Heat pump---The third generation of heating

In the first generation of heating, what we pursuing is just being offered heat no matter by what methods in the cold season. In the second generation, we more focus on the efficiency, except the heat we needed in the winter, we also pay more attention on the energy use. In the third generation, we put forward a higher requirements for heating, not only require for heating, but also the health and environment. So the air source heat pump has been the popular choice in the new heating generation, which plays an important role on the heating development.

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.

Wotech heat pump compares with Solar heating.

	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.

Heat pump performing test

Wotech's development is base on the effort of quality, which is strictly quality control from the spare parts to finished products, Besides, the heat pumps would be made a simulate performance working.

How heat pump works?

1. Cryogen temperature drops to -20℃ after the pressure releases. When ultra-low temperature liquor cryogen enters and flows in absorbing heat evaporator, it meets air about 20℃. Through air heat transfer (the temperature different is 40℃), ultra low cryogen absorbs air heat, its temperature rises to 20℃.

2. Cryogen of 20 enters low temperature compressor, gets pressed, heated up, and turns into high pressure 80℃ air. Discharged from compressor, and then enters heat exchanger.

3.Vaporized cryogen temperature of 80℃ passed heat to low cold water in heat exchanger, changing into 60℃ life used heat water which is pumped into warm keeping tank for storage through circulating pump. High temperature cryogen heat releases and turns into high pressure liquor.

4.High pressure liquor cryogen throttles and lowers pressure through expansion valve, making entering into evaporator to absorb.

5.According to Reserve Carnot Circle Theory, compressor constantly repeatedly circles. The whole course is to transfer heat. As long as it use a kilowatt-hour electricity to drive compressor to work, it can absorb heat in the air equat to that produced by 3-6kh electricity, passing to water. Obviously it save's energy and work safely.
