    • In heating and cooling with a bifunctional, flexible solar collector made entirely from plastics, and the appts. used, the novel features are that the solar collector has a flexible synthetic fibre solar absorber with a heat-conducting microporous coating, hermetically sealed in a completely plastics housing. The solar absorber has interconnected plastics tubes, covered and in conductive contact with a heat-conducting, black and micorporous coating. The housing is a UV-resistant, transparent housing with antireflective properties. The bottom insulating mat pref is hermetically sealed against moisture in a plastics bag. The thermal insulation can be increased by using a UV-resistant and transparent air chamber film. The collector can be placed over a sealable exhaustion device for removing col vapour in one junction setting; pref. over a hollow profile frame for collector stabilisation, receiver for cold condensed liquir and supply or liquid to the capillaries; esp. a steam chamber covered by plastics film stretched over profiles.
