Description
技术领域 technical field
本实用新型属制冷机械技术领域，涉及一种风冷冷水机组，更具体说是一种全年制冷的风冷冷水机组。 The utility model belongs to the technical field of refrigeration machinery, and relates to an air-cooled chiller, more specifically an air-cooled chiller for year-round refrigeration.
背景技术 Background technique
当今世界许多大城市面临水资源短缺的问题，而当前社会装机容量很大的水冷空调机组配置的冷却塔却消耗不小比例的水，因而节约水资源减少水浪费无疑是空调业刻不容缓之事。相比水冷制冷机组，风冷机组省去了冷却塔、冷却水泵、管网及其水处理设备，非常适用于水源紧张的地区，可以预见风冷机组的社会需求量将愈来愈大，对风冷制冷机组的要求也会愈来愈高。 Many big cities in the world today are facing the problem of water shortage, but the cooling towers equipped with water-cooled air-conditioning units with a large installed capacity in the current society consume a large proportion of water. Therefore, saving water resources and reducing water waste is undoubtedly an urgent matter for the air-conditioning industry. Compared with water-cooled refrigeration units, air-cooled units save cooling towers, cooling water pumps, pipe networks and water treatment equipment, and are very suitable for areas with water shortages. It can be predicted that the social demand for air-cooled units will increase. The requirements for air-cooled refrigeration units will also become higher and higher.
各种空调***的工作过程其实就是一个能量搬运过程：制冷时把能量搬运出去，制热时把能量搬运过来。由于风冷机组是利用空气来冷却制冷剂的，而环境温度随季节变化很大，而水冷机组的冷却水温度随季节变化要小很多。在要求全年制冷的场合，季节变化对水冷机组的制冷量的影响不大，但对风冷机组来说，环境温度变化与其制冷量有着直接的关系。现有的风冷冷水机组包括压缩机、风冷冷凝器、节流装置、蒸发器、其中风冷冷凝器虽有若干个散热器及冷凝风机组成，但运行时其散热面积大小不作变化，只是依靠运行风机数量变化来改变风量,这种冷却能力的调整是非常有限的,无法适应全年制冷运行的需要,因而造成了能源的浪费和风冷冷水机组运行的不稳定。 The working process of various air-conditioning systems is actually a process of energy transfer: energy is transferred out during cooling, and energy is transferred back during heating. Since the air-cooled unit uses air to cool the refrigerant, the ambient temperature varies greatly with the seasons, while the cooling water temperature of the water-cooled unit varies much less with the seasons. In occasions where cooling is required throughout the year, seasonal changes have little effect on the cooling capacity of water-cooled units, but for air-cooled units, ambient temperature changes have a direct relationship with their cooling capacity. Existing air-cooled chillers include a compressor, an air-cooled condenser, a throttling device, and an evaporator. Although the air-cooled condenser is composed of several radiators and condensing fans, its heat dissipation area does not change during operation. Depending on the number of operating fans to change the air volume, the adjustment of this cooling capacity is very limited and cannot meet the needs of cooling operation throughout the year, resulting in waste of energy and unstable operation of air-cooled chillers.
发明内容 Contents of the invention
本实用新型要解决的技术问题和提出的技术任务是克服现有风冷冷水机组运行不稳定、造成能源浪费的缺陷，提供一种全年制冷风冷冷水机组。 The technical problem to be solved and the technical task proposed by the utility model are to overcome the defects of the existing air-cooled chiller that the operation is unstable and cause energy waste, and to provide a year-round cooling air-cooled chiller.
为此，本实用新型的全年制冷风冷冷水机组，包括连接在循环制冷剂回路中的压缩机、风冷冷凝器、贮液器、节流装置、蒸发器，所述风冷冷凝器包括若干组散热器和由控制器控制的风机，其特征是：它还包括由控制器控制的电磁阀、压力传感器、温度传感器，所述的温度传感器设置在风冷冷水机组运行的环境中，所述的压力传感器安装于压缩机排气管上；所述的各散热器上选择性配置所述的电磁阀。 For this reason, the annual refrigeration air-cooled chiller of the utility model includes a compressor connected in the circulating refrigerant circuit, an air-cooled condenser, a liquid reservoir, a throttling device, and an evaporator, and the air-cooled condenser includes Several groups of radiators and fans controlled by the controller are characterized in that: it also includes a solenoid valve controlled by the controller, a pressure sensor, and a temperature sensor, and the temperature sensor is set in the environment where the air-cooled chiller operates, so The above-mentioned pressure sensor is installed on the exhaust pipe of the compressor; the above-mentioned electromagnetic valve is selectively arranged on each of the above-mentioned radiators.
作为优选技术措施，所述的控制器分别与所述的风机、电磁阀、温度传感器、压力传感器信号连接。 As a preferred technical measure, the controller is respectively connected with the fan, solenoid valve, temperature sensor and pressure sensor in signal connection.
作为优选技术措施，所述的电磁阀接在对应散热器的出口处。 As a preferred technical measure, the solenoid valve is connected to the outlet of the corresponding radiator.
本实用新型由于若干个散热器上分别具有独立的风机和电磁阀，而且风机的电机采用变频电机，同时在风冷冷水机组运行的环境中设置温度传感器及在排气管路上设置了排气压力传感器，机组制冷运行时，控制器根据采集的温度信号与压力信号分别调节冷凝器各散热器出口管路上的电磁阀和风机，通过控制电磁阀和风机的开启、调节风机转速，控制冷凝器换热量。因此本实用新型的全年制冷的风冷冷水机组的风冷冷凝器能随环境温度变化而调节，达到节约能源的效果，并且使风冷冷水机组运行稳定。在夏季机组运行时，由于环境温度高，冷凝器与环境温度的温差较小，电磁阀和风机需全部开启从而为机组提供最佳的散热条件，实现机组高效运行。在冬季运行时，由于气温低，冷凝器与环境温度的温差较大，电磁阀和风机可部分开启，通过减小冷凝换热面积和空气流速，来控制冷凝能力与制冷***需求相适应，实现全年制冷的目的。 Since the utility model has independent fans and electromagnetic valves on several radiators, and the motors of the fans adopt variable frequency motors, at the same time, temperature sensors are set in the environment where the air-cooled chiller operates and exhaust pressure is set on the exhaust pipeline. sensor, when the unit is in cooling operation, the controller adjusts the solenoid valve and fan on the outlet pipeline of each radiator of the condenser respectively according to the collected temperature signal and pressure signal. heat. Therefore, the air-cooled condenser of the year-round air-cooled chiller of the utility model can be adjusted with the change of ambient temperature to achieve the effect of saving energy and make the air-cooled chiller run stably. When the unit is running in summer, due to the high ambient temperature and the small temperature difference between the condenser and the ambient temperature, the solenoid valve and fan must be fully turned on to provide the unit with the best heat dissipation conditions and achieve efficient operation of the unit. During winter operation, due to the low temperature and the large temperature difference between the condenser and the ambient temperature, the solenoid valve and the fan can be partially opened to control the condensing capacity to meet the needs of the refrigeration system by reducing the condensing heat exchange area and air flow rate. Year-round cooling purposes.

下面简单介绍实用新型的全年制冷的风冷冷水机组的工作原理，压缩机1吸入来自蒸发器4的低温低压制冷剂蒸气，对低温低压的蒸汽压缩作功后变成高温高压的过热蒸气。然后，高压高温的制冷剂蒸气进入风冷冷凝器2，通过风机10的强制通风，与温度较低的环境空气进行热交换，将冷凝过程中所释放的热量传递给空气，使气态制冷剂凝结为高压液体。高压液体经节流装置3，节流降压后变成低温低压且液体含量较高的气液两相混合物，这些气液两相混合物进入蒸发器4。在蒸发器4内，低温低压的制冷剂将与温度相对较高的冷冻水发生热量交换，制冷剂液体将发生气化，吸收冷冻水的热量后变成低温低压制冷剂蒸气，从而降低了冷冻水的温度达到制冷目的。气化后的制冷剂蒸气将被吸入压缩机，如此往复循环。
