The influence of the total heat capacity of beauty on hot water system

The total heat capacity of water heater system has a great influence for system operation characteristics. Figure 2 is based on the example of calculation results of drawn up. In a water heater system, can be effective use of the heat capacity of water known as the effective heat capacity. Such as concentrated in hot water solution at the bottom of the tank, the water in the tank heat capacity is the effective heat capacity, and thermal collectors, increase tube, decrease the water in the pipe is not included within the effective heat capacity. In addition to the effective heat capacity, the rest of the total heat capacity as invalid heat capacity. If the water in the tank to value as the abscissa, with an average temperature of water in the tank daily peak as the ordinate, put the calculation results, we found that in this example, logarithmic and water temperature linearly law of water tank, water decreases, and the water temperature to rise. In terms of the absolute value of water temperature rise, in Novosibirsk more apparent than in cold season, the closer it gets to the best Angle at the same time, the appreciation.

Can extend the sun water heater in the year of the important economic significance in use. If when designing water heater that water tank capacity is small enough, then you can see, from the group even in the cold in January, the average temperature of water tank is about 40 ℃ to 37 -, close to the temperature of the bath water.

Under the condition of reduced effective heat capacity is small, the proportion of invalid heat capacity is greatly improved, because the latter in the effective heat capacity (such as the water in the tank capacity) reduced the basic remain unchanged. Water heater running characteristic depends on the total heat capacity system, the total heat capacity of a certain condition, the invalid heat capacity not drop down, effective heat capacity also can not go up. So. When designing water heater system, especially the small water tank, should strive to reduce the invalid heat capacity, for a larger role in the heat capacity of components should be serious consideration. In addition, in the small tank scheme in order to reduce the proportion of invalid heat capacity, might as well take the hot water from bottom of the minimum system, makes the area.the, connecting the water in the tube can be effectively used.
