It has successively become a large brand engineering partner such as Linuo Solar, Sanle Solar, Midea Air Source Heat Pump, Tsinghua Tongfang Ground Source Heat Pump, etc. , Undertook a large number of large-scale solar hot water demonstration projects in hotels and communities, and formally became the general distributor of Midea air source heat pumps in North China in December 2007. The remote automatic control system has been successfully applied to more than 230 hotels, schools, real estate and other major hot water engineering projects, and the automation management application technology has become increasingly mature.

The company is insisting

Solar hot water comes from nature, with pure water quality, stable temperature rise, and no pollution such as ionization and electrolysis. It is called natural hot spring. According to historical records, Guan Yunchang and Liu Bei separated in the Three Kingdoms, escorted Mrs. Gan and Mi to Jingzhou, and in order to solve the problem of bathing Mrs. Guan Yunchang asked her subordinates to ride on the water with a bucket of mato and was exposed to the sun during the day. After staying at the store at night, you can use these two buckets of water to bathe the two ladies. Later, after finding Liu Bei, Mrs. Liu Guan's complexion had no tiredness on the journey, but the skin was tender and tender, so the folks in Henan rumored that the sun water can be beauty. As for whether the solar water heater has a beauty effect, scientific principles have yet to confirm. It is an indisputable fact that using solar hot water to wash and wash dishes has protected the skin on the hands of women and kept them tender.

The water tank, bracket and shell of the solar water heater are made of high-quality stainless steel and aluminum alloy profiles. Can withstand long-term open-air operation.

I. Installation and Construction

1. According to the situation of the user's room, determine the fixed position of the host. The main unit should be installed on a wall with a height of not less than 1.4m from the ground and convenient for user operation.

2. When hitting expansion bolts or steel nails on the wall, avoid the wires buried in the wall.

3. Wiring laying: It should meet the requirements of national standards.

(1) Lay PVC rigid plastic pipe, or apply it outdoors. Do not lay in places with high temperature and mechanical damage.

(2) The connection of hard plastic pipe must be firm and sealed. The exposed hard plastic pipe shall be protected by steel pipes in places where the floor is vulnerable to mechanical damage, and the protection height shall not be less than 0.5m.

(3) The distance between the fixing points should be even when the plastic pipe is exposed. The distance between the pipe card and the terminal turning midpoint is 0.15-0.5m, and the maximum distance between the intermediate pipe cards is 1 meter.

(4) There must be no joints or kinks in the wire. The fixed distance of the line card when the plastic sheath line is exposed is not more than 0.3m.

(5) After the hard plastic wire tube is applied to the solar water heater bracket, it must be waterproof bent. A section of the cable from the waterproof bend to the junction box of the electric heater must be protected by a corrugated pipe.

4. Sheath wire is connected with electric heater and host.

(1) The core should not be damaged when the insulation layer of the wire is cut. The wires connected to the heater must be tinned or treated as crimp ends.

(2) The wires of corresponding colors shall be crimped in accordance with the NL and ground symbols marked on the heater terminal.

(3) The host is connected by a three-pole plug and a sheath wire. When crimping the wire according to the NL and ground symbol on the three-pole plug, it must correspond to the wires on the crimping terminal of the heater to prevent short-circuit accidents caused by the crimping wire.

5. Water temperature and water level and the connection of various signal wires refer to the installation instructions of various products.

Second, power transmission inspection

1. The user's original indoor wiring should meet the following requirements:

(1) Use a 1.5kW electric heater. The cross-section of the original indoor wiring should be no less than 1.5 square millimeters of copper core wire and no less than 4 square millimeters of aluminum core wire.

(2) A three-pole socket with protective ground is required to connect to the host. The capacity of the socket must not be less than 250V, 10A.

2. Turn on the "power switch" of the host, so that the host can correctly display the water temperature and level.

3. Start the electric heating to see if the function is effective. Press the "Experiment Button" to check whether the leakage protection function is sensitive and reliable.

4. Check the solenoid valve water stop function.

5. Check the power outage function: For products with this function, when there is a sufficient amount of water in the water tank, turn on the electric heating. While turning on the faucet, observe whether the word "electrical heat" disappears immediately and whether the power is automatically turned off.

6. Check the automatic anti-freeze function: For products with this function, when the ambient temperature is lower than 0 , the main unit relay will have a closing sound, and then pressing the "electric heating" button temporarily does not work, indicating that the machine is performing the anti-freeze function.

Third, use introduction

1. In order to ensure the service life of the host and the sensor, the "power switch" should be turned off at any time when not operating, except for fully automatic control instrument products.

2. Check the leakage protection function, and check the function at least once a month during use.

3. Using a 1.5kW electric heater, for 100 liters of water, it can increase by about 10 ° C in 1 hour.

4. Don't forget to close the valve when using manual valve to fill or adjust the water temperature.

Large solar manufacturers are selected for solar water heaters, and generally have thermal insulation and antifreeze measures, which are well installed and guaranteed after sales.

If you are near the top floor, you can install a solar water heater. If your home uses a lot of hot water, such as washing vegetables, cooking clothes, etc., it is recommended that you install a solar water heater to save power.

First look at the floor. If it is too low, it is not recommended to install solar energy.

If the floor is low and the water consumption is not very large, use an electric water heater, 50 litres for a household of 3 mouths is sufficient, and 60 litres for a household of 5 mouths or a little larger.

In general, the service life of solar energy is the same as that of electric water heaters. Although the initial investment is large, the electricity costs saved in 3-5 years will be recovered. The volume of domestic electric water heater is generally 40L, and the minimum solar energy is about 150L.

In the north, there is a large amount of water in winter. Washing clothes, vegetables, and cooking all require hot water. Solar water temperature is about 40-60 degrees in winter and 80-99 degrees in summer, which is enough for domestic water. The solar water heater has a heat insulation function to prevent freezing on the pipes. A 100 yuan electricity bill for 4 months is enough. It also has an electric heating function, which consumes almost the same power as an electric water heater (basically not used).

Long-term consideration of installing solar energy still saves money.

Solar water heater water tanks can generally be inspected by the Technical Supervision Bureau. If you want to identify with the naked eye, you can only see parts. You can roughly look at these aspects:

1. Thickness and materials of the outer cylinder skin;

2, the thickness of the liner;

3. Thickness and density of insulation layer;

4. The weight of the overall water tank.
