How to reduce heat pump noise?

The normal highest noise for heat pump is 50 to 60dB(A), but some intel-brand can make that to 43dB(A), Generally it is acceptable within 60dB(A), which is similar to indoor talking.

So we can reduce noice from two aspects:
1, Compressor shake: Normal compressor will rub with floor, or will impact with tubes and cases.
2, Fans: As the unscientific installation of the heat pump, it will case shrill voice.

We suggest below items:
1, Floor installation: If floor, better use some rubber to release shake and keep horizontal.
2, Balcony installation: we suggest a 45 degree diagonal bracing, to depart the press from vertical and horizontal.
3, Indoor window installation: Most time, heat pump is mounted beside the indoor window, we suggest keeping heat pump flown direction is perpendicular to wall, and parallel to indoor wall, by this installation, it can release the noise from wind flow.

Let Wotech tell you how to distinguish the heat pump quality.

The air source heat pumps have the differences between the good quality and poor quality, but this differences is difficult for consumers to find out and adjusting when they choose the heat pump. Today, Wotech will list several tips for you to help you with the heat pump selection.

1. Check the compressor whether is the famous brand, such as Panasonic, Copeland. Because these high quality compressor could protect themselves from being broken by the high temperature and high current effectively. Compare to other brand, the failure rate is more lower.

2. Whether the COP is high? Whether the inner structure is close? It should ensure there is no gas leakage, at the same time, it has to ensure the unit clean, which can extend the using and maintain period.

3. All the temperature sensor should be connected in right way, the controller should send command feedback to the working part cerrectly, which decided the heat

pump whether could work efficiently.

4.The heat pump should adjust the system situation by itself according to the working temperature and heating capacity,

5.You should check the water pressure whether is stable, and whether could matching the running water system well to finish the whole circulation process,which ensure the system will not be threatened by the high temperature.which could realize the intelligent defrosting and ensure the system could work safely.

How heat pump works?

1. The EVAPORATOR collects heat from  the outside ambient air, pre-heated by thesun. Heat pumps high volumes of outside air are drawn into the unit by the fan and expelled through the evaporator fins. The evaporator has liquid refrigerant passing through it, which is at a considerably lower temperature than the ambient air, therefore the air gives its heat to the refrigerant, which then vaporizes. This is pre-heating.

2. The COMPRESSOR where it is compresses and upgraded to a much higher temperature. The hot vapour now enters to the CONDENSER.

3. The CONDENSER where it is surrounded by water from the heating system. The heat is given off to the cooler water and the now cooler refrigerant returns to its former liquid state but still under high pressure from the compressor. This pressure isreleased by passing the liquid through the EXPANSION DEVICE.

4. The EXPANSION DEVICE and from there now at low pressure, it is returned to the evaporator and the cycle starts again.

How to choose a good heat pump?

1.Compressor. The compressor is the core component of the air source heat pump. The compressor with poor quality will effect the heat pump lifetime directly.So, when you are selecting the heat pump, you should notice the compressor. All the wotech heat pumps are adopted the imported brand compressor(Panasonic compressor for domestic heat pump, Copeland for commercial heat pump.)

2.Water tank. The water tank decides the safe, keep warm performance and the lifetime of the heat pump.So when you are selecting the heat pump, you should notice the inner material and quality.  

3. Thermal insulation. Heat pump is a storage water heater. When the water temperature reach the set point, it will stop heating, when it lower the set point,it will start heating again. So if the thermal insulation of the water tank is poor, it will cost a lot of energy. Wotech heat pumps are adopted the 500mm thickness polyurethane foam layer, which is with the advanced high pressure foaming technology to once moding. Every 24 hours just decline 4℃, which is more energy saving.

4.Evaporator.The evaporator quality is related to the heat pump efficiency. The evaporator tempereture is required to be lower than the air temperature,then it could absorbing the heat from the air.So the evaporator will easily has the condensate water. If the condensate water on the fins could not drain then it will easily attched the dust and become the dirt. In winter it will frozen and effect the heat exchange. Wotech heat pumps are adopted the hydrophilic concave-convex fins,which make the evaporator absorbing heat more quickly and higher efficiency.

	Solar power feature	Wotech air source heat pump feature
Energy saving	Use for free when the sunlight is strong. Assit heating when it rains or the sunlight temperature is low. Use electricity to heat at least 120 days all the year round, amounting to 500 days power consumption madeby air power heat pump set.	Average efficiency is 460%. The operation fee is low for a year, just amounting to 65% of solar power system.
Safety	Electricity is set in water. It has the danger of leakage, drying out etc.	Separate water and electricity prevent leakage, etc.
Steady	Scaling happens easily in high temperature within vacuum heat collector. It lowers heat exchange efficiency. After two years, the heat exchanger efficiency is obviously lowered, and the supply water is unsteady.	With patent design,the set operates steadily rapidly exchange heat dynamically. Scale formation rate is low. Supply water for a long time is steady. Water supply is steadyfor long.
Scope of application	The floor space occupied is large(1㎡ absorbing board produces water about 60L/water day) Restriced by site. Absorbing effectefficiency impacts a lot by temperature.	The floor space occupied is small. Quickly adapt to all kinds of site setup demand: below-10℃-40℃ environment, it can operate efficiently.
Flexibility	Single regular mode design	According to users practical need, it designs flexibly, managing the system openly, regulating operation ratio freely.

How to make heat pump work with good effect in winter?

The domestic heat pump will have a problem that could not supply enough hot water in winter.The following are some notice for using domestic heat pump in winter. 

1. Adjusting temperature. In spring, summer and autumn, the water capacity produced by heat pump is rich, so the the running temperature could be adjusted to low, about 45 degree is available. In winter, if you don't adjust to high temperature, the speed of water production will lower than the water consumption, so the temperature should be adjusted to 55 degree.

2. Water consumption. Because the low temperature in winter, the water capacity production is low, if you don't have an enough large water tank, you should not use the water in the same time. The family shower time could be staggered.

3. The water return device. Do not set the water return device in auto mode. Because the low temperature in winter, the water in the pipe would be cold easily, which cause the water return and the water temperature in the tank will loss. So in winter, the water return device should be set in manual mode or water flow mode or remote control mode.

How to make a good installation of a air source heat pump?

In recent years,with the traditional water heater accident continue to increasing,the fourth generation safe air source heat pump is more and more popular with users.But as a new product, many users do not know how to install the unit, if the heat pump is intalled in a improper way, the energy saving effect would be not obvious. Below is some installed suggestion from Wotech heat pump.

1.Install location select. The heat pump could be installed in the balcony, terrace, outer wall, roof, ground and some ventilation places. The water tank could be put in the kitchen, restroom, and the main unit could be installed on the outer wall which near the water tank. The standard copper connect with main unit and water tank is 3 meter, too long is not good for refrigerant cycle, while the vertical tank needs a larger ground area to be placed.

2.The installation needs the drain device. There is some condensate water during the heat pump operating, so the location should be have the floor drain,gutterway and some drain device.

3.The heat pump controller position: The controller needs near the device, could be prevent by the rain. As the function would be set in advanced on the controller, so it is no need to install in a conspicuous position, the wall of balcony and corridor are both available to install.

4. Heat pump performing test procedure:1.connect the cold water pipe first, the cold water pipe was connected with a safe valve;2.Filling water into the water tank till there is water flow out the hot water mouth(that means the water tank once full of water),then turn off the valve,stop water filling.That is an important step(the water filling should be finished before the hot water pipe connection).
