Selection of the main points:
1. The main control parameters of Heat Pump Water To Water Scroll Small Chiller is refrigeration performance coefficient, rated cooling capacity, input power and refrigerant type, etc.
2. The selection of water chiller should be considered according to the cooling load and use.
3. When selecting chiller, the unit with higher performance coefficient value should be given priority. According to statistics, the running time of general chiller under 100% load is less than 1/4 of the total running time. The operating time proportion of 100%, 75%, 50% and 25% load in the total operating time is approximately 2.3%, 41.5%, 46.1% and 10.1%. Therefore, in the selection of water chiller should be given priority to the efficiency curve of the relatively flat model. At the same time, the adjustment range of chiller load should be considered in the design selection.
4. When selecting Heat Pump Water To Water Scroll Small Chiller, pay attention to the conditions of nominal working conditions. The actual cooling capacity of the chiller is related to the following factors:
A) Outlet temperature and flow rate of cold water;
B) Inlet temperature, flow rate and fouling coefficient of cooling water.
5. When selecting the chiller, attention should be paid to the normal working range of this type of unit, mainly because the current limit of the main motor is the current value of the shaft power under the nominal working condition.

Key points of Construction and installation:
1. Vibration isolation and sound suppression measures should be considered in the installation of chiller. When installed outdoors, electrical control equipment and control cabinet should be placed indoors. The installation position of the control cabinet should be able to effectively avoid dampness and even condensation in the cabinet.
2. The concrete foundation of the chiller shall be flat, and when installed on the shock absorber, the pre-compression amount of each shock absorber shall be uniform and the deviation shall be less than 2mm.
3. The pipes connecting the water chiller shall be provided with flexible joints, and the weight of the system pipes shall not be supported by the water chiller.
4. The hoisting point of the chiller shall be adopted. It is forbidden to bundle the hoisting rope on the equipment at will
