Abstract
The invention relates to a heat supplying and oxygen enrichment integrated heat pump assembly for aquaculture. The heat supplying and oxygen enrichment integrated heat pump assembly for the aquaculture comprises a water source heat exchanger, a throttling device, an air source heat exchanger, an axial flow fan, a four-way reversing valve, a compressor, a buffer water tank, a first stop valve, a heat exchange water pipe, a second stop valve, a water pump, an air blower and an air pipe, wherein all the components form assemblies including a refrigerant circulation system, an oxygen enrichment system, a water source circuit and an air source circuit. The heat supplying and oxygen enrichment integrated heat pump assembly for the aquaculture further comprises internal pipelines connected together and a detection control system. The heat supplying and oxygen enrichment integrated heat pump assembly for the aquaculture uses heat pumps to replace a boiler for supplying heat to or refrigeratinga pond used in the aquaculture, and is usually equipped with the small air blower to increase content of dissolved oxygen in pond water. Compared with the prior art, the heat supplying and oxygen enrichment integrated heat pump assembly for the aquaculture has the advantages that when compared with a boiler heating mode, the heat supplying and oxygen enrichment integrated heat pump assembly for the aquaculture is low in carbon, environmentally friendly and efficient, and further has a refrigeration function in summer, and the air flower arranged in the heat supplying and oxygen enrichment integrated heat pump assembly for the aquaculture greatly reduces loss in a long distance output air pipe, and improves usage rate of energy source.
Description
technical field [0001] The invention relates to a heating and oxygenation device, in particular to an integrated heat pump unit for heating and oxygenation for aquaculture. Background technique [0002] Heating and oxygenation are very important for winter aquaculture. Traditional heating methods use coal-fired boilers or gas-fired boilers. Coal-fired boilers use low-quality coal with low calorific value and high ash content. The incomplete combustion of coal produces a large amount of soot and sulfur dioxide, which pollutes the atmospheric environment. Some areas have begun to completely ban s. The operating cost of gas-fired boilers is extremely high, which greatly reduces the profit margins of farmers. Therefore, there is an urgent need for a new and efficient heating method to replace boiler heating. The traditional way of increasing oxygen is to use a large blower to blow air into dozens of ponds through pipelines, so that the water body convects up and down, and the ...
