The invention discloses a seawater desalination system adopting combined operation of a solar collector and a seawater-source heat pump. The system comprises the solar collector and a seawater-source heat pump unit, wherein the seawater-source heat pump unit comprises a seawater-source heat pump evaporator, a seawater-source heat pump compressor, a seawater-source heat pump condenser and a seawater-source heat pump electronic expansion valve. The seawater desalination system has the advantages of small overall size, simple structure, portability, convenience in transportation and initial cost saving; solar energy as a rich renewable energy source in a sea island is used, energy saving and environmental protection are realized, and the cost is low; fresh water can be prepared through a simple physical process, low requirements are needed for seawater pretreatment, a fresh water preparation process is safe and reliable, and the service life is long; an air-air heat exchanger is taken as an energy recovery device, energy waste can be avoided, and the energy utilization rate can be increased; when residents on the sea island adopt the seawater-source heat pump as a building cooling and heating source, and the system shares the seawater-source heat pump, so that the initial cost is saved again.
Description
technical field [0001] The invention relates to a seawater desalination technology, more specifically, the invention relates to a seawater desalination system in which a solar heat collector and a seawater source heat pump operate jointly. Background technique [0002] my country is a large ocean country with many islands. According to statistics, in my country, there are 6,921 islands with an area larger than 500 square meters, and nearly 10,000 islands and rocks with an area of less than 500 square meters. These islands are rich in resources and special in location, which is an important support for my country's economic and social development. The use and development of island resources requires people to go to the island, and the most important and urgent problem faced by the people who go to the island to work and live on the island is to solve the supply of fresh water. [0003] As we all know, there are no rivers, rivers, groundwater and other fresh water resource...
