1. Installation steps of air source heat pump heating system
This article focuses on analyzing the installation precautions for home machines. By searching for relevant information, it can be seen that the installation of an air source heat pump heating system can be roughly divided into the following steps:
(1) Before installing the host, it is necessary to survey the installation site, select and determine the installation location of the host.
(2) To make the basis 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 to 20cm.
(3) Place the host and adjust the position of the unit to ensure that the host is placed stably.
(4) Connection to the water system, mainly the connection of water pumps, valve bodies, filters and other components between the host and the water tank.
(5) Connect the circuit system, mainly connecting the power cord, water pump, solenoid valve , water temperature sensor , pressure switch , etc. according to the wiring diagram requirements.
(6) Test the pressure of the waterway and check whether there is any leakage in the pipeline connection.
(7) Trial run the machine and check various parameters of the system.
(8) Pipeline insulation, such as using rubber and plastic insulation material to insulate the waterway system.
2. "Rules" for the installation of air source heat pump heating systems
Mastering the installation steps is just mastering the basic installation knowledge. What really determines the quality of the installation are the many installation details. Every step of the installation has "rules" to follow. Likewise, It requires a firm grasp by the installer. There are many "rules" for the installation of air source heat pump hosts. If the installers understand them, it will be of great benefit to improve the installation quality.
1. Pre-installation survey work is necessary
Before installing the host, it is very necessary to survey the installation site.
"Beijing's 2016 Guiding Opinions on the Promotion of "Coal-to-Clean Energy and Coal-to-Coal Reduction" in Rural Areas Villages clearly states: " air source heat pump supply companies must enter households for on-site inspections and propose heating design plans and various After the relevant indicators are satisfied, recognized and signed by the residents, the enterprise and the user can sign a heating equipment supply and installation contract. ”
2. The host has high requirements on the installation space environment
Air source heat pumps have high requirements on the installation space environment. Different locations have different requirements.
The air source heat pump host can be installed on the ground, roof or wall. If installed on the ground or 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. In addition, the equipment foundation must be well prepared;
The equipment is installed on the ground. on the roof, use expansion bolts to fix it; if it is installed on the roof, the load-bearing capacity of the roof must be considered. Roofs that cannot meet the load-bearing requirements are strictly not allowed to be installed. If they can be installed on the roof, pay attention to the direction of the air source heat pump's air outlet. The problem is that the air outlet direction of the main unit is installed with the wind, so that the heat exchange effect of the main unit will be good.
Air source heat pumps must have good heating performance. When installing, the host must be well ventilated. If the ventilation effect is not good, the air intake volume of the equipment cannot be guaranteed, and the air flow is also prone to short circuit, and the heating capacity of the equipment will be significantly reduced, seriously It will cause frequent frosting and defrosting of the equipment, and the equipment will do useless work.
3. It is important to lay a good "foundation"
The foundation of the equipment must be solid and solid. On this basis, the host must be placed and adjusted smoothly, ensure it is installed upright, and be fixed with expansion bolts.
The installation of some hosts is uneven, which makes it difficult to discharge the condensate water of the equipment . Once the condensate water is not discharged smoothly, in severe cold climates, the water tray will inevitably freeze, and long-term accumulation will block the fins. The air enters, causing the heating capacity of the equipment to decrease.In addition, shock-absorbing measures need to be taken between the main machine and the bottom foundation. The rigid pipes connected to the main machine should use spring shock-absorbing brackets to prevent the pipes from transmitting vibrations to the building structure.
4. Take measures to protect the equipment from rain and snow
In the actual installation, you also need to consider issues such as drainage, rain and snowproof, lightning protection, maintenance space and other issues of the host equipment. If these details are not taken into account, it will directly affect Heating effect and service life of air source heat pump heating system.
In terms of protection against rain and snow, air source heat pump products with side discharge are better and are less affected by rain and snow; for air source heat pump products with top discharge, install a snow-proof wind cover to prevent snowflakes when the equipment is shut down. It falls on the fan blades of the main unit and accumulates, causing the motor of the main unit to get stuck and burn out.
For snowy days, there are also enterprise installers who install bottom brackets for the equipment when making the equipment foundation or during construction, thus avoiding snow accumulation problems caused by snowy days. In terms of rain protection, the main thing is to ensure that rainwater can be drained out 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 a rainproof canopy or snowproof windshield is installed to protect the host, care should be taken to ensure that the heat absorption and heat dissipation of the host heat exchanger are not hindered.
The installation of the air source heat pump system is an important link that cannot be ignored. What are the steps of installation and what issues need to be paid attention to during the installation process are what every user should be concerned about and keep in mind.
