Abstract
The utility model belongs to a device which uses a solar auxiliary electric heater for heat storage of shallow soil, in particular to a solar auxiliary electric heating heat storage device for an earth source heat pump, which comprises a soil heat exchanger buried in a heat exchange well through a backfilling material, the soil heat exchanger is connected with the earth source heat pump through a water supply pipeline and a water return pipeline, the earth source heat pump is connected with a user terminal through the water supply pipeline and the water return pipeline to form a circulation loop, and the water supply pipeline and the water return pipeline of the solar auxiliary electric heater formed by a solar water heater and an electric heater are connected with a water return pipeline between the earth source heat pump and the soil heat exchanger. The utility model can not only store heat for the shallow soil through the solar heat collector in air-conditioning seasons with relatively adequate sunshine, but also store heat for the shallow soil even when the weather is bad in heating seasons, so as to ensure the long-term and high-efficiency running of the earth source heat pump.
Description
Technical field
The utility model belongs to and utilizes the device of solar energy auxiliary electric heater unit for the thin solum accumulation of heat, especially for the solar energy auxiliary electrical heating regenerative apparatus of earth source heat pump.
Background technology
Earth source heat pump is a kind of energy-saving and environmental protection of rising in China in recent years, economic heating air conditioning technology.Utilize the fuel heating system to compare with tradition, earth source heat pump has advantages such as no CO2 emission, smokeless; Compare with traditional water-cooled or air-cooled air-conditioning, earth source heat pump does not have tropical island effect, the running efficiency of system height; And at cold district, the building and heating air-conditioning all can utilize earth source heat pump, and a tractor serves several purposes has been saved initial cost, and the whole year operation expense is lower.
Earth source heat pump is exactly because annual thin solum energy budget imbalance causes the thin solum temperature to reduce year by year at the maximum bottleneck of cold district development.Because the thin solum of Cooling and Heat Source is provided for earth source heat pump; energy source is in solar illuminating; water content is low; the heat transmission is very slow; temperature reduces the back and is difficult for recovering; thereby make the work that earth source heat pump can't be permanently effective, therefore how to solve the energy budget imbalance problem of thin solum, become this technical field problem demanding prompt solution.A kind of " solar heat-preservation heating cooling method and device " arranged, can carry out accumulation of heat to thin solum season at air-conditioning, but in cold district winter, especially at the moon snow weather, the solar heat-preservation system can't operate as normal, cause the solar heat-preservation system to carry out, can not guarantee the thin solum temperature that the earth source heat pump operate as normal is required, make the earth source heat pump cisco unity malfunction.
Summary of the invention
The purpose of this utility model is to provide a kind of solar energy auxiliary electrical heating regenerative apparatus that is used for earth source heat pump, not only in sunshine air-conditioning season fully, can be by solar thermal collector to the thin solum accumulation of heat, and in heating season during bad weather, still can guarantee the long-term efficient operation of earth source heat pump unit to the thin solum accumulation of heat.
The object of the present invention is achieved like this: a kind of solar energy auxiliary electrical heating regenerative apparatus that is used for earth source heat pump, be included in the heat exchange well and burying the soil heat exchange device by backfilling material, the soil heat exchange device connects the source heat pump that lands by confession, water return pipeline, earth source heat pump is by for, water return pipeline and the terminal formation of user closed circuit, and the confession of the solar energy electrical auxiliary heater that is made of solar water heater and electric heater, water return pipeline are connected with water return pipeline between earth source heat pump and the soil heat exchange device.
In sunshine air-conditioning season fully, the utility model provides hot water by the solar water heater of solar auxiliary heater to the soil heat exchange device, and thin solum is carried out accumulation of heat; When detecting water temperature, the water temperature measuring point in the water tank is lower than when setting value, electric heater circuit switching closure, and the water by in the electric heater heating solar water heater water tank provides hot water to the soil heat exchange device, and heat is stored in the thin solum.When the water temperature in the water tank reaches setting value, the automatic disconnection of electric heater loop.The water temperature setting value can specifically be set according to source pump and local solar irradiation situation.So just can guarantee the thin solum temperature that the earth source heat pump operate as normal is required.By the solar energy electrical auxiliary heater, guaranteed the long-term efficient operation of earth source heat pump unit.Therefore, the utility model is not only in sunshine air-conditioning season fully, can be by solar thermal collector to the thin solum accumulation of heat, and, still can guarantee the long-term efficient operation of earth source heat pump unit to the thin solum accumulation of heat in heating season during bad weather.
