigerating circulation process of an air-conditioning refrigerant, in the traditional air-conditioning system, most of the heat is dissipated to the outdoor environment and is not effectively utilized, so that the compressor 1 is connected into the humidity conditioning loop, the temperature of the solution to be heated is increased by utilizing the heat generated by the compressor 1, the regeneration of the solution is realized, the system does not need to be provided with an additional heater, the whole structure is simplified, and the utilization rate of the air conditioner is increased.
In addition, in the dehumidification or humidification process, in order to preheat the solution or cool the regenerated solution, the humidity control loop is connected with evaporators or condensers of an indoor unit and an outdoor unit in the refrigerant loop, and the specific connection structure is as follows: in the summer dehumidification loop, a pipeline between the third heat exchanger 7 and the second humidity control unit 5 also carries out heat exchange through the second heat exchanger 3, and a pipeline between the third heat exchanger 7 and the first humidity control unit 4 carries out heat exchange through the first heat exchanger 2; in the winter humidifying loop, the pipeline between the third heat exchanger 7 and the second humidifying unit 5 also carries out heat exchange through the second heat exchanger 3, and the pipeline between the third heat exchanger 7 and the first humidifying unit 4 also carries out heat exchange through the first heat exchanger 2.
The circulation and working process of the solution under different working conditions in summer and winter according to the present invention will be described with reference to the accompanying drawings:
(1) in the summer cycle shown in fig. 2, the refrigerant cycle process: compressor 1-second heat exchanger 3-throttle valve 10-first heat exchanger 2-compressor 1; the solution circulation process: the system comprises a first humidity control unit 4, a third heat exchanger 7, a second heat exchanger 3, a compressor 1, a second humidity control unit 5, a pump machine 6, a third heat exchanger 7, a first heat exchanger 2 and a first humidity control unit 4. In the solution circulation, the low-temperature high-concentration humidity control solution absorbs water vapor from indoor return air in the first humidity control unit 4, the solution becomes dilute, and the solution temperature rises in the moisture absorption process, the moisture absorption capacity gradually decreases, so that the dilute solution needs a regeneration process. After the solution coming out of the first humidity control unit 4 along the liquid outlet pipe 8 exchanges heat with the high-temperature regeneration solution coming out of the second humidity control unit 5 along the liquid inlet pipe 9 through the third heat exchanger, the solution continues to enter the second heat exchanger 3 playing a role of a condenser in summer working conditions along the liquid outlet pipe; the solution absorbs the condensation heat released when the high-temperature and high-pressure gas delivered by the compressor 1 is condensed in the second heat exchanger 3; since the temperature required for the regeneration of the solution is relatively high, the solution flows through the compressor 1 after exiting the second heat exchanger 3, and the compressor 1 further heats the solution until the required regeneration temperature is reached. The high-temperature solution passes through the compressor 1 and then enters the second humidity control unit 5 for regeneration. Meanwhile, the outdoor air takes away the water vapor released in the regeneration process, the concentration of the solution is increased, and the regeneration process is completed. Then the high-concentration solution is sent to the first heat exchanger 2 by the pump 6 for cooling, and the cooling capacity is provided by the first heat exchanger 2 which plays the role of an evaporator in the working condition in summer; the cooled high-concentration solution has stronger moisture absorption capacity again, and then returns to the first humidity conditioning unit 4 for dehumidification, so that the solution completes a dehumidification regeneration cycle.
(2) In the winter cycle shown in fig. 3, the refrigerant cycle process is as follows: compressor 1-first heat exchanger 2-throttle valve 10-second heat exchanger 3-compressor 1. The solution circulation process: the system comprises a first humidity control unit 4, a third heat exchanger 7, a second heat exchanger 3, a second humidity control unit 5, a pump machine 6, a third heat exchanger 7, a compressor 1, a first heat exchanger 2 and a first humidity control unit 4. In the indoor environment in winter, moisture is released in the first humidity conditioning unit 4, and the moisture is brought into the first heat exchanger 2 by indoor return air and is finally sent back to the indoor environment, so that the indoor environment is kept in a warm and non-dry comfortable state; after the first humidity conditioning unit 4 releases moisture, the solution becomes thick and the temperature is reduced, and if the solution can continuously release moisture into the room, the solution needs to be treated to absorb moisture again so as to continuously humidify the room. The concentrated solution coming out of the first humidity conditioning unit 4 along the liquid outlet pipe 8 exchanges heat with the solution coming out of the second humidity conditioning unit 5 along the liquid inlet pipe 9 in the third heat exchanger 7, and the temperature of the solution is reduced. After the solution comes out of the third heat exchanger 7, the solution continues to enter the second heat exchanger 3 of the outdoor unit along the liquid outlet pipe 8 for further cooling, and the temperature continues to be reduced. The solution with low temperature and high concentration has stronger water absorption, so the low-temperature concentrated solution coming out of the second heat exchanger 3 which plays the role of an evaporator in winter working conditions can absorb moisture in outdoor air in the second humidity conditioning unit 5, the water content of the solution is increased, and the concentration is lowered; the low-temperature low-concentration solution flows through the compressor 1 and the first heat exchanger 2 which plays a role of a condenser in winter in the indoor unit to be heated, the heated dilute solution finally enters the first humidifying unit 4 to humidify indoor return air, and at this time, the solution completes a humidifying regeneration cycle.
In addition, under the condition of the dehumidification working condition in summer, the heating by the compressor is carried out only under the premise of the operation of the air-conditioning refrigerant circulating system, for places with plum rain such as Shanghai and Nanjing, the dehumidification efficiency can be changed only by changing the operation speed of the pump 6 under the condition of not changing the indoor temperature, so in order to improve the dehumidification performance, the dehumidification device is additionally provided with the temperature control part 11 in the dehumidification loop, the heating end 12 of the temperature control part 11 is arranged on the liquid outlet pipeline 8 between the third heat exchanger 7 and the second humidity conditioning unit 5, and the refrigerating end 13 of the temperature control part 11 is arranged on the liquid inlet pipeline 9 between the third heat exchanger 7 and the first humidity conditioning unit 4.
