Problems solved by technology

However, from the perspective of energy saving, it can be found that such a solution will bring some problems, that is, the process of heat exchange and pressurization of the hot water used in the high and low areas will cause energy loss on the one hand, and on the other hand The increase of heat exchange and pressurization equipment will also increase the initial investment cost, which is contrary to the original intention of research and development of renewable energy

Embodiment 1

[0048] The traditional high and low district heating system with ground source heat pump as heat source described in the background of the present invention, such as figure 1 As shown, the hot water from the heat source well 13 enters the evaporator 12 in the heat pump unit 1 through the heat source side circulation pump 7, and provides a heat source for the high-temperature heat medium passing into the condenser 11, and the heating return water in the condenser 11 After exchanging heat with the high-temperature heat medium to improve the thermal quality, the outlet water from the condenser 11 is divided into two paths and sent to the high-zone heat exchanger 2 and the low-zone heat exchanger 3 respectively, and then passes through the residential high-zone circulation pump 6 and the residential low-zone heat exchanger respectively. District circulation pump 5 sends to heating users in high and low districts.

[0049] The present invention provides a high and low district heat...

Embodiment 2

[0055] The present invention uses a ground source heat pump as a heating method for high and low zones, comprising the following steps:

[0056] a. The hot water in the heat source well 13 is supplied to the evaporator of the heat pump unit 1 through the heat source side circulation pump 7 to provide heat, and the hot water released by the evaporator is injected into the heat source well 13 through the pipeline to complete the circulation on the heating side ;

[0057] b. The heat medium in the evaporator is heated by hot water and then circulated to the condenser. After the high-temperature heat medium releases heat in the condenser and cools down, it returns to the evaporator to heat again to complete the heat exchange;

[0058] c. Two sets of independent water systems in the same condenser are heated by exothermic high-temperature heat medium, and then respectively pass through the high-zone circulation pump 6 and the low-zone circulation pump 5 to provide heating for high-...

Abstract

The invention relates to the field of application of new energy, in particular to a high-low area separated heating system and method using a ground source heat pump as a heat source. The system comprises a heat source well, a heat source side circulating pump, a heat pump unit, a low area circulating pump and a high area circulating pump, wherein the heat source well, the heat source side circulating pump and the heat pump unit are arranged on a heat supply side; the low area circulating pump and the high area circulating pump are arranged on a heating side; the heat pump unit comprises a condenser and an evaporator which communicate with each other through a heat medium loop; a water inlet of the evaporator is connected with a water outlet of the heat source side circulating pump througha water inlet pipeline; a return water outlet is connected with a water injection opening of the heat source well through a return water pipeline; a water outlet of the heat source well is connectedwith a water inlet of the heat source side circulating pump; heat exchange copper tubes are arranged in the condenser; end covers are arranged at two ends of the condenser; a high area heat supply outlet, a high area heat supply inlet, a low area heat supply outlet and a low area heat supply inlet are formed in each end cap; a separation baffle is arranged at each end cover of the condenser; the separation baffles divide a tube bundle formed by the heat exchange copper tubes into two independent water systems for high area heat supply and low area heat supply, and the independent water systemsare separately connected with the high area circulating pump and the low area circulating pump for supply heat for users of high area heating and users of low area heating.

Description

technical field [0001] The invention relates to the application field of new energy, in particular to a heating system and method for high and low zones using a ground source heat pump as a heat source. Background technique [0002] The gap in energy supply and the unreasonable energy consumption structure determine the importance and urgency of energy issues. For this reason, the central government promulgated and implemented the "Renewable Energy Law" in January 2006. Since then, water energy, wind energy, and biomass energy The application of recyclable clean energy such as solar energy, geothermal energy, etc. in the construction industry has increasingly attracted the attention of researchers. Among them, the use of ground source heat pumps for heating is a widely used renewable energy utilization method. [0003] When ground source heat pumps are used to provide heat sources for high-rise buildings, facing two independent water systems in the high and low areas of the...
