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.

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.

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.

Is it good for using heat pump and solar heater together?

Solar as a renewable energy, could heat water without electricity under the rich sunshine, which is high energy-saving.But without the sunshine and in the rainy day,the solar will expose its disadvantage. While heat pump will not be limited by the wheather eventhough it consumes a little bit electricity. No matter in cloudy,rainy day, as long as there is air, there is water. It is no doubt that heat pump is the best fourth generation water heater.

Solar and heat pump both has their own features, if they can combine together that would effect the best advantage. For example, under the sunshine, the solar heater could be used for absorbing the heat and supplying hot water. Under the rainy day, the heat pump could be used as the main heater to absorbing the heat from the air. The two heater as the supplement of each other, not only could offer the hot water in 24 hours but also save energy and eco-friendly.

So how is the reality application? For this problem, Wotech has made a lot of successful project with solar and heat pump combination, which are widely applied in the hotel, school, hospital etc.and get an outstanding energy-saving effect. For example, in YunNan province, there is a project adopted a combination of 50 solar tubes and 4 heat pumps, which could offer 50 tons water everyday.For more welcome to visit us on www.ecowotech.com
