Description
Technical Field
The utility model relates to a water heater especially relates to a shower is with instant-heating type heat pump water heater and.
Background
In modern daily household life, a water heater for shower has become a necessary product for most urban residents. The existing household water heater mainly comprises: 1 gas water heater, 2 air can the water heater, 3 electric direct heating water heater, 4, solar water heater, 5 water source heat pump water heater.
The gas water heater is characterized in that a special metal water pipe is coiled in a combustion chamber in multiple layers, natural gas or liquefied gas is combusted under the special metal water pipe under the combustion chamber under the. The water supply capacity of the gas water heater used in the family at present is as follows: the water inlet temperature is 10 ℃, and the water outlet temperature is 40 ℃, and the water inlet temperature is 8 liters/minute, 10 liters/minute, 12 liters/minute, 16 liters/minute, 18 liters/minute, and 24 liters/minute.
2, the air energy water heater is characterized in that outdoor air is blown through a copper pipe (called an evaporator) with a plurality of layers of metal sheets by a fan, liquid refrigerants with the temperature lower than that of the air by 10-20 degrees are filled in the copper pipe, and the liquid refrigerants absorb air heat transmitted through the pipe wall and are vaporized into steam; the low-temperature low-pressure steam enters a compressor, is compressed into high-temperature high-pressure steam, then enters a condenser, exchanges heat with cold water flowing in a copper pipe, and the cold water is heated into hot water and enters a heat-preservation water tank for storage. The steam is condensed into liquid, the high-pressure liquid is decompressed into low-temperature low-pressure liquid (part of the low-temperature low-pressure liquid is directly flashed into steam) through the throttle valve and returns to the evaporator, and the water heater enables the refrigerant to circulate back and forth to prepare hot water.
3, the electric water heater also has a heat preservation water tank, a resistance wire (called as an electric heating tube) with an insulation sleeve is coiled in the water tank, when heating water, the water tank is filled with cold water to soak the electric heating tube, the electric heating tube is powered on, and current flows through the electric heating tube to generate heat, so that the whole water tank is heated slowly to form hot water with a certain temperature, and then is stored for standby after heat preservation.
4, the solar water heater utilizes the curved glass plate to focus sunlight scattered and irradiated on the plate into a plurality of narrow straight strips, improves the energy density, thereby heating water in the lower glass tube to more than 40 ℃, and pumping the water into a water storage tank for heat preservation and storage.

The water making capacity of the water heater using the pipeline natural gas as the gas source can reach 24 liters/minute, and a common household adopts a water heater of 12 liters or 16 liters, so that the water heater is comfortable to wash and the gas cost is low. However, for safety reasons, two gas water heaters are mostly installed in a kitchen far away from a bathroom, a hot water pipeline is long, heat loss is large, the temperature from the outlet of the water heater to a spray opening is reduced by 3-5 degrees, and cold water needs to be discharged for a period of time at the beginning. On the other hand, as for the national overall economic and environmental benefits, the gas water heater consumes more gas, the energy efficiency is low, and a large amount of carbon dioxide greenhouse gas is emitted in the combustion process.

3, the electric water heater is simple to manufacture and low in cost, but the water production capacity and the energy efficiency are lower than those of an air energy water heater, a heat preservation water tank is also needed, the bathing time is greatly limited, and more seriously, the electric heating tube of 220V is in direct contact with water, so that the danger of electric leakage exists. The electric water heater is smelled when people die.
4, although the solar water heater is energy-saving and has large water volume, the solar water heater is greatly influenced by weather, is installed in rainy days without hot water, needs large floor area and is only suitable for households of low-rise buildings. For households in high-rise buildings, although proposals are made for installing the solar panels on the outer wall, the solar panels fall off the ground, so that casualties are caused, and the appearance of the city is damaged.
5, the underground water source heat pump water heater needs to extract underground water, can be used only in families with single houses, and can obviously not be used by ordinary urban residents.
