技术领域Technical field
本申请涉及空调设备技术领域，具体涉及一种恒温恒湿空调器。The present application relates to the technical field of air conditioning equipment, and in particular, to a constant temperature and humidity air conditioner.
背景技术Background technique
恒温恒湿空调器是以风冷冷风型单元式空调机为基础的特殊空气调节器。恒温恒湿空调器通过空调器系统进行制冷与制热，向使用场所提供冷量与热量。还包括辅助加热装置和加湿装置，对使用场所空气的温度与湿度进行调节。具体地，当室内温度高于设定温度上偏差时，制冷系统运转。当室内温度低于设定温度下限时，制热系统运行，同时辅助加热装置根据需求进行选择性开启。当室内温度上升至设定温度以上一定偏差时，制热系统和辅助加热装置停止工作，依此循环运转对室内温度进行控制。湿度是通过加湿装置的开停循环使湿度在设定值上下偏差内波动。The constant temperature and humidity air conditioner is a special air conditioner based on air-cooled and cold-air unit air conditioners. The constant temperature and humidity air conditioner performs cooling and heating through the air conditioner system, and provides cold and heat to the place of use. It also includes auxiliary heating devices and humidifiers to adjust the temperature and humidity of the air in the place of use. Specifically, when the indoor temperature is higher than the set temperature, the refrigeration system operates. When the indoor temperature is lower than the lower limit of the set temperature, the heating system is operated, and the auxiliary heating device is selectively turned on according to demand. When the indoor temperature rises to a certain deviation above the set temperature, the heating system and the auxiliary heating device stop working, and the indoor temperature is controlled according to the cycle operation. Humidity is to make the humidity fluctuate within the set value up and down through the on-off cycle of the humidifier.
而相关技术中，恒温恒湿空调器在制热时室外机换热器会结霜，换热器结霜后会使空调系统恶化，因此必须进行除霜处理。然而恒温恒湿空调器作为特种空调器，为了保持室内温度稳定必须持续运行，因此即使室外机换热器在进行除霜，室内机也必须向室内持续提供热风。当恒温恒湿空调器运行除霜时，室内机换热器为蒸发器，蒸发器会对空气进行制冷。因此需要辅助加热装置对冷风加热并将冷风加热为热风吹向室内。由此可见，现有技术中的恒温恒湿空调器在除霜过程会造成严重的能耗浪费。In the related art, when the constant temperature and humidity air conditioner is heating, the outdoor unit heat exchanger will frost, and the frost on the heat exchanger will degrade the air conditioning system, so it must be defrosted. However, as a special air conditioner, a constant temperature and humidity air conditioner must be continuously operated in order to keep the indoor temperature stable. Therefore, even if the outdoor unit heat exchanger is defrosting, the indoor unit must continuously provide hot air to the room. When the constant temperature and humidity air conditioner operates to defrost, the indoor unit heat exchanger is an evaporator, and the evaporator cools the air. Therefore, an auxiliary heating device is required to heat the cold wind and heat the cold wind into hot air to blow into the room. It can be seen that the constant temperature and humidity air conditioner in the prior art will cause serious waste of energy consumption during the defrosting process.
发明内容Summary of the Invention
因此，本申请提供一种恒温恒湿空调器，避免能源浪费，达到节能环保的目的。Therefore, the present application provides a constant temperature and humidity air conditioner to avoid energy waste and achieve the purpose of energy conservation and environmental protection.

室内机壳体，具有进风口、出风口和所述出风口与所述进风口之间的风道；所述室内机换热器设置于所述风道中；以及The indoor unit housing has an air inlet, an air outlet, and an air passage between the air outlet and the air inlet; the indoor unit heat exchanger is disposed in the air passage; and
蓄热装置，设置于所述室内机壳体内，包括在所述循环回路制热模式时储存热量的蓄热部以及与所述蓄热部热交换的换热部，所述换热部与所述室外机换热器的除霜回路相连。The heat storage device is disposed in the indoor unit casing, and includes a heat storage section that stores heat during the heating mode of the circulation circuit, and a heat exchange section that exchanges heat with the heat storage section. The defrosting circuit of the outdoor unit heat exchanger is connected.
本申请提供的一种恒温恒湿空调器，包括设置于室内机壳体的蓄热装置，蓄热装置包括在循环回路制热模式时储存热量的蓄热部以及与蓄热部热交换的换热部，换热部与室外机换热器的除霜回路相连。如此设计，当循环回路在制热模式下，室外机换热器是蒸发器，采用蓄热装置将热能储存一部分，当室外机换热器达到除霜温度点时，循环回路关闭，蓄热装置将储存的一部分热量供室外机换热器除霜使用，达到节能环保的目的。并且此时室内机换热器不会制冷，因此室内温度不会因除霜而降低，避免除霜过程中的能源浪费，除霜能耗大幅度降低。A constant temperature and humidity air conditioner provided by the present application includes a heat storage device provided in an indoor unit casing. The heat storage device includes a heat storage unit that stores heat in a circulation loop heating mode, and a heat exchange unit that exchanges heat with the heat storage unit. The heat part and the heat exchange part are connected with the defrosting circuit of the outdoor unit heat exchanger. In this way, when the circulation loop is in heating mode, the outdoor unit heat exchanger is an evaporator, and a heat storage device is used to store a part of the thermal energy. When the outdoor unit heat exchanger reaches the defrost temperature point, the circulation loop is closed and the heat storage device Part of the stored heat is used for defrosting the outdoor unit heat exchanger to achieve the purpose of energy saving and environmental protection. And at this time, the indoor unit heat exchanger will not be cooled, so the indoor temperature will not be reduced due to defrosting, energy waste during defrosting is avoided, and the energy consumption for defrosting is greatly reduced.
本申请提供的一种恒温恒湿空调器，包括连接在压缩机与室外机换热器之间的热回收换热器。如此设计，当制冷除湿时，制冷除湿的过程会导致温度的降低，加热装置热交换器可以补偿温度，达到恒温除湿的效果。当需要同步加湿时，加湿器喷头会将水喷洒在加热装置使水雾蒸发，达到对室内空气进行加湿的目的。由此可知，热回收换热器针对除湿耗能、制热耗能可替代纯电加热系统，无需额外耗能，达到节能、环保的效果。A constant temperature and humidity air conditioner provided by the present application includes a heat recovery heat exchanger connected between a compressor and an outdoor unit heat exchanger. In this way, when refrigerating and dehumidifying, the process of refrigerating and dehumidifying will cause the temperature to decrease, and the heat exchanger of the heating device can compensate the temperature to achieve the effect of constant temperature dehumidification. When synchronous humidification is needed, the nozzle of the humidifier sprays water on the heating device to evaporate the water mist to achieve the purpose of humidifying the indoor air. It can be known that the heat recovery heat exchanger can replace the pure electric heating system for dehumidification energy consumption and heating energy consumption, without additional energy consumption, and achieving the effects of energy saving and environmental protection.
本申请提供的一种恒温恒湿空调器，其包括新风处理装置，新风处理装置包括与循环回路相连的全热交换器。如此设计，当室内引入新风时，新风通过全热交换器对室外新风温度进行交换，使其达到和室内温度相当，不至于对室内温度造成波动产生额外的耗能，从而达到节能、环保的效果。A constant temperature and humidity air conditioner provided by the present application includes a fresh air processing device, and the fresh air processing device includes a full heat exchanger connected to a circulation circuit. In this way, when fresh air is introduced into the room, the fresh air exchanges the outdoor fresh air temperature through a full heat exchanger, so that it reaches the same temperature as the indoor temperature, so as not to cause additional energy consumption due to fluctuations in the indoor temperature, thereby achieving energy saving and environmental protection .

该恒温恒湿空调器的工作原理为：The working principle of the constant temperature and humidity air conditioner is:
空气从进风口3进入，通过过滤装置4进入风道，与室内机换热器9进行换热。经过热交换的空气从出风口2排出。当制冷除湿时，制冷除湿的过程会导致温度的降低。此时， 热回收换热器可以补偿温度，达到恒温除湿的效果。当室内检测需要同步加湿时，加湿器喷头11会将水喷洒在加热装置7使水雾蒸发，达到对室内空气进行加湿的目的。由此可知，热回收换热器针对除湿耗能、制热耗能可替代纯电加热系统，无需额外耗能，达到节能、环保的效果。The air enters through the air inlet 3 and enters the air passage through the filtering device 4 to perform heat exchange with the indoor unit heat exchanger 9. The heat-exchanged air is discharged from the air outlet 2. When cooling and dehumidifying, the process of cooling and dehumidifying will cause the temperature to decrease. At this time, the heat recovery heat exchanger can compensate the temperature and achieve the effect of constant temperature dehumidification. When synchronous humidification is required for indoor detection, the humidifier nozzle 11 sprays water on the heating device 7 to evaporate the water mist, thereby achieving the purpose of humidifying the indoor air. It can be known that the heat recovery heat exchanger can replace the pure electric heating system for dehumidification energy consumption and heating energy consumption, without additional energy consumption, and achieving the effects of energy saving and environmental protection.
当室内检测室内空气污浊时，新风处理装置5开启进行室内空气置换，达到对室内空气净化的目的。当室内引入新风时，新风通过全热交换器12对新风温度进行交换，使其达到和室内温度相当，不至于对室内温度造成波动产生额外的耗能，从而达到节能、环保的效果。When the indoor air pollution is detected indoors, the fresh air processing device 5 is turned on to perform indoor air replacement to achieve the purpose of purifying the indoor air. When fresh air is introduced into the room, the fresh air exchanges the temperature of the fresh air through the total heat exchanger 12 so that it is equivalent to the indoor temperature and does not cause additional energy consumption caused by fluctuations in the indoor temperature, thereby achieving energy saving and environmental protection effects.
当循环回路在制热模式下，蓄热装置6将一部分热量储存起来。当室外机换热器达到除霜温度点时，循环回路关闭，蓄热装置则将一部分热量供室外机换热器化霜使用，达到节能环保。When the circulation circuit is in the heating mode, the heat storage device 6 stores a part of the heat. When the outdoor unit heat exchanger reaches the defrosting temperature point, the circulation loop is closed, and the heat storage device supplies part of the heat for the outdoor unit heat exchanger to defrost, thereby achieving energy saving and environmental protection.
