Multi-energy complementary heat pump intelligent heating system with low-grade waste heat recovery function

Abstract

The invention discloses a multi-energy complementary heat pump intelligent heating system with a low-grade waste heat recovery function. The system comprises a wind-driven generator, a first vacuum tube solar heat collector, a low-grade waste heat network and a second vacuum tube solar heat collector; the output end of the wind-driven generator is connected with an electric water heater, and the electric water heater is connected with a heat storage water tank through a first water inlet pipe and a first water outlet pipe; the first water inlet pipe is provided with a stop valve V1, and the first water outlet pipe is provided with a stop valve V2 and a first circulating pump; the output end of the first vacuum tube solar heat collector is connected with a solar constant-temperature biogasdigester, and the output end of the solar constant-temperature biogas digester is connected with a gas storage device; the output end of the low-grade waste heat network is connected with a low-gradeconstant-temperature biogas digester, and the output end of the low-grade constant-temperature biogas digester is connected with the gas storage device; the output end of the gas storage device is connected with a biogas hot water tank; the biogas hot water tank is connected with the heat storage water tank through a second water inlet pipe and a second water outlet pipe.

Description

technical field [0001] The invention relates to the field of heating systems, in particular to a multi-energy complementary heat pump intelligent heating system with low-grade waste heat recovery. Background technique [0002] Disadvantages of existing heating systems: [0003] 1. There are strict weather conditions for solar energy, wind energy, and air heat energy to produce biogas to provide heat energy. [0004] 2. Weather changes will cause the heating system to be unstable, and there is no supplement of various energy sources. [0005] 3. It cannot be sensed and adjusted to the most energy-saving correct working mode. [0006] 4. Different users have different requirements for temperature, and the existing heating system cannot adjust the room temperature according to the actual needs of customers. Contents of the invention [0007] The purpose of the present invention is to provide a multi-energy complementary heat pump intelligent heating system with low-grade w...
