Ultrahigh-temperature heat pump device with heat source recovery

Abstract

The invention relates to an ultrahigh-temperature heat pump device with heat source recovery. A compressor, an oil separator, a condenser, a supercooler and an evaporator are connected in sequence through pipelines to form a loop; a throttling device is arranged between the supercooler and the evaporator; the compressor, the oil separator, an oil storage tank and an oil cooler are connected in sequence through pipelines to form a loop; the oil cooler is connected with the compressor through a main oil way electromagnetic valve and an oil way adjusting valve in sequence; the evaporator is provided with an evaporator water inlet and an evaporator water outlet; the supercooler is respectively connected with a water inlet of the evaporator and a water outlet of the evaporator through pipelines; and the oil cooler is respectively connected with the water inlet of the evaporator and the water outlet of the evaporator through pipelines. The device can use low-temperature afterheat and waste heat sources for preparing high-temperature hot water with the highest temperature of 122 DEG C, so that the operation cost is low, no pollution is discharged, the energy conservation and the environmental protection are achieved, and the heat pump system efficiency is higher.

Description

technical field [0001] The invention relates to a heat pump device, in particular to an ultra-high temperature heat pump device with heat source recovery. Background technique [0002] In recent years, China's environmental pollution has intensified, and smog has seriously affected people's health and daily life. A major source of PM2.5 is the burning of coal. According to the data provided by the China Statistical Yearbook in 2013, the proportion of coal in the total energy production has been between 76 and 77% over the years, the proportion of fuel oil has been between 9 and 14%, and the proportion of natural gas usage has been increasing year by year. It was also only 4.3% in 2012. my country's energy structure has not yet got rid of the status quo of highly polluting energy. The consumption of fossil energy is mainly used in the three fields of industrial smelting, combustion power generation and building heating, each accounting for about 1 / 3 of the total. Among th...

Problems solved by technology

At present, the source of industrial hot water is mainly traditional coal-fired oil-fired boilers, which have low thermal efficiency and emit a large amount of carbon dioxide, nitrogen oxides, sulfur dioxide, dust, etc. also pose a safety hazard

In order to solve the serious pollution problem mentioned above, researchers have developed an environmentally friendly and energy-saving heat pump system. Generally, water source heat pumps use electricity as energy, and use low-grade waste heat, geothermal and other free heat sources to replace coal-fired gas boilers to produce hot water. The efficiency is low when the water temperature difference is high, and the water temperature is rarely above 90°C
