The invention discloses a double-unit series heat
recovery system, relates to the technical field of heat
recovery, and aims to solve the problem that most heat in an existing
heat pump is directly radiated to the outside in a heat
radiation mode, and consequently serious waste is caused. According to the
system, a first mounting plate is mounted at the upper end of one side in a body bracket, a compressor is mounted at the upper end of the first mounting plate, and a
water storage tank is mounted on the other side in the body bracket and is fixedly connected with the body bracket; and the
water storage tank comprises heat preservation
sponge, heat insulation rubber, an outer
isolation layer, a heat conduction layer, a supporting bracket and a
hot water storage tank, the heat insulation rubber, the outer
isolation layer, the heat conduction layer, the supporting bracket and the
hot water storage tank sequentially adjoins the inner side of the heat preservation
sponge, the heat preservation
sponge is connected with the heat insulation rubber and the outer
isolation layer adjacently in a glued mode, the outer isolation layer is fixedly connected with the heat conduction layer through a supporting plate, and the heat conduction layer, the supporting bracket and the
hot water storage tank are adjacently connected in a welded mode.
