Only when the air-source heat pump is installed correctly, better results can be achieved in future use. This article will specifically introduce the installation steps and precautions of the air source heat pump.
If the installation of the air source heat pump is not correct, some problems may occur in the subsequent use, and its performance must not reach the expected effect. Then we need to pay attention to a lot of things during the installation of the air source heat pump. The following are the specific steps and some points of attention.
(1) Before installing the host, it is necessary to survey the installation site, select and determine the installation location of the host.
(2) Make the foundation of the host equipment. If the installation location is determined to be on the ground, cement can be used. The thickness of the cement is about 15cm-20cm.
(3) Place the host and adjust the position of the unit to ensure that the host is placed smoothly.
(4) The connection to the water system is mainly the connection of the water pump, valve body, filter, and other components between the host and the water tank.
(5) Connect the circuit system, mainly connect the power cord, water pump, solenoid valve, water temperature sensor, pressure switch, etc. according to the wiring diagram requirements.
(6) Waterway pressure test, check whether there is water leakage in the pipeline connection.
(7) Test operation of the machine, check the various parameters of the system.
(8) Pipe heat preservation, such as using rubber and plastic heat preservation materials to heat the waterway system.
High installation space environment requirements
Air source heat pumps have high requirements for the installation space environment, and installation in different locations has different requirements.
The air source heat pump host can be installed on the ground, on the roof, or on the wall. If it is installed on the ground or on a wall, in order to ensure that the heat absorption and heat dissipation of the host heat exchanger is not hindered, the distance between the host and the surrounding walls or other obstructions should not be too small, and the equipment foundation should be well established.
The equipment is installed on the ground and fixed with expansion bolts. If it is installed on the roof, the load-bearing capacity of the roof must be considered. The roof that cannot meet the load-bearing requirements is strictly not allowed to be installed. If it can be installed on the roof, pay attention to the direction of the air source heat pump. The wind direction of the host is best to be downwind. Install, so that the heat exchange effect of the host will be better.
The air source heat pump must have good heating performance. When installing, ensure that the main engine is well ventilated, the ventilation effect is not good, the air intake of the equipment is difficult to ensure, the airflow is also easy to short-circuit, and the heating capacity of the equipment will be significantly reduced. It will cause frequent frosting and defrosting of the equipment, and the equipment will perform useless work.
Firm and stable equipment foundation
The foundation of the equipment must be made firm and strong. On this basis, the host must be placed and adjusted smoothly, ensure that it is installed upright, and fixed with expansion bolts.
The installation of some mainframes is uneven, which causes certain difficulties in the discharge of condensate from the equipment. Once the condensate is not discharged smoothly, in severely cold climates, the drain pan will inevitably freeze, and long-term accumulation will block the air intake of the fins. As a result, the heating capacity of the equipment is reduced. In addition, shock absorption measures need to be taken between the main engine and the foundation at the bottom. The rigid pipeline connecting the main engine should use spring shock-absorbing brackets to prevent the pipeline from transmitting vibration to the building structure.
Take measures to prevent rain and snow for the equipment
In the actual installation, it is also necessary to consider the drainage of the host equipment, rain and snow protection, lightning protection, maintenance space, and other issues. If these details are not considered in place, it will directly affect the heating effect and service life of the air source heat pump heating system.
In terms of rain and snow protection, side-vented air source heat pump products will be better, and are less affected by rain and snow; for top-vented air source heat pump products, it is best to install a snow wind cover for them to prevent the equipment from shutting down. Snow fell on the wind blades of the main engine and accumulated, causing the main engine's motor to be stuck and burned out.
For snowy weather, there are also enterprise installers who install bottom brackets on the equipment when making the equipment foundation or during construction, so as to avoid the snow problem caused by snowy weather. In terms of rain protection, it is mainly to ensure that rainwater can be discharged as soon as possible after entering the equipment. This requires that the installation of the equipment must be level to prevent serious water accumulation in the equipment.
In addition, if you install a rain shed or snow wind cover to protect the host, care should be taken to ensure that the heat absorption and heat dissipation of the host heat exchanger is not hindered.
The installation of the air source heat pump system is an important link that cannot be ignored.
