在其中一个实施例中，参考图3所示，为另一个具体实施例中空气源热泵机组的控制方法的流程示意图。所述空气源热泵机组的控制方法包括如下步骤。首先，根据项目建筑情况，确定建筑负荷计算方法，可以计算出建筑的逐时负荷。具体的，建筑负荷计算方法可以是指标估算法(折算到建筑物中每平方空调面积上空调设备所需要提供的热负荷)。可选地，建筑负荷计算方法，还可以是将建筑物作为一个整体，根据项目所在地的供暖季气象参数，对建筑物各逐时项负荷进行附加计算，而得到一组逐时建筑采暖负荷数据，再根据逐时建筑采暖负荷数据进行设备选型。In one embodiment, refer to FIG. 3 , which is a schematic flowchart of a control method for an air source heat pump unit in another specific embodiment. The control method of the air source heat pump unit includes the following steps. First of all, according to the construction situation of the project, the calculation method of the building load can be determined, and the hourly load of the building can be calculated. Specifically, the building load calculation method may be the index estimation method (converted to the heat load that the air-conditioning equipment needs to provide per square air-conditioning area in the building). Optionally, the building load calculation method can also be to take the building as a whole, and according to the meteorological parameters of the heating season at the location of the project, additionally calculate the hourly item load of the building, and obtain a set of hourly building heating load data , and then select equipment according to the hourly building heating load data.
其次，建立预设供水温度模型库。具体地，在得到逐时建筑采暖负荷后，由公式Q＝G×Δh可知，Q代表热量，G代表送风量，Δh代表热能差，在末端设备送风量、建筑采暖逐时负荷确定的情况下，可计算逐时空调处理的热能差，从而得到送风点参数(温 湿度、焓值)。考虑末端风盘换热效率的衰减性，取末端出水温度略高于送风点参数0.5～1℃，在已知各逐时工况点的送风点参数，即可确定该工况下***(允许)的最低回水温度，即送风温度+(0.5～1℃)。已知***供回水温差，已知回水温度，即可确定该工况下(室外环境温度下)***供水温度。从而可以确定供水温度模型库。Second, establish a preset water supply temperature model library. Specifically, after obtaining the hourly building heating load, it can be known from the formula Q=G×Δh that Q represents heat, G represents the air supply volume, and Δh represents the heat energy difference. The air supply volume of terminal equipment and the hourly load of building heating are determined In some cases, the heat energy difference of hourly air-conditioning treatment can be calculated to obtain the air supply point parameters (temperature and humidity, enthalpy). Considering the attenuation of the heat exchange efficiency of the terminal wind disk, the temperature of the outlet water at the terminal is slightly higher than the air supply point parameter by 0.5-1°C, and the air supply point parameters of each hourly working condition point are known, and the system under this working condition can be determined. (Allowed) the lowest return water temperature, that is, the air supply temperature + (0.5 ~ 1 ℃). Knowing the temperature difference between the supply and return water of the system and the return water temperature, the system supply water temperature under this working condition (under the outdoor ambient temperature) can be determined. Thus, the supply water temperature model library can be determined.
进一步地，设定室内初始温度值，设定水温控制周期。具体地，在设置室内温度值后，空气源热泵机组开始工作。在空气源热泵机组工作过程中，可以以一定周期，获取空气源热泵机组工作过程中的当前室内温度以及当前室外气象参数，具体的，可以只获取当前室内温度，也可以只获取当前室外气象参数，还可以既获取当前室内温度，又获取当前室外气象参数。具体的，所述周期可以为30分钟。后续以此周期为控制周期，实现对水温的控制。Further, the initial indoor temperature value is set, and the water temperature control period is set. Specifically, after setting the indoor temperature value, the air source heat pump unit starts to work. During the working process of the air source heat pump unit, the current indoor temperature and the current outdoor meteorological parameters during the working process of the air source heat pump unit can be obtained at a certain period. Specifically, only the current indoor temperature can be obtained, or only the current outdoor meteorological parameters can be obtained. , it is also possible to obtain both the current indoor temperature and the current outdoor meteorological parameters. Specifically, the period may be 30 minutes. Then use this cycle as the control cycle to realize the control of the water temperature.
进一步地，实时监测室外气象参数和室内温度。具体地，根据获取的当前室内温度以及当前室外气象参数，可以判断，空气源热泵机组的末端负荷需求是否发生了变化，当确定末端负荷需求发生变化时，则可以获取目标供水温度。其中，末端负荷需求是指针对任意一个建筑物，在该建筑物中，空气源热泵机组所需要提供的热负荷，目标供水温度是指在可以满足末端负荷需求的情况下，空气源热泵机组的最佳供水温度，预设室内温度是指预先设定的建筑室内的温度，当前室内温度是指实时测得的室内温度，当前室外气象参数是指实时测得的室外气象参数，预设供水温度模型库是由各项逐时数据构成的温度模型库。Further, outdoor weather parameters and indoor temperature are monitored in real time. Specifically, according to the obtained current indoor temperature and current outdoor meteorological parameters, it can be judged whether the terminal load demand of the air source heat pump unit has changed, and when it is determined that the terminal load demand has changed, the target water supply temperature can be obtained. Among them, the terminal load demand refers to the heat load that the air source heat pump unit needs to provide for any building, and the target water supply temperature refers to the air source heat pump unit that can meet the terminal load demand. The optimal water supply temperature, the preset indoor temperature refers to the preset indoor temperature of the building, the current indoor temperature refers to the real-time measured indoor temperature, the current outdoor meteorological parameters refer to the real-time measured outdoor meteorological parameters, and the preset water supply temperature The model library is a temperature model library composed of various hourly data.
最后，可以根据目标供水温度调节空气源热泵机组的供水温度。具体的，当预设室内温度大于当前室内温度，且供水温度与预定温度步长之和小于或等于所述目标供水温度，则将所述空气源热泵机组的供水温度增加预定温度步长；若预设室内温度大于当前室内温度，且供水温度与预定温度步长之和大于所述目标供水温度，则直接将空气源热泵机组的供水温度调整为所述目标供水温度；若预设室内温度小于当前室内温度，且供水温度与预定温度步长之差大于或等于所述目标供水温度，则将所述空气源热泵机组的供水温度减小预定温度步长；若预设室内温度小于当前室内温度，且供水温度与预定温度步长之差小于所述目标供水温度，则直接将空气源热泵机组的供水温度调整为所述目标供水温度。Finally, the water supply temperature of the air source heat pump unit can be adjusted according to the target water supply temperature. Specifically, when the preset indoor temperature is greater than the current indoor temperature, and the sum of the water supply temperature and the predetermined temperature step is less than or equal to the target water supply temperature, the water supply temperature of the air source heat pump unit is increased by the predetermined temperature step; if If the preset indoor temperature is greater than the current indoor temperature, and the sum of the water supply temperature and the predetermined temperature step is greater than the target water supply temperature, then directly adjust the water supply temperature of the air source heat pump unit to the target water supply temperature; if the preset indoor temperature is less than The current indoor temperature, and the difference between the water supply temperature and the predetermined temperature step is greater than or equal to the target water supply temperature, then reduce the water supply temperature of the air source heat pump unit by a predetermined temperature step; if the preset indoor temperature is less than the current indoor temperature , and the difference between the water supply temperature and the predetermined temperature step is smaller than the target water supply temperature, then directly adjust the water supply temperature of the air source heat pump unit to the target water supply temperature.
