The use of heat-absorbing medium inside the device (refrigerant) from the air or natural environment to collect heat, and through the heat exchanger so that cold water rapidly warming, while the discharge of cold air. Avoiding the defects that traditional solar products can not work in rainy and rainy days or night can work normally when the outside temperature is above -15 DEG C so that the utility model can be more efficient and energy-saving without occupying the open space. The utility model has the advantages of simple installation and flexible use.
The unit constitutes a mode of operation and principle
Heat pump water heater is composed of a refrigeration cycle, including the host and the condenser in two parts. The host part includes evaporator, fan, compressor and expansion valve; the condenser is an incubator with condensing coil inside. The refrigerant absorbs the heat of the outside air in the evaporator, releases heat within the condensing coil by the heat pump cycle, and heats the water in the tank. Water tank insulation with closed-cell rubber sponge or polyurethane foam, today's focus:
And has good insulation properties.
Heat pump unit equipment set a heat-absorbing medium - refrigerant, which liquefied state at room temperature below minus 20 ℃, so there is temperature difference with the outside world, the refrigerant absorbs the outside temperature, generated inside the evaporator Pressure and evaporative evaporation, through the heat exchanger (heat pump) work, the refrigerant from the vaporized state into liquefaction state, the objective of the heat will be released to the storage tank water. Electricity is only used to make the heat released, rather than used in the direct heating, so the use of electrical very few, in the summer when the temperature is high, the production of a ton of hot water loss of about 5-6 kWh, cold winter weather loss of about 20 --25 degrees electricity, the annual average does not exceed 15 degrees electricity.
Product features
A wide range of sources of heat, including sunlight, rain and air. Regardless of the day and night; regardless of sunny days, wind and rain, snow can work as usual, free from the impact of the weather, all-weather throughout the year to work;
Can be placed anywhere you specify, does not affect the appearance of the building, with little space, no direct light, the installation is very easy. Can be placed in the open, but also can be placed in inconspicuous corners or the basement, and can achieve unmanned operation, automatic temperature control water supply;
Can be used in hotels, restaurants, factories, schools, hospitals, saunas, beauty salons, swimming pools, greenhouses, farms, laundries, homes, etc., can be used alone, can also be used separately, different heating Requirements, choose a different product line and installation design, but also free access to air-conditioning, from any angle to meet your requirements;
Excellent CFC-free insulation with only 2% heat loss, longer water temperature, and thermal efficiency over other conventional solar products. Free refrigerant freon, without any exhaust gas, waste water discharge, absolute environmental protection, no gas or electric tank to promote, absolutely safe.
Energy-saving effect is obvious, compared with the use of fuel oil, gas, electricity, coal, etc., can save at least 75% of operating costs, allowing you to easily recover the cost.
Product Features
High efficiency and energy saving: The hot water unit takes hot air with low temperature and air as heat source, and consumes only 1 / 3-1 / 4 of the electric water heater. Compared with coal, oil and gas hot water units, it can save 75% Operating costs.
Environmentally friendly and pollution-free: The system operates without any combustions and emissions and is a sustainable and environmentally friendly product.
Safe and reliable operation: the whole system is running without the danger of flammable, explosive, poisoning and short circuit which may exist in the traditional water heater (fuel or gas or electric water heater). It is a safe and reliable hot water system.
Long service life, low maintenance costs. Comfortable and convenient, automated, high degree of intelligence.
Investment Casting Lost Wax Casting
Investment casting, which is also known lost wax casting or precision casting, refers to the formation of ceramic around the wax patterns to create a multi or single part mold to receive molten metal. This process utilizes an expendable injection molded wax pattern process to achieve complex forms with exceptional surface qualities. To create a mold, a wax pattern, or cluster of patterns, is dipped into ceramic material several times to build a thick shell. Die-wax process is then followed by the shell dry process. The wax-less ceramic shell is then produced. Molten metal is then poured into the ceramic shell cavities or cluster, and once solid and cooled, the ceramic shell is broken off to reveal the final cast metal object. Investment castings can achieve exceptional accuracy for both small and large castings in a wide range of materials.
