Q:Superconducting heat pipe solar collector temperature ok
By the heat pipe itself, the quality and life of the impact of some heat pipe quality degradation and attenuation problems, not easy to be found, and the cost is high, superconducting heat pipe.
Q:What is the working principle of flat solar collectors?
Flat plate solar collector heat plate is flat shape, hence the name. It consists of transparent cover, heat sink, and jacket composed of four parts. The solar radiation passes through the transparent cover of the collector, is projected on the heat absorbing plate, the heat absorbing plate absorbs and converts it into heat energy, and then the heat is transferred to the heat transfer medium in the heat absorbing plate to raise the temperature Useful energy output.
Q:The characteristics of flat solar collectors
Flat solar water heater advantages: First, particularly suitable for integration with the building requirements. Flat solar water heater because of its structural characteristics of the plane, in the integration of solar energy applications, the shape of flexible structure, the design is not subject to the shape or size of the constraints,
Q:Solar collectors and tank water can not cycle what is the reason
pipeline loop problem. If there are other piping behind the pump, pay attention to other pipeline valve opening and closing situation
Q:With the tonnage of solar collectors and air to hot water which power consumption
resulting in no hot water in the rain and snow weather; and air to hot water works relative It is not affected by the sunshine, theoretically can be used throughout the year.
Q:About centralized solar water heater
passes through the solenoid valve or the collecting system circulating water pump under the control of the control system to run automatically, The hot water in the collector will be transferred to the
Q:Condensation type solar collectors and non-concentrating heaters
Non-concentrating collector The non-concentrating collector is a solar collector that does not change the direction of the solar radiation entering the lighting port and does not concentrate on the heat absorber. According to the collector is tracking the sun classification According to the collector whether to track the sun, solar collectors can be divided into two types. The tracking collector is a solar collector that tracks the sun's motion every day around a single or dual axis rotation.
Q:Vacuum tube for solar collectors
Start fast: heat pipe heat capacity, in the sun a few minutes after the output of heat; and in the cloudy weather, than other water heaters can produce more hot water.
Q:The introduction of flat solar water heater
The collector and the water tank are separated from each other. The collector can be flexibly installed on the roof, skylight, balcony or wall, and it is not limited by the position and has reached the perfect combination with the high-rise building and the environment.
Q:Flat solar collector is a good blue film, or good black chrome? It is best to specify.
However, the current plating black chrome process, the current density (15 ~ 200A / dm2), the solution conductivity is poor, plating will produce a lot of Joule heat, cooling and ventilation need to maintain normal production. In addition, the black chrome plated in the non-copper pieces, you need to pre-copper, and then plating bright nickel, and finally black chrome, the higher production costs.
