Description
Technical field
The utility model relates to a kind of immediately heating water heater, also relates to a kind of water heater that utilizes heat pump to heat.
Background technology
Usually immediately heating water heater be called again fast or, the instantaneous water heater, be characterized in: the cold water superheated water goes out, as long as open flowing water Valve, namely can continuously supply with hot water in the short time, during without hot water, shut flowing water Valve cut-out water route and can stop heating at short notice.Present immediately heating water heater mostly is electrical heating type and combustion type.
The principle of electrical heating type immediately heating water heater is to use more powerful electric heater that the cold water of the heating region of flowing through is carried out Fast Heating, make it the serviceability temperature that reaches predetermined rapidly, reach cold water and advance the purpose that hot water goes out, because it has cancelled the water storage device (for example the volume of the moving water storage device of domestic, electric water heater is generally up to tens of liters) on the heat storage type water heater, therefore its volume is small and exquisite, easy for installation.Again owing to need not the storage water in the water storage device is heated to uniform temperature before its use, water consumption also can not be subjected to storing the restriction of the water yield and temperature, and can plug and play, therefore greatly convenient than the heat storage type water heater, and the characteristic of its plug and play, need not during standby storage of water is carried out heat tracing, saved energy resource consumption greatly, more energy-conserving and environment-protective.
But the electrical heating type instant water heater does not possess mounting condition because its power is bigger under some circuit environment, because electrically heated characteristics, its heat conversion efficiency can not be satisfactory.
The combustion gas instant water heater scope of application is also comparatively extensive, but its employed combustion gas (natural gas, liquefied petroleum gas or water-gas etc.) is non-renewable energy resources, therefore be a kind of waste to valuable natural resources, and there is the anthracemia equivalent risk in gas water heater owing to burning reason such as insufficient.
Air-source water heater claims that again air source hot pump water heater is a kind of heater types of being a dark horse in recent years, its principle is to utilize that the refrigerant in the heat pump absorbs airborne low temperature heat energy come in the water heater, be converted into high temperature heat through after the compressor compresses, thereby water is heated.Because adopt heat pump to shift the mode that heat heats, this water heater has energy-efficient characteristics, have to report that its energy-saving effect is 4 times of electric heater, be 3 times of gas heater.
The air energy heat pump heat supply heating system that existing air-source water heater adopts generally is made up of three parts, and the one, host machine part, the 2nd, water tank part, the 3rd, heating system part; For the domestic type water tank, 1, capacity is generally at 150-320L, water tank is bulky, need occupy construction area greatly during installation, even the water tank that has uses support to be installed on outside the wall, because water tank itself adds the weight of water, this type of mounting means is quite dangerous; 2, the material and the technology that adopt of inner water tank itself, no matter be stainless steel inner container or enamel inner container, because the defective of manufacturing process, radiator leak is difficult to avoid; 3, the heat exchanger of water tank inside generally adopts copper pipe or stainless steel tube, and in the relatively poor area of water quality, heat exchanger tube can be corroded and bore a hole, and causes coolant leakage, in case leak, will be fatefulue for unit; 4, need tube connector to link to each other between main frame and the water tank, the artificial coolant leakage phenomenon that produces when being difficult to avoid installing like this; 5, because the characteristic of storage-type heat pump need water temperature is risen to higher temperature, and required time is longer, can not satisfy instant water requirement, and to the water later stage, fluctuating temperature is bigger the comfortableness that influence is used; In addition, the height of condensation temperature determines the energy consumption of unit, and the unit of tradition band water tank moves under high condensation temperature and high condensing pressure for a long time, to life-span of compressor will be a very big test; 6, adopting the water tank of storage-type, generally all need during water to mix water, several problems, 1 can occur like this) the hot water utilization rate of water tank the inside is not high; 2) water tank is in insulating process, and descending inevitably appears in water temperature, increases energy consumption; When 3) user's house ornamentation is used water valve, must need to install mixed water valve, increase material cost.When 7, general heating system is taked heat in the water tank, all need a heat exchange coil be installed in that water tank is inner, constitute the closed-loop path with floor heating coil pipe or radiator and water circulating pump, increase the difficulty of water tank production technology like this, also occupy water tank capacity.
Therefore at present the principle defective that has it to be difficult to overcome of various water heater solutions in the industry.
