The installation steps of the air to water heat pump heating system are generally as follows: site investigation, determination of the installation position of the heat pump machine – the basis for making the heat pump unit equipment – placement of the heat pump machine adjustment position – connection of the water system – connection of the circuit system – water pressure test – machine test run – insulation of the pipe. Therefore, the following points should be noted during installation:
Installation of heat pump unit.
The air source heat pump unit can be installed on the ground, roof or wall. If installed on the ground or wall, the distance between the heat pump and the surrounding walls or other obstructions should not be too small, and the heat pump foundation should be firm and solid; If it is installed on the roof, the bearing capacity of the roof should be considered. It is better to install it on the building column or bearing beam.
In addition, shock absorption device shall be set between the main engine and the foundation. The rigid pipe connecting the main engine shall adopt spring shock absorption support to prevent the pipeline from transmitting vibration to the building structure. When placing and adjusting the main engine, it is also necessary to ensure that it is stable. If it is uneven, it is likely to cause poor condensate discharge, and even lead to ice in the water receiving tray in severe cold weather, thus blocking the air inlet of the fins.
Electrical installation and line laying
The control box of the heat pump system should be installed in a place where it is easy to operate, and the distribution box should be installed indoors, with convenient maintenance; The power line between the distribution box and the heat pump heat pump should be protected by steel pipes, especially not touched by children; Three-hole sockets shall be used for power sockets, which shall be kept dry and waterproof; The capacity of the power socket shall meet the current power requirements of the heat pump .
System flushing and pressurization
After installation, the water flow must not pass through the heat pump heat pump , hot water tank and terminal equipment when flushing the system to avoid damage. When flushing the system, remember to open the exhaust valve, fill the water while venting, and then open the water pump to run when the system is full. During the pressure test, the test pressure and pressure reduction must meet the design requirements.
Rain and snow protection measures for equipment
Generally, the heat pump products with side air outlet are relatively less affected by rain and snow, while the heat pump products with top air outlet are better equipped with a snow shield to prevent the snow from accumulating on the main fan blades and causing the main motor to be stuck and burned when the equipment is stopped. In addition, the equipment must be installed horizontally, otherwise the rainwater cannot be discharged quickly after entering the equipment, which is easy to cause serious water accumulation in the equipment. At the same time, it should be noted that the heat absorption and heat dissipation of the heat exchanger of the main engine must not be obstructed when installing the rain-proof shed or snow-proof wind shield.
Summary
With the increasing popularity of air energy heat pump and the increasing number of users, people have more and more knowledge of air energy heat pump, and major businesses have more and more experience in the installation of heat pump equipment. Therefore, when we have the use demand of air energy heat pump, we need to pay attention to the selection of air energy heat pump units and the inspection of the installation company, which is very important for the later use and maintenance.
