技术领域technical field
本发明涉及热泵运行防结霜，结合热泵制取冷热水的地板辐射空调系统，溶液除湿，温湿度独立控制空调技术领域。The invention relates to the anti-frosting of heat pump operation, the floor radiation air-conditioning system combined with heat pump to produce cold and hot water, solution dehumidification, and the technical field of air-conditioning with independent temperature and humidity control.
背景技术Background technique
我国夏热冬冷地区，气候特征比较特殊，夏季高温高湿，冬季阴冷潮湿。而夏热冬冷地区经济活跃，空调需求量高，气候的特殊性造成该地区的空调能耗较高。The hot summer and cold winter regions in my country have special climate characteristics, with high temperature and high humidity in summer and cold and humid winter. In regions with hot summer and cold winter, the economy is active and the demand for air conditioners is high. The particularity of the climate results in high energy consumption of air conditioners in this area.
夏季空调制冷过程中，除湿成了能耗的大块。传统的冷凝除湿，是通过将空气温度冷却到露点温度以下，以除去空气当中的水蒸气。此种方法所需制冷剂温度较低，造成压缩机耗能较高。溶液除湿通过直接与空气接触以除去空气中的水蒸气，因此大大的节约了能源，但除湿过程当中伴随着汽化潜热的释放，造成溶液的除湿性能降低，所以往往在除湿过程中配合其他冷却装置以维持除湿液的温度，另外溶液除湿需要专门的装置进行溶液再生，以满足除湿过程溶液浓度，由此造成了系统的复杂度增大。冬季制热过程中，传统空调由于蒸发器侧空气温度较低，蒸发器表面容易结霜，空调的制热性能大大降低，因此不得不进行除霜处理，由此造成了能源的浪费。During the cooling process of air conditioners in summer, dehumidification has become a large part of energy consumption. Traditional condensation dehumidification is to remove water vapor in the air by cooling the air temperature below the dew point temperature. This method requires a lower temperature of the refrigerant, resulting in higher energy consumption of the compressor. The dehumidification of the solution removes the water vapor in the air by directly contacting with the air, thus greatly saving energy, but the dehumidification process is accompanied by the release of the latent heat of vaporization, which reduces the dehumidification performance of the solution, so it is often used in conjunction with other cooling devices during the dehumidification process In order to maintain the temperature of the dehumidification solution, in addition, solution dehumidification requires a special device for solution regeneration to meet the solution concentration during the dehumidification process, which increases the complexity of the system. During the heating process in winter, due to the low air temperature on the evaporator side of the traditional air conditioner, frost is easy to form on the surface of the evaporator, and the heating performance of the air conditioner is greatly reduced. Therefore, defrosting treatment has to be performed, resulting in a waste of energy.
采用外表面蒸发式溶液除湿，除湿过程无需另外配备冷却装置，其将蒸发冷却与除湿相结合，在除湿过程维持除湿剂的除湿性能。将外表面蒸发式溶液除湿与热泵相结合，夏季热泵冷凝器对溶液进行再生，冬季溶液防止热泵蒸发器结霜。系统在夏/冬季为室内提供高温冷水/低温热水进行地板辐射制冷/采暖。不仅为室内空间提供舒适的温湿度环境，还大大得降低了空调的能耗。The external surface evaporative solution is used for dehumidification. The dehumidification process does not need to be equipped with an additional cooling device. It combines evaporative cooling and dehumidification to maintain the dehumidification performance of the desiccant during the dehumidification process. The outer surface evaporative solution dehumidification is combined with the heat pump, the heat pump condenser regenerates the solution in summer, and the solution prevents the heat pump evaporator from frosting in winter. In summer/winter, the system provides high temperature cold water/low temperature hot water for floor radiant cooling/heating. It not only provides a comfortable temperature and humidity environment for the indoor space, but also greatly reduces the energy consumption of the air conditioner.
发明内容Contents of the invention
技术问题：传统的蒸汽压缩式空调通过冷凝除湿的方式控制空气湿度，极大的浪费了能源，在制冷过程当中往往不能同时精确控制湿度，导致室内环境舒适度大大降低。空气源热泵冬季制热过程中，在室外空气温度较低时容易结霜，导致系统制热性能大大降低，从而必须对蒸发器进行除霜处理，进一步加大了能耗。溶液除湿过程中伴随着汽化潜热的释放，导致溶液温度升高，这将大大的降低了溶液的除湿性能。传统的溶液除湿装置大多为绝热型，少数内冷型除湿装置虽然除湿效果优于绝热型装置，但需另外配备一套冷却装置，加大了除湿系统的复杂度。本专利将外表面蒸发式溶液除湿装置和热泵相结合，为室内地板辐射系统提供冷热水的同时，对室内空气进行湿度控制，将温湿度独立处理，降低空调能耗，提高室内环境的舒适度。Technical problem: Traditional vapor compression air conditioners control air humidity through condensation and dehumidification, which greatly wastes energy. During the cooling process, it is often impossible to accurately control humidity at the same time, resulting in a greatly reduced indoor environment comfort. During the heating process of the air source heat pump in winter, it is easy to frost when the outdoor air temperature is low, resulting in a greatly reduced heating performance of the system, so the evaporator must be defrosted, which further increases energy consumption. During the dehumidification process of the solution, the latent heat of vaporization is released, resulting in an increase in the temperature of the solution, which will greatly reduce the dehumidification performance of the solution. Most of the traditional solution dehumidification devices are adiabatic. Although the dehumidification effect of a few internal cooling dehumidification devices is better than that of adiabatic devices, an additional cooling device is required, which increases the complexity of the dehumidification system. This patent combines the external surface evaporative solution dehumidification device with the heat pump to provide cold and hot water for the indoor floor radiation system, and at the same time control the humidity of the indoor air, independently process the temperature and humidity, reduce the energy consumption of the air conditioner, and improve the comfort of the indoor environment Spend.
技术方案：本发明的一种结合热泵与溶液除湿的温湿度独立控制系统包括冷热水回路、空气回路、制冷剂回路、溶液回路及蒸发冷却回路。Technical solution: An independent temperature and humidity control system combining heat pump and solution dehumidification of the present invention includes a cold and hot water circuit, an air circuit, a refrigerant circuit, a solution circuit and an evaporative cooling circuit.

The dehumidified air is sent back to the room through the action of the third fan. In winter, part of the fresh air and the return air from the room are also mixed and sent to the dehumidifier. At this time, the outside of the dehumidifier is closed, and the whole device is equivalent to heat insulation. The dehumidifier is concentrated and regenerated in the dehumidifier, and water vapor is released into the air. Humidification, the humidified air is sent into the room through the third fan.
制冷剂回路主要由溶液式热质交换器、四通换向阀、压缩机及热交换器组成。夏季工况下，热交换器为蒸发器，热交换器出来的制冷剂经过四通换向阀流向压缩机，之后流进冷凝器溶液式热质交换器中，制冷剂与铜管外的除湿剂进行显热换热，后经过膨胀阀降压后流向热质交换器中。冬季工况下，热交换器为冷凝器，在热交换器中，制冷剂给管外水进行加热，后流出热交换器，通过膨胀阀后，进入蒸发器溶液式热质交换器中，制冷剂吸收铜管外除湿剂的热量后汽化，之后通过四通换向阀流向压缩机，经压缩机加压作用后再回到热交换器当中。The refrigerant circuit is mainly composed of a solution heat-mass exchanger, a four-way reversing valve, a compressor and a heat exchanger. In summer working conditions, the heat exchanger is an evaporator, and the refrigerant coming out of the heat exchanger flows to the compressor through the four-way reversing valve, and then flows into the condenser solution-type heat-mass exchanger. The refrigerant and the dehumidification outside the copper tube The agent performs sensible heat exchange, and then flows into the heat-mass exchanger after being depressurized by the expansion valve. In winter working conditions, the heat exchanger is a condenser. In the heat exchanger, the refrigerant heats the water outside the tube, and then flows out of the heat exchanger. After passing through the expansion valve, it enters the evaporator solution heat-mass exchanger for refrigeration. The dehumidifier absorbs the heat of the dehumidifier outside the copper tube and vaporizes, then flows to the compressor through the four-way reversing valve, and returns to the heat exchanger after being pressurized by the compressor.
溶液回路主要由第一溶液泵、溶液热回收器、溶液-水换热器、外表面蒸发式溶液除湿器及第二溶液泵等组成。夏季工况下，浓溶液在外表面蒸发器中除湿后变成稀溶液，经过第二溶液泵及溶液热回收器后流入溶液式热质交换器中进行浓缩再生，在溶液式热质交换器中，稀溶液被热泵冷凝器加热，除湿剂表面水蒸气分压力升高，水蒸气进入空气中由风机排出，以此完成溶液再生过程。冬季工况下，稀溶液经第一溶液泵及溶液热回收器，在溶液-水换热器中被热水加热，之后进入外表面蒸发式溶液除湿器中，向流入的空气中释放水蒸气，完成溶液再生过程。再生后的浓溶液经过第二溶液泵及溶液热回收器进入溶液式热质交换器中，除湿剂吸收空气当中的水蒸气释放汽化潜热被热泵蒸发器中的制冷剂吸收，另外由于溶液凝固点较低，即使环境空气温度较低时，热泵都能持续运行，有效的解决了传统热泵冬季蒸发器结霜的问题。The solution circuit is mainly composed of the first solution pump, the solution heat recovery device, the solution-water heat exchanger, the outer surface evaporative solution dehumidifier and the second solution pump. In summer working conditions, the concentrated solution becomes a dilute solution after being dehumidified in the outer surface evaporator, and then flows into the solution-type heat-mass exchanger for concentrated regeneration after passing through the second solution pump and solution heat recovery device. , the dilute solution is heated by the heat pump condenser, the partial pressure of water vapor on the surface of the desiccant increases, and the water vapor enters the air and is discharged by the fan, thereby completing the solution regeneration process. In winter working conditions, the dilute solution passes through the first solution pump and solution heat recovery device, is heated by hot water in the solution-water heat exchanger, and then enters the outer surface evaporative solution dehumidifier to release water vapor into the inflowing air , to complete the solution regeneration process. The regenerated concentrated solution enters the solution-type heat-mass exchanger through the second solution pump and the solution heat recovery device. The desiccant absorbs the water vapor in the air and releases the latent heat of vaporization, which is absorbed by the refrigerant in the heat pump evaporator. Low, even when the ambient air temperature is low, the heat pump can continue to run, which effectively solves the problem of frosting on the evaporator of traditional heat pumps in winter.
蒸发冷却回路主要由水喷淋装置、第二风机、第一水泵等组成，在外表面蒸发式溶液除湿器外部水盘中的水经过第一水泵流向水喷淋装置后喷出到除湿管及肋片表面，环境空气经过第二风机的作用流经除湿管及肋片外表面进行蒸发冷却，外表面的水蒸发吸收除湿管内的热量，之后排到环境中。The evaporative cooling circuit is mainly composed of a water spray device, a second fan, and a first water pump. The water in the external water pan of the evaporative solution dehumidifier on the outer surface flows to the water spray device through the first water pump and then is sprayed to the dehumidification pipe and ribs. The ambient air flows through the dehumidification pipe and the outer surface of the fins for evaporative cooling through the action of the second fan. The water on the outer surface evaporates and absorbs the heat in the dehumidification pipe, and then is discharged into the environment.
