Patent Name: Medium and High Temperature Heat Pump Device
Inventor: Nye
Patent number: ZL 00 1 36774.9
The medium and high temperature heat pump device has four key components: compressor, condenser, evaporator and expansion valve. Supercooler and special expansion valve are components to improve energy efficiency ratio. According to the invention, a non-boiling multicomponent mixed working medium with low environmental damage is adopted, and one of different combined working mediums is injected into a heat pump device, so that the evaporation temperature is about 25 DEG C, the condensation temperature is above 80 DEG C, the condensation pressure is below 24bar, and the system energy efficiency ratio is above 3. The drainage of about 40℃ can be reduced to below 30℃, and the heating water temperature can be increased to above 70℃, up to 88℃.
Patent name: portable seawater desalination heat pump system
Inventor: Nye
Patent number: ZL 2004 1 00 18776.2.
The invention relates to a system for seawater desalination and water treatment by using heat pump technology. The invention mainly consists of a compressor, a condenser, a capillary tube, an evaporator, an axial fan and the like, and the above components (except the axial fan) are connected in series and divided into an upper part, a middle part and a lower part to form an open system; When seawater is heated by the coil condenser, the steam is condensed by the forced convection evaporator, and the heat is transferred from low-temperature steam to high-temperature seawater through the circulating working medium in the heat pump device, thus maintaining a certain temperature difference and completing seawater desalination. The invention has the advantages of high operation efficiency, high seawater desalination speed, small occupied area, strong maneuverability, convenient installation and maintenance, low noise and the ability to purify and treat some types of sewage. If the compressor with rated input power of 0.8 kW is used, the device can produce more than 3.6kg of fresh water per hour, which can be used for emergency and maintenance of 1-2 people a day.
