Heating arrangement for heating a fluid utilizing a solar panel

Abstract

The present invention relates to a heating arrangement for heating a fluid, comprising a first heat exchanger loop (5), arranged to act on a fluid to be heated, and a second heat exchanger loop (8), arranged to also act on said fluid to be heated, wherein said second heat exchanger loop (8) is connected to a panel (4) that serves as a solar collector and that is arranged to heat at least a part of said second heat exchanger loop (8).

Description

technical field [0001] The invention relates to a heating device for heating a liquid comprising a first heat exchanger circuit arranged to act on the liquid to be heated and a second heat exchanger circuit arranged to also act on said liquid to be heated. Background technique [0002] Various heating devices are known in the field of heating liquids, such as building water. In a house, water used as tap water needs to be heated to a suitable temperature and stored in a tank for use when needed, and supplying such heated water by conventional methods is usually expensive. [0003] To reduce costs, renewable energy sources such as solar panels can be used, however, in colder climates it is often difficult to meet the energy requirements for heating tap water year-round due to the size of the solar panels required and their associated costs. However, solar panels, which are necessary in winter, are not needed in bright summer months, resulting in redundant heating systems and...

AI Technical Summary

Problems solved by technology

In a house, water used as tap water needs to be heated to the right temperature and stored in tanks for use when needed, and supplying such heated water through traditional methods is often expensive

[0003] Renewable energy sources such as solar panels can be used to reduce costs, however, in colder climates it is often difficult to meet the year-round energy demand for heating tap water due to the size of the solar panels required and their associated costs

However, solar panels, which are necessary in winter, are not needed in bright summer months, resulting in redundant heating systems and excess energy for heating water

As a result, the liquid in the solar panel is heated to a boil causing damage and the risk of freezing damage in winter

[0004] Some systems are known to solve these problems, however, most of these systems are too expensive and bulky for consumers living in smaller homes

In many houses, air-to-air heat pumps are installed to heat the indoor air, while air-to-water heat pumps are also used to heat tap water and / or water from radiators, etc. They are more expensive and are not used

In addition, for homes where heating systems are already in place, retrofitting heating systems more efficiently is inherently expensive and thus disadvantageous to consumers

[0005] Another problem faced by users of such installations is the need for defrosting in colder climates in order to avoid unacceptable loss of efficiency due to icing on installation components

Defrost usually requires a lot of energy and the unit must not heat the water during the defrost operation causing further losses
