Abstract

The invention discloses a solar geothermal heating device. The device comprises a solar heat collector, an energy storage heat exchanger, a heat pump set and a user geothermal radiating plate, wherein the energy storage heat exchanger is arranged under the ground; the water outlet of the solar heat collector is connected with the water inlet of the energy storage heat exchanger; the water outlet of the energy storage heat exchanger is connected with the water inlet of the user geothermal radiating plate through the heat pump set; and the water outlet connected with the water inlet of the user geothermal radiating plate is connected with the water inlet of the solar heat collector through a water pump. Compared with the prior art, the solar heat collector is connected with the energy storage heat exchanger in series to store the solar energy absorbed by the heat collector in the shallow soil of the ground surface through the circulation of media and store the solar energy by the heat storage capability of the shallow soil in the non-heating seasons. The solar energy in the heating seasons, stored solar energy and geothermal in the shallow ground can be supplied to users in the heating period.

Description

Solar ground heat heating device
Technical field
The present invention relates generally to the comprehensive utilization of solar energy and geothermal energy, and is significant to alleviating China's heating energy consumption demand.
Background technology
China's heating district heating heating power consumption accounts for more than 65% of total energy consumption of its building, and mainly based on the fossil fuel of coal, utilization ratio is low for the energy.A large amount of uses of fossil fuel have not only aggravated the depleted speed of china natural resources, also have been with serious environmental problem simultaneously.Exploitation underground heat energy storage device utilizes clean reproducible energies such as solar energy and shallow surface geothermal energy to heat, and is significant to the energy strategy of China.
Summary of the invention
The design's invention is primarily aimed at the characteristics that China's heating energy consumption demand is big, the renewable and clean energy resource utilization is few, has developed solar ground heat heating device.This device comprehensive utilization solar energy and geothermal energy heat, and energy consumption is low, and is pollution-free.Utilize energy storage heat exchanger that the storage of solar energy of the whole year is got up to heat and use, the solar energy utilization ratio is higher.
The present invention mainly adopts following scheme:
A kind of solar ground heat heating device, comprise solar thermal collector, energy storage heat exchanger, source pump and user's floor heating radiant panel, described energy storage heat exchanger is arranged on below the face of land, the delivery port of described solar thermal collector is connected with the water inlet of energy storage heat exchanger, the delivery port of energy storage heat exchanger is connected by the water inlet of source pump with user's floor heating radiant panel, and the delivery port that the water inlet of user's floor heating radiant panel connects is connected to the water inlet of solar thermal collector by a water pump.
Compared with prior art, floor heating heating plant of the present invention has following advantage:
1) solar thermal collector is connected with energy storage heat exchanger, and at non-heating season, the storage of solar energy that the circulation by medium absorbs heat collector utilizes the thermal storage effect of thin solum to store solar energy in shallow surface soil.The solar energy of heating season, the solar energy of storage and shallow surface geothermal energy can be used for the user in heating period.
2) in order to guarantee reliability of system operation, this device has fully utilized heat pump techniques.Heat pump techniques is the new energy technology that receives much attention in the whole world in recent years.Heat pump is when work, itself consumes part energy, the energy of storing in the surrounding medium is excavated, improving temperature by the heat-transfer working medium circulatory system utilizes, and the merit that whole heat pump assembly consumed only is the sub-fraction in the output work, therefore, adopt heat pump techniques can save a large amount of high-grade energies.When geothermal energy and solar energy can not satisfy the heating demand, enable heat pump, promote these low taste heat energy and arrive the heating demand.
3) in this device design process, taken into full account the flexibility of system's operation.By the switching of valve, have following heating mode: 1. underground heat is born user's thermic load separately; 2. underground heat is connected with solar thermal collector and is born user's heat load; 3. underground heat is connected with source pump and is born user's heat load; 4. user's heat load is born in underground heat, solar thermal collector and source pump series connection.
4) user adopts radiant panel heating, also can reduce the temperature of hot water when improving thermal comfort for room, improves the fire efficient of system.
Description of drawings
Fig. 1 is the structural representation of invention.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated, as shown in Figure 1, solar ground heat heating device of the present invention, comprise solar thermal collector 1, energy storage heat exchanger 4, source pump 3, water pump 5, user's floor heating radiant panel 2 and a plurality of valve 6, wherein energy storage heat exchanger 4 is arranged on below the face of land and with solar thermal collector 1 and connects, the degree of depth of energy storage heat exchanger 4 with below the face of land 20 meters-50 meters be advisable, the delivery port of energy storage heat exchanger 4 is connected with the water inlet of user's floor heating radiant panel 2 by source pump 3, thereby the thermal source that solar thermal collector 1 is stored in the heat exchanger 4 offers user's floor heating radiant panel 2, the delivery port of user's floor heating radiant panel 2 is connected to the water inlet of solar thermal collector 1 by water pump 5, and wherein energy storage heat exchanger 1 can be adopted as heat exchange coil.
