What maintenance methods are installed for water source heat pump units

Release Time：2021-07-21

Compared with the installation of traditional central air conditioning system, the water source heat pump unit system costs more per square meter of construction area, and because the installation of the water source heat pump unit system involves specific factors such as on-site investigation and pipeline burying, due to different construction sites selected, different ways of burying pipelines will also lead to increased costs, management and maintenance costs: the advantage of lower cost water source heat pump unit system is that the later maintenance is very simple, because the system itself is basically fully automatic operation, the pipeline is buried in the ground, so the probability of failure is very small, a set of equipment of the system has a long service life.
Before the installation of the water source heat pump, joint review of drawings and technical disclosure shall be carried out, and materials shall be selected for construction in strict accordance with the design requirements. The installation and insulation of the air conditioning water system pipeline shall be guided by professional design and the corresponding provisions of the installation specification shall be implemented. The connection between the water pump and the system water pipe and the unit in the system water pipe shall be connected by shock-proof soft joints. At the same time, the pipeline and water pump shall be provided with the support to prevent the unit from being stressed, the external water system of the water source heat pump unit must be equipped with filters, water treaters, check valves, drain valves, expansion tanks, etc.
The discharge water of water source heat pump unit is generally better than that of surface water, and there is often potential energy that can be used. Comprehensive utilization of water source heat pump should be considered. When comprehensive utilization is carried out, the water quality standard requirements of corresponding use should be met, and water balance calculation should be carried out to make all or part of it be used for greening and road watering in the project planning area and nearby areas, the multi-use of surface water source heat pump discharge water can be combined with rainwater comprehensive utilization and community wastewater reuse facilities.
Water source heat pump units have certain requirements on the water quality of the water source. If the water quality fails to meet the requirements, it will cause harm to the valves, the host and its accessories, especially to the plate heat exchanger used by most heat pump manufacturers, thus affecting the operation of the system. Water source heat pump can usually take some treatment measures such as setting up a decontamination device and an electronic descaling device, or several layers of filtering devices are installed in the intake well to reduce the diameter of sand and dust particles contained in the well water, so as to meet the water quality requirements of the unit.
Generally speaking, water source quality is not the main factor affecting the application of water source heat pump units. Water source heat pump includes heat pump and water tank. The characteristic is that there is a circulating pump between the heat pump and the water tank. The heat pump is connected with the water tank through a connecting pipe. The heat pump is equipped with a small water tank and a coil in the small water tank. The water tank is equipped with a temperature control probe and a water gauge and a water inlet pipe.
