The invention discloses an energy-saving air energy
refrigeration heat exchanger, and belongs to the technical field of air energy equipment. The energy-saving air energy
refrigeration heat exchangercomprises a main
machine. The left side surface of the main
machine communicates with the right side surface of a water tank through a cold water pipeline and a hot water pipeline, and the upper surface of the water tank is fixedly connected with the lower surface of a bottom plate. A tank body, an air bag, an
air chamber, an inflating device and a
flange plate are arranged, when the main machineand the water tank are in a normal working state, water is transmitted into the air bag through a connecting device, and the pressure between the air bag filled with water and the
air chamber reachesa
balance point. When the external temperature of the water tank changes and the
internal pressure of the water tank decreases, the process of water replenishment is required, water in the air bag canbe squeezed out and supplied to the water tank until the pressure in the water tank recovers, and
dynamic balance in the water tank is maintained. The main
machine and the water tank are prevented from being started again in the small-amount water supplementing process, the starting and stopping frequency of the main machine and the water tank is reduced, a large amount of
electric energy is saved, and the service life of the main machine can be prolonged.
