Description
Technical field
The utility model relates to the electric heater technical field.
Background technology
Electric heater is a present family water heater commonly used, and standing electric heater has storage-type electric water heater, instant electric water heater and preparatory instant electric water heater.
Storage-type electric water heater be preheating electric heating tube through lower-wattage with the preparatory water storage heating in the water storage casing, the power of its electric heating tube generally is not more than 2.5kW, is suitable for family and installs and uses.Its shortcoming is that volume is bigger, needs in the time of using hot water in advance the preparatory water storage in the water storage casing to be heated, and heat time heating time is longer; As to make electric heater have hot water to use at any time; Then to keep electrothermal tube energising with water heater; Just the preparatory water storage in the water storage casing is remained on certain temperature (60-80 ℃) at ordinary times; Though this way has the effect of plug and play, keep also need providing electric energy (because heat radiation of casing), waste electric energy with one case hot water.
The instant electric water heater does not then have the water storage casing; Have only the very little heated shell of a volumes, electrothermal tube is installed in the heated shell, makes running water executed out hot water through heated shell by the electrothermal tube heating; It has the little advantage with instant-heating of volume; But more than 6kW, to having relatively high expectations of circuit environment, general domestic consumer is not suitable for installing and using the electrothermal tube power that reaches this effect at least.
The instant electric water heater then is storage-type electric water heater and instant electric water heater's combination in advance, at the water side or the delivery port of storage-type electric water heater the connection instant electric water heater is installed.Its principle is that the preheating water that heats the water storage casing with the instant electric water heater is to execute out hot water; So just, can make instant electric water heater's power need not be too big (less than 5kW); Less with the volume of the water storage casing of storage-type electric water heater; Advantage with plug and play is suitable for average family and installs and uses.
In recent years be a kind of energy-conservation electric heater---heat pump water heater to occur; It utilizes the equipment like air conditioner according to contrary Carnot's principle, and critical piece includes compressor, condenser, choke valve and evaporimeter; Make working medium through compressing → thermodynamic cycle process of condensation → throttling → evaporation; In condensation process, condenser is emitted energy to environment, and these energy are carried out heat exchange and obtain hot water cold water with heat exchanger or water storage casing.According to measuring and calculating, the power consumption of this water heater is 1/4 of an electrical heating tubular type water heater.
Fluorine Lyons 22 (code name R22) is as cold-producing medium owing to be widely used in the present refrigeration system, and evaporation rate was very slow when this cold-producing medium was lower than subzero 5 ℃ in environment temperature, and effect is relatively poor, has influence on the heats of water heater.Therefore; Most of Teat pump boilers will install electric heater additional and carry out assistant heating; Be 200920313464.2 patent like application number---have the high-efficiency heat pump hot-water device of auxiliary electric heater unit; When ambient air temperature is low, open electric auxiliary heating device water-cooled heat exchanger is carried out the secondary heating, make water temperature can reach customer requirements.
