Air energy heat pump is to use the heat in the air to generate heat energy, can 24 hours a day, high water pressure, constant temperature to provide the whole family with different hot water, heating and cooling needs, and at the same time to consume the least energy to complete the above requirements.
The principle
Air energy heat pumps operate on the "reverse Carnot" principle, the reverse Carnot cycle principle. Operating through a compressor system, it absorbs heat from the air to produce hot water. The specific process is: the compressor compresses the refrigerant, the temperature rises after compression, and the refrigerant passes through the condenser in the tank to produce hot water. The refrigerant after heat exchange returns to the compressor for the next cycle. In this process, the air heat is absorbed into the refrigerant through the evaporator, and the refrigerant is introduced into the water to produce hot water. Air heat pump water heater is a new generation of water heater which is heated by compressor air. Metaphorically speaking, the "outdoor machine" compresses the air like a pump, raising the temperature of the air, and then conducts heat to the indoor water storage tank through a liquid that will boil at -17 ° C, and then releases heat to the water.
The heat pump works on the principle of heating, as opposed to air conditioning refrigeration - the national refrigeration standard is 1000 watts, and electric refrigeration is 2800 watts. According to the principle of heat balance, at least 2800 watts of heat is generated at the same time, plus the input of 1000 watts of electricity, the actual heat generated in 3000- 4000 watts, the heat is transported to the insulated water tank, its power consumption is only a quarter of the electric water heater (even if the thermal efficiency is 100%, the input of 1000 electricity is only 1000 watts of heat).
Air-powered water heaters do not require sunlight, so they can be placed at home or outside. Therefore, most of the manufacturers of the machine have a separate machine and a machine, solar water heater storage after the water is used up, it is difficult to immediately produce hot water. If the electric heating takes a long time, and the air heater as long as there is air, the temperature is above zero degrees Celsius, it can operate 24 hours a day under pressure. In this way, once a tank of water is used, another tank of hot water will be produced in an hour or so. At the same time, it can fundamentally eliminate the electric water heater leakage, dry burning and gas water heater when the use of harmful gas and other safety hazards, overcome the solar water heater overcast and rainy days can not be used and installation inconvenience and other shortcomings, with high safety, high energy saving, long life, no gas emissions and many other advantages. Air energy water heaters generally have a life span of 10 to 15 years.
The installation
Air energy heat pump is usually installed in the kitchen balcony, the outlet is linked to the kitchen through the air duct, so that the cold air blown out can directly enter the kitchen, to achieve the effect of refrigeration. When installing, only the cold and hot water mouth and the house reserved cold and hot water link, can be used, the installation is very simple, but the effect is not too good.
advantages
"Safety + save money + comfort + environmental protection + durable ":
1.safety: no gas, will not produce any exhaust gas, more will not appear "gas poisoning "; No electric heating rod heating, there is no danger of electric leakage, care for family health and safety.
2.save money :COP value more than 3, energy efficiency ratio is high, absolute power saving, money saving. Can save 2/3~3/4 of the electricity BILL, OR SAVE 1/2~2/3 OF THE GAS BILL AND solar water heater auxiliary HEATING BILL.
3.comfort: patent technology - flow indirect heating, automatic constant temperature pressure water supply, in the use of hot water will not be sometimes hot and sometimes cold, hot water pressure, good comfort. All-weather, year-round water supply, to make up for the solar hot water system cloudy and rainy, night, no sunlight, cold when no hot water available embarrassment.
4. Environmental protection: the cold air from the air (heat pump) water heater is conducive to reducing the room temperature.
5.durable: selected world famous brand parts, five-fold anti-rust technology, the shell is made of corrosion-resistant, super-thick coated steel plate or stainless steel plate, the equipment performance is stable, the service life of 15 years.
High thermal efficiency
Compared with coal-fired boiler, oil-fired boiler, gas-fired boiler and electric water heater, heat pump water heater is the most efficient water heater.
The efficiency of oil-fired boiler is 65%-75%, the efficiency of electric water heater is 70%-80%, and the efficiency of heat pump is 300%-500%.
Because heat pump water heaters have a high thermal efficiency of 300%-500%, making hot water extremely cheap to prepare, electricity is naturally saved. Other heat pump products also save electricity, but the difference is in cost.
Heating and refrigeration integrated
Air (heat pump) water heater sets water heating, heating, dehumidification, cooling, air filtration and other functions as one:
Year-round regardless of rain, rain or snow, 24/7 uninterrupted continuous automatic supply of hot water;
Efficient dehumidification, 24 hours a day maximum dehumidification 6~8 kg, plum rain and rainy weather effect is obvious;
Filter indoor air, when installed in the kitchen, the effect is more obvious.
Additional heating accessories, winter can make the indoor temperature above 5℃, so that study, entertainment, sleep more comfortable.
It works at low temperatures
Rain or shine, day or night, as long as there is air, hot water can be made. At room temperature, 180L of hot water can be produced per hour. However, when the weather is cold and the ambient temperature is low, it will decrease slightly. Especially at -10℃ easy to frosting, defrosting problem is the main difference between other brands of heat pumps
Maintenance methods
1. Air source heat pump water heater is a high degree of automation equipment, the use of regular unit status check, if the unit can carry out long-term effective maintenance and maintenance, the operation reliability and service life of the unit will be unexpectedly improved.

Note: Before the first use of the power supply, ensure that the water in the insulated water tank is fully filled.
Common sense
Have occurred
Will scale be produced because air energy water heater - household heat pump water heater uses medium temperature (55℃) and the unique patented technology of "over-flow indirect heating" to produce hot water, will produce a small amount of scale. The general electric water heater is heated at 80-100 ℃, so it is easy to produce scale, which then causes the decrease of thermal efficiency, the increase of electricity consumption, the decrease of water outlet pressure, and even the cause of safety accidents.
Temperature, water consumption
Bath water temperature is the most appropriate 42℃, the elderly can be slightly higher 1-2℃, shower water per person about 40~50 liters. Bathtub and jacuzzi are determined according to capacity.
How much hot water can be made
From the product performance and theory, air energy water heater - household heat pump water heater, can be recycled, continuously produce hot water. At room temperature, hot water can be produced per hour as follows (45℃-55℃): according to the size of the unit.
