An air source heat pump is an economical and applicable energy-saving device, which is widely used in various heating systems, such as air conditioning systems, water heater groups, etc. It is liked by many consumers for its safe performance, energy-saving, and environmental protection utility. However, users should note that the installation of an air source heat pump is very important, if it is not properly installed will affect the operating efficiency and heating effect of the heat pump system. Next, let's take a look at the installation requirements of each component of the air source heat pump system and the installation steps of the system.
Here is the content list:
Installation requirements for each component of the air source heat pump system
Air source heat pump system overall installation steps
1, Installation requirements of the main unit
(1) The installation requirements of the host of the air source heat pump are the same as the installation requirements of the outdoor unit of the air conditioner. Can be installed on the external wall, roof, balcony, and ground.
(2) The distance between the host and the water storage tank shall not be greater than 5 meters, the standard configuration of 3 meters.
(3) The distance between the host and the surrounding walls or other coverings can not be too small.
(4) The host should be installed on a solid foundation, ensure upright installation, and fixed with ground bolts.
2, Installation requirements of the water storage tank
(1) The water storage tank can be installed outdoors with the air source heat pump outdoor unit, such as on balconies, roofs hang, or installed indoors. The water storage tank must be installed on the ground, and the installation of a solid foundation, must bear a weight of 500kg, and not hang on the wall.
(2) Near the storage tank, as well as the water pipe and hot water pipe interface with a valve.
(3) The tank hot water outlet safety valve pressure relief port dripping is the unloading phenomenon, to protect the role of a drain hose.
3, Water connection requirements
(1) Connect the water outlet interface with the PP-R pipe to the water storage tank according to the design drawings and seal it with raw material.
(2) One end of the check valve is connected to the tap water pipe, and the other end is connected to the water inlet receiver of the water storage tank.
(3) Open the tap water inlet valve, and open the hot water pipe in the outlet water. Begin to fill until the water out of the water overflow when the water is filled, close the water. Water storage leak detection, to ensure that no water leakage.
4, The heating pipe connection requirements
(1) In the water storage tank and heat pump between the host wall drill a Ф70 pipe hole, the hole should be slightly outward sloping. Connect the pipe and a certain length of cable wrapped with plastic ties, through the pipe hole, both sides of the sheath through the wall.
(2) Remove the cap on the head of the water tank thick and thin connection pipe, respectively, the thick and thin connection pipe screwed to the storage tank thick and thin connection pipe on the connector, tighten with a wrench.
(3) Unscrew the head cap of the coarse and fine connection pipe of the air source heat pump host high-pressure valve and low-pressure valve, screw the other end of the coarse and fine connection pipe to the inlet of the water tank and the outlet of the coarse and fine connection pipe, and tighten it with a wrench.
5, Pipe exhaust installation requirements
(1) Remove the cap from the adjustment port of the low-pressure valve and high-pressure valve.
(2) Connect the vacuum pump interface to the fluorine injection port.
(3) Make sure the vacuum degree is qualified and the evacuation time is not less than 20 minutes. If it is inconvenient to evacuate, you can use R22 refrigerant to evacuate outside and check for leaks.
(4) Use the inner six wrenches to turn the spool of the low-pressure valve and high-pressure valve in the counterclockwise direction until they are completely open. Recap all caps and tighten them.
(5) Use soapy water to check the connection of each tube and the mouth of each cap to see if there is any leakage, if there is, it must be tightened with a wrench until it does not leak, no leakage is allowed.
1, Before installing the main unit, you need to survey the installation site and select and determine the installation location of the main unit.
2, Make the foundation of the main air source heat pump unit, if the installation location is determined to be on the ground, cement can be used, and the thickness of the cement is about 15cm to 20cm.
3, Place the main unit of the air source heat pump and adjust the position of the unit to ensure that the main unit is placed smoothly.
4, Connect the water system, mainly the connection of the pump, valve body, filter, and other parts between the main unit and the water tank.
5, Connect the circuit system, mainly the power cord, pump, solenoid valve, water temperature sensor, pressure switch, etc. by the wiring diagram requirements for the connection.
6, The water line test pressure, and test pipeline connection for water leakage.
7, the machine test run, the system of the parameters to check.
8, Pipe insulation, such as the use of rubber insulation material for the water system insulation.
