Abstract
The invention relates to a system using the urban sewage as the refrigerating or heating source of an absorption type refrigerating and heating water unit. The system can use the steam, heating water or flue gas type absorption type refrigerating and heating water unit, and use the urban sewage as a heating or refrigeration supply system of the low-temperature heating or refrigerating source. When heating, the absorption type refrigerating and heating water unit is driven by steam, heating water, flue gas and other heat sources containing high-temperature heat, and the heating water is prepared by extracting low-quality heat in the urban sewage so as to supply heat for a building. When refrigerating, the absorption type refrigerating and heating water unit is driven by steam, heating water, flue gas and other heat sources containing high-temperature heat, the heat radiation is implemented by the urban sewage. The system improves the unit efficiency when being refrigerated and heated, uses renewable energy resources as the low-temperature heat source, thereby having important significance for relieving energy shortage of our country and developing circular economy.
Description
Affiliated technical field
The present invention relates to the absorption-type cold-hot water dispenser group when heat supply/cooling, is the system of low-temperature heat source or low-temperature receiver with the municipal sewage.
Background technology
Generally, the absorption-type cold-hot water dispenser group drives by the thermal source that steam, hot water, flue gas etc. contain heat of high temperature, and cooling water dispels the heat by cooling tower during refrigeration, and coolant water temperature is 25 ℃-35 ℃.From low-temperature heat sources such as air, extract tow taste heat when heating.According to the performance of absorption-type cold-hot water dispenser group, in certain temperature range, cooling water temperature in summer water temperature low more, the winter low temperature thermal source is high more, and unit efficiency is high more.
Contain a large amount of heat energy in the municipal sewage, the sewage temperature that common northern city enters sewer winter is about 10 ℃, and is higher and constant than the temperature of thermals source such as air; Be about 22 ℃ summer, lower than the cooling water temperature after the cooling tower heat radiation.Hence one can see that, as utilize municipal sewage for the cold/heat source of absorption-type cold-hot water dispenser group will improve the efficient of unit greatly, makes it more energy-conservation.
At present, electronic compression sewage source heat pump unit relies on municipal sewage, summer with the transfer of heat in the building in the water source, because the water source temperature is low, so can take away heat in the building efficiently, then extract energy winter from the water source, according to heat pump principle, will deliver to heating in the building after the lifting of circulation heating coolant-temperature gage.
The sewage source heat pump system Energy Efficiency Ratio is higher, yet because sewage source heat pump drives by electricity, uses this system unreasonable to the place that has steam more than needed, hot water, flue gas.
Application number is 02159992.0 patent of invention, and is similar to the present invention.It is a kind of be the heat supply method and the modifying device thereof of water resource heat pump with the direct combustion machine, relate to the improvement of the purposes and the structure thereof of direct combustion machine.The method step of this invention is: (1) is the energy with the natural gas, makes the burning of direct combustion machine; (2) 10 ℃-15 ℃ underground well water is sent in the evaporimeter of direct combustion machine by water pump, returned underground when making water temperature drop to 5 ℃-8 ℃; (3) 40 ℃ warm water is sent in the direct combustion machine absorber by water pump, the condenser by the direct combustion machine when making water temperature rise to 50 ℃-55 ℃ is displaced into user's heat supply.
This invention has following some limitation: 1, the main frame of system is to be the direct combustion machine of the energy with the natural gas, 2, this invention only is used in the heating system, and 3, the low-temperature heat source of system is underground water, and is stronger to phreatic dependence, some urban groundwater deficiency, this system then can't use.
Summary of the invention
Native system can use steam type, hot-water type or flue gas type absorption-type cold-hot water dispenser group, utilizes the heat supply/cooling system of municipal sewage for low temperature hot/cold source, not only available different unit, and make unit that stable cold/heat source arranged.
The technical solution used in the present invention is: system and device is by steam type, hot-water type or flue gas type absorption-type cold-hot water dispenser group, high temperature heat source, and building, municipal sewage, various water pumps, various pipelines are formed.When this system heated, the thermal source that contains heat of high temperature by steam, hot water, flue gas etc. drove the absorption-type cold-hot water dispenser group, and by the tow taste heat in the municipal sewage, preparation hot water is to space heating.During refrigeration, the thermal source that contains heat of high temperature by steam, hot water, flue gas etc. drives the absorption-type cold-hot water dispenser group, and by the municipal sewage heat radiation, relative and cooling tower owing to reduced the condensation end water temperature, improves unit efficiency greatly.
The invention has the beneficial effects as follows: during heat supply, utilize the higher relatively municipal sewage of temperature to be low-temperature heat source, improve the unit operating efficiency; During refrigeration, utilize the lower municipal sewage of relative outside air temperature to do low-temperature receiver, can reduce the high temperature heat source supply, improve unit efficiency.Develop a circular economy significant to alleviating China's energy shortage.
