Flat plate solar return water pump

What is a flat plate solar water heating system?

Flat plate solar water heating system characteristic: 1. No disorder water tank on roof 2. Pressure hot water, comfort bathing/washing 3. Collector module designed for freely assemble 4. Completely automatic operation. 5. Can be combined with traditional auxiliary energy resource 6.

How does a solar heat pump work?

When the large flat plate solar collector can only raise the water tank temperature by 15 to 35 °C, the hot water flows into the shell and tube evaporator of the heat pump unit through valve 2, increasing the evaporating temperature and pressure. The solar heat pump function raises the water temperature above 35 °C for heating the single building.

What is a flat plate solar collector?

Compared with vacuum tube solar collectors, flat plate solar collectors are arranged as a whole, with a high degree of integration with the building, and the heat-absorbing medium is circulated in the internal copper tubes for better pressure-bearing capacity.

What fluid does a solar collector use?

Fluid The fluid that circulates through your solar collectors is known as the HTF or Heat Transfer Fluid. Your HTF can be either water (potable water in an open loop system) or a water-glycol solution. A water glycol solution can protect flat plates from freezing in temperatures far below zero if need be.

What makes a good solar heat pump system?

Good system design and combination are the key to achieving good performance. The design and selection of solar collectors and heat pumps has an important impact on the performance and economic efficiency of the system. As we all know, solar heat pump includes direct and indirect expansion .

What is a large flat plate solar collector (lfpsc)?

Therefore, the Large flat plate solar collectors (LFPSC), which refers to a single flat-plate solar collector with a large heat collecting area, has become a new trend in the development of solar thermal utilization.
