There are three functions of air source heat pumps that are widely used in home and commercial spaces - hot water, heating and cooling. Air source heat pump trigeneration is to use a set of air source heat pumps to provide three functions such as hot water, heating and cooling at the same time. Basically, using a set of air source heat pump trigeneration can replace a variety of products such as water heaters, air conditioners, and floor heating. This is also a relatively ideal optimization collection system.
Some people have done trigeneration before, that is, with domestic hot water, but because the heat demand for domestic hot water is huge, during the process of making hot water, generally refrigeration and heating are stopped, which will cause temperature fluctuations and people will feel uncomfortable. Another point is the complexity of the system. The more complex the system, the more likely it is to have problems, and there are more after-sales problems. After several years of actual market testing, except for a few air source heat pump manufacturers, others are promoting air source heat pump dual-generation, air source heat pump dual-generation, which can be said to be quite mature at present.
1. Improved comfort
When the water system central air conditioner is cooling in summer, the terminal water exchanges heat with the air, and the wind blown out is relatively soft. Relatively speaking, the moisture content is higher than that of the fluorine machine refrigerant system, so there will be no dry mouth and tongue feeling in the room after long-term cooling, and the comfort level is higher. The core components of the air source heat pump dual-generation system have introduced full DC inverter technology, which is quieter in operation.
2. Low-temperature heating
With the rising demand for "coal to electricity", air source heat pump technology has been continuously upgraded, and the low-temperature heating performance has been greatly improved. Some low-temperature units can achieve stable heating at -20℃ to meet the stable heating needs of cold areas in the north.
3. Efficient defrosting
The buffer water tank in the heat pump system plays an important role, including enhancing stability, storage, buffering, automatic exhaust, protection, cleaning and other functions, making the temperature change of the system more stable, avoiding frequent start and stop of the unit when the host is running at low load, ensuring the smooth flow of water in the system, and ensuring that there is a certain temperature in the water tank during the defrosting process, which can shorten the defrosting time, reduce heat consumption, and avoid fluctuations in indoor temperature caused by host defrosting, resulting in a decrease in comfort.
4. Capacity adjustment
The pressure differential bypass valve plays a big role in the heat pump system. When part of the load is applied, the electric valve at the end is automatically closed, the pipe network resistance of the system increases, the pressure differential of the main water supply and return pipe increases, the pressure differential of the manifold increases, the pressure differential of the pressure differential bypass valve opens, and part of the flow flows through the bypass valve to ensure the flow demand of the chiller. It is used to control the basic flow of the water system to ensure the reliable operation of the system, increase the service life of the host, and greatly reduce the occurrence of system operation failures.
5. Intelligent control
Through the applet management, the heat pump operation mode can be adjusted at any time, the energy consumption of the heat pump can be detected, the sensors in the home can be linked, and energy management can be realized for multiple intelligent heat pumps; the intelligent control module set in the system can monitor the operation of the heat pump, and if any abnormality occurs or there is a deviation from the normal range, an early warning operation will be carried out.
