Air source heat pump design and construction attention!

空气源热泵机组是通过与空气中的能量进行交换来为室内制取热量，所以空气源热泵主机一定安装在空气畅通的场所，不宜安装在狭小的天井或者周围有围挡的地方。主要以供热为主的空气源热泵主机宜安装在向阳的场所。空气源热泵主机安装的平台或场所一定要有检修的空间。空气源热泵系统耗电量较大，尤其安装电辅热时，电量还会增加，所以在设计时一定要注意电容量是否满足。空气源热泵主机水泵外置时，热泵主机一定要与水泵具有连锁控制，不能孤铜钟 一次性止血带 标志桩模具 钢丝轮 流水槽模具 防撞墙模具 检查井钢模具 不锈钢铸件 模锻件立运行。

Air source heat pump units are exchanged with the energy in the air to make heat for indoor heat, so the main engine of the air source heat pump must be installed in the place where the air is unimpeded, and it is not suitable to be installed in the narrow patio or around the enclosure. The main source of heat supply is the air source heat pump, which should be installed in the sunny place. There must be room for maintenance for the platform or place installed by the host of the air source heat pump. The air source heat pump system has a large power consumption, especially when the auxiliary heating is installed, so the power consumption will increase. So we must pay attention to the capacitance in design. When the main pump of the air source heat pump is placed outside, the heat pump mainframe must have chain control with the pump and can not operate in isolation.

2、空气源热泵制热量与建筑负荷的匹配

2. Match between heat source of air source heat pump and building load.

室内舒适度的维持，主要是空气源热泵主机的制热量要与建筑的热负荷匹配，同时与末端设备的形式和总散热量有关。建筑热负荷决定了热泵主机的选型，在常规大型建筑主机选型时，一般会考虑小于1的同时使用系数，对于面积在100m2的居民建筑，不建议考虑同时使用系数，如果条件允许，建议热泵主机按照建筑热负荷的110%~120%选择。另外，热泵主机的选型还与末端设备的选型有关，如果末端设备是散热器，不建议热泵主机选小;如果末端设备是风机盘管，热泵主机可以适当选小，建议不宜小于建筑热负荷的85%。空气源热泵主机的选择相对复杂，一定要结合建筑的保温情况、结构类型、采暖系统的使用情况以及应用场所的室外环境有关。

The maintenance of indoor comfort is mainly that the heat production of the main engine of the air source heat pump should match the heat load of the building, and it is related to the form of the terminal equipment and the total dissipated heat. The heat load of the building determines the type selection of the main engine of the heat pump. In the selection of the conventional large building host, the coefficient less than 1 is considered at the same time. For the residential buildings in the area of 100m2, the use coefficient is not considered. If the conditions are allowed, it is suggested that the heat pump host be selected according to the 110%~120% of the construction heat load. In addition, the type selection of the heat pump host is related to the type selection of the terminal equipment. If the terminal equipment is a radiator, it is not recommended that the main engine of the heat pump be selected small. If the terminal device is a fan coil, the heat pump host can be selected appropriately, and the suggestion should not be less than 85% of the heat load of the building. The selection of the main engine of the air source heat pump is relatively complex, and it must be related to the thermal insulation of the building, the type of structure, the use of heating system and the outdoor environment of the application place.
