Three Ways of Air Source Heat Pump Heating

As one of the latest heating methods, air to water heating system  has not only played a significant role in the transformation of coal to electricity in the north, but has also been favored in the increasing heating demand in the south.
 
Although air source heat pump heating has the advantages of low cost, energy saving, rich functionality, high comfort, and a wide range of low-temperature operation, it is possible that if the choice of air heating and end-fitting methods is not appropriate in different regions and different heating locations, there is a possibility that The advantages of air heating will be greatly reduced, and even the saying that "air source heat pump is not energy-efficient" will appear.
Three Ways of Air Source Heat Pump Heating
1. Air Source heat pump host + fan coil heating system
Advantages: The fan coil is usually concealed ceiling, will not occupy the living space, save space compared to the surface mounted heat sink, and the outlet is gentle, not as dry and uncomfortable as the hot air from the air conditioner or electric heater, and the wind disk heat exchanger With high efficiency, the heating area will reach the set temperature in a short time.
And because the outlet water temperature is around 45°C, the efficiency of the air heat pump is high. If a heating/cooling air source heat pump unit is used, it can also replace central air conditioning to achieve summer cooling.
Disadvantages: The vast majority of fan coils are hot air blowing on the head, easy to form a dry head and cold feet phenomenon, comfort is generally. There are also a small number of new wind-bottom floor heating machines at the bottom.
Allowing the warm air to blow out from the bottom is more effective than the hot air at the top, but at the same time there are problems such as taking up the living space and causing surface dust to be carried into the air.
Applicable occasions: Suitable for users with discontinuous and intermittent heating needs. For example: Shangchao, hotels, offices, weekends and other family.

2. Air source heat pump host + floor heating system
Advantages: Recognized as the most comfortable home heating method, uniform heating temperature, warm heat from the feet, in line with the Chinese theory of "cool head and warm feet". The temperature of hot water required for floor heating is generally around 40°C, and the efficiency of air can be higher when the temperature of hot water pumped out is about 40°C.
Disadvantages: The pre-installation of floor heating is more complicated. If the renovated home has been renovated, the floor has to be opened for installation and the initial installation cost is higher. In addition, when the air can warm up, it needs to be warmed up in advance and heated slowly.
Applicable occasions: Suitable for places requiring continuous heating, and users with higher requirements for heating comfort. For example: hotels, villas and homes for the elderly and children.
3. Air source heat pump host + radiator heating system
The required hot water temperature for the radiator is generally required to be above 55°C. The higher the hot water temperature, the lower the efficiency of the air heat pump, because the winter temperature is already low, which makes the heat pump more difficult to obtain heat in the air, heat pump The energy efficiency will be greatly reduced, the energy consumption of the equipment will increase substantially, and energy-saving heating will not be achieved.
Advantages: Radiator is instant heat, faster heating; can be installed, not affected by the floor.
Disadvantages: slow heating, non-uniform heat, high temperature requirements for hot water, large air load heat pump host, low heating efficiency, low energy consumption in areas with low ambient temperature and high heating load.
Applicable occasions: Suitable for users with low heating load, good indoor and outdoor thermal insulation effects, and users who cannot install floor heating or wind tray after renovation or renovation of an existing one.
The above three methods are based on the actual needs of users and the use of the environment to determine, and sometimes can also be combined in a variety of ways to heat, such as in the bedroom floor heating, living room mounted wind tray.
In addition, the air energy heating system also needs to be equipped with a suitable buffer thermal insulation tank, so as to utilize the temperature difference between the white worms and the valley price to achieve better energy saving and heating effects, and extend the service life of the air energy heat pump host.
Generally speaking, through the professional company's rational allocation of air energy heating methods plus standard installations and other complete system construction, the air energy can be finally heated to achieve energy-saving and environmental protection, intelligent heating, save money and save money.
