What is a heat pump water heater? What advantages does it have with an ordinary water heater?
(two) electric water heater;1, the current domestic electric water heater is mainly water storage water heater. Divided into closed and open type of two. The water storage electric water heater is clean and sanitary, and does not need to be installed in a compartment, and no harmful gas can be produced, and the temperature can be conveniently adjusted. The inner chamber of the open water heater is not pressure resistant and can not supply multiple water at the same time; the inner of the enclosed electric water heater is able to withstand pressure and can supply multiple water supplies at the same time.2, advantages: can adapt to any weather changes, ordinary families can be directly installed and used, long time electricity can be large flow of heating water. At present, most electric water heaters sold on the market have anti electric shock devices.3. Disadvantages: bulky, large indoor space, easy to scale, waste of electricity. The new type of electric water heater is equipped with an anode magnesium rod descaling device, which solves the problem of easy scaling. But the anode magnesium bar has to be replaced two years, which brings trouble to maintenance.
(2) flue type water heater: the exhaust gas pipe is installed on the base of the straight row type. The oxygen needed for combustion is taken from the room, and the smoke generated by burning is discharged to the outside through the flue. When installing the water heater, the flue must be installed. When using, pay attention to the smooth exhaust of the flue and prevent the flow from flowing backward. Strong emission type water heater based on flue type adds an exhaust motor through the flue to discharge the waste gas, running, flue gas is forced to discharge through the smoke, but the oxygen needed for combustion is still from the interior.(3) balance type water heater is realized: three before a great leap forward, the shell is sealed, the flue and shell into one made of two layers of inner and outer flue, from the wall to the outside to the water heater operation when the oxygen from the outside through the outer layer of the air flue gas supply, combustion generated from the inner flue is discharged to the outside, so it is not on the indoor air consumption, no pollution. But installing such a heater needs to be as reserved as an air conditioner.
It is compressed into a high temperature (higher than a high temperature water) high pressure gas, so that the heat is released from the heat to the high temperature, and the heat is transported from the low temperature heat source to the high temperature heat source. Heat pump is divided into air source heat pump and water source heat pump.Compared with the ordinary water heater, the heat pump water heater is relative to the energy saving.
Heat pump water heater is the use of "reverse Kano" principle, through the medium, the heat from the cryogenic object to the high temperature of water equipment. The heat pump device can make the medium (refrigerant) phase change and become lower than the low temperature heat source, so as to absorb the heat of the low temperature heat source spontaneously, and return to the medium after the compressor,
