1, Daikin single cooling central air conditioning and Daikin heating and cooling central air conditioning: Daikin single cooling central air conditioning can only provide refrigeration function, and is suitable for use in places where refrigeration is only needed. Daikin heating and cooling central air conditioning can provide cooling and heating functions, which is suitable for use in areas with large temperature difference between the four seasons.
2. Daikin fixed frequency central air conditioning and Daikin variable frequency central air conditioning: Daikin fixed frequency central air conditioning has stable cooling and heating effect, but high energy consumption. Daikin variable frequency central air conditioner can automatically adjust the cooling and heating effect according to the change of indoor temperature, and the energy consumption is relatively low.
3. Daikin floor heating central air conditioning and Daikin air duct central air conditioning: Daikin floor heating central air conditioning can evenly distribute heat energy throughout the room and is suitable for use in cold areas. Daikin air duct central air conditioning can transport cold and warm air to all rooms evenly through the air duct, which is suitable for places that need zoning control.
How to choose central air conditioning;
1. area and demand: determine the area to be covered and the number of rooms, which will determine the required cooling/heating capacity. Generally speaking, the required cooling capacity per square meter is between 150~200W, but the specific demand should be comprehensively considered according to regional climate, indoor equipment and other factors.
2. Energy efficiency grade: Pay attention to the energy efficiency grade of central air conditioning and choose products with high energy efficiency. Energy efficiency grade is usually expressed by energy efficiency ratio (EER or COP). The higher the value, the better the energy efficiency, which can save energy expenditure.
3. Refrigerant types: At present, common refrigerants are R4 10A, R22, etc. It is suggested to choose environmentally friendly refrigerants, such as R4 10A, because R22 is being eliminated.
4. Brand and quality: choose well-known brands and manufacturers with good reputation and good after-sales service. You can consult other users' experiences and refer to consumer comments.
5. Filtering and cleaning function: Check whether the central air conditioner is equipped with filtering and cleaning function, which can effectively remove dust, bacteria, viruses and other harmful substances in the air and provide a healthier indoor environment.
6. Noise level: Understand the noise level of central air conditioning, and try to choose products with lower noise to avoid disturbing the living comfort.
7. Control mode: consider the control mode of central air conditioning, such as remote control and mobile APP control, which is convenient for daily use and management.
8. Installation conditions: understand the installation requirements and conditions of central air conditioning, including the placement of outdoor units and pipeline layout.
