With the enhancement of people's awareness of environmental protection and scientific and technological progress, people are now more and more in pursuit of energy-saving and environmentally friendly equipment, and the screw water source heat pump such an environmental protection equipment can be both cooling and heating by many consumers love, that in order to let you understand more about our screw water source heat pump, today we will introduce to you! Screw type water source heat pump unit service life how long.
The water source heat pump unit runs stably, almost unaffected by the weather and the environment, temperature changes, even in the cold winter heat production will not decay, and no frost defrosting concerns. In addition, the water source heat pump unit has fewer parts, simple maintenance, the host operating life of up to 15 years or more.
Second, the water source heat pump unit maintenance needs to be carried out what are the steps of the work
In the modern production and life of the water source heat pump technology is more and more widely used, according to the use of the different forms of low-level heat source, can be divided into the ground source heat pump soil source heat pumps and water source heat pumps, water source heat pumps according to the source of water is different, and can be further divided into the surface water water source heat pumps and groundwater water source heat pumps. Water source heat pumps are divided into soil source heat pumps and water source heat pumps. Water source heat pump maintenance is conducive to the prolongation of the life of the equipment, so be sure to do a good job in strict accordance with the specifications of the maintenance of equipment.
1, winter set of anti-freeze, ensure that the host without power, if the pump and air conditioning host chain control, the host will automatically implement the system anti-freeze protection function; if not chain control, if not for a long time without air conditioning, you need to ensure that the water system and the set of heat exchanger within the water discharged clean. Heat pump unit used in winter to ensure that the host, pump, the main power supply shall not be turned off. It is best to take the pump and the host interlocking control to ensure that the unit performs the function of frost protection, at this time the pump is required to start automatically, can not realize the interlocking control according to the temperature every 1-5 hours to open the pumps for 5-10 minutes, if necessary, open the main body of the hot run.
2, the set has been adjusted by the manufacturer to the best working condition, the user should not arbitrarily change the operating parameters have been set, the set is strictly prohibited frequent operation of the switch, the number of times the power on shall not be more than 6 times/hour, and the power on running time should be more than 5 minutes. The main circuit power switch must be kept on during normal use to maintain the normal operation of the compressor oil heater.
3, equipment operation period, should be carried out once a month, the whole machine inspection, unit noise and other checks and system piping reinforcement, compressor and auxiliary components inspection and maintenance, check and record the voltage and phase-to-phase voltage, megohmmeter measurement and record the motor winding resistance resistance value, check the refrigerant system sealing, check the compressor unloading device, according to the actual operation of whether to replace the filter drier, the unit runs Replace the filter drier after 4000 hours of operation. Check all other lubricating oil system components, check the expansion valve adjustment. Check the four-way valve, solenoid valve work.
