Ground source heat pump working principle
The difference between the water source heat pump and the air
source is that the low-temperature and low-pressure liquid
refrigerant exchanges heat with the water in the water/ground
source pipeline in the evaporator, absorbs the heat Q1 in the water
and evaporates into a low-temperature and low-pressure gaseous
state, and then enters into a vaporized state. Compressor works
through compressor W, is compressed into high temperature and high
pressure gas, then enters condenser, exchanges heat with indoor
water, transfers heat Q2 to indoor water, and the refrigerant
condenses into high temperature and high pressure liquid, and then
enters the expansion valve. With throttling, the refrigerant
becomes a low-temperature and low-pressure liquid, and the
throttling refrigerant enters the evaporator and undergoes heat
exchange and evaporation, thereby realizing inverse carnot
The whole process, also Q2=Q1+W in this process |
Porduct feature:
1. Economical operation
Generally cost less to operate than other types of conventional
heating systems, save your electricity or gas bills.
2. Safety
Operate at a high efficiency with no flames, fumes, or flues; Water
and electricity isolated
3. Environmental friendly
Transfer heat that’s already in the environment; Low CO2 emissions.
4. Easy operation
With intelligent control systems which convenient and simple
operation
5. Constant hot water supply
Provide hot water no matter in cloudy day, snowy day or at night,
unlike solar collectors which have to be facing the sun.
6. Wide application
7. Heat pump water heater can be applied to sanitary hot water,
house heating .
FAQ
Q1. Can I have a sample order for Heat pump or Water tank?
