Performance of CO2 Heat Pump Water Heater with Inverter Technology Hot Water Solutions
The CO2 heat pump uses heat from the air to heat the house or provide hot water. Carbon dioxide (R-744) is a very environmentally friendly refrigerant that can effectively help reduce greenhouse gas emissions.
The heat pump is an efficient and environmentally friendly heating system. 1kW of energy input can be converted to 3.9kW of heat output. Compared with heating systems that use electricity or natural gas, it can save 75% of the cost.
The CO2 heat pump has a higher level of safety, because carbon dioxide (R-744) does not burn to reduce the risk of fire. And, it will not harm the environment.
The unique ability of the R744 heat pump to generate 90°C hot water makes it suitable for various industrial, commercial and residential projects, including food processing plants, dairy products, shopping centers, apartments, hotels, restaurants, hospitals, elderly care, entertainment and education facilities .
The working principle of CO2 Heat Pump:
The R744 heat pump hot water system absorbs energy from the ambient atmosphere and converts it into heat. The ozone-friendly refrigerant (CO2) absorbs heat and then flows into the compressor where it is converted into high-temperature gas. Then it passes through the condenser in the water heat exchanger. The water is heated and then stored in the hot water tank for later use.
CO2 Heat Pump Features:
1. Power range: 14kW, 27kW, 41kW, 49kW, 95kW, etc.
2. The world-renowned scroll compressor is highly efficient and stable.
3. CO2 R-744 refrigerant, environmentally friendly, does not destroy ozone
4. Working environment range: -20ºC~43ºC
5. Intelligent controller and fast adjustment microprocessor can be adjusted.
6. PVC titanium alloy heat exchanger has sufficient corrosion resistance and more durable.
7. It has protection functions such as overheat protection, high pressure protection, high temperature protection, and low pressure protection.
8. Copper pipes with grooves inside can improve efficiency.
9. Four-way valve ensures reliable defrosting function
10. The initial investment is relatively low, easy to install and maintain
