My unit is in Tianjin, the new staff dormitory has 100 bathrooms, a total of 400 people live, please expert advice: use solar water heater good? Or air source heat pump water heater okay? Or the other way? Please explain the cost, advantages and disadvantages. Thank you
First, how to understand "heat pump"?A simple example of the car consumption a few liters of gasoline can put several tons of goods from one place to another, heat pump can absorb heat from the nature of the "handling" by heat pump (electric power driven heat pump), was used for energy production and life.Two, heat pumps have several?According to the heat source, the heat pump can be divided into air source heat pump, water source heat pump and ground source heat pump.Three, is the heat pump water heater solar products?Broadly speaking, but the heat pump and conventional solar products are essentially different, mainly reflected in the different working principle: conventional solar products must rely on exposure to direct sunlight or heat radiation system to achieve the effect, and the heat pump unit is mainly to absorb heat environment to achieve the heating effect.
400 per person 40-50L of water consumption, 400 x 40=16000L=16 tons, insulation water tank to 15 tons, -20 tons between.
Recommend the use of air source heat pump + solar hot water project, so the operation cost of the province, only to add solar electric auxiliary heating, and electric heating is very large heater, power consumption greatly.
