Efficient indoor heating system for capillary pump

Abstract

The invention discloses an efficient indoor heating system for a capillary pump. The efficient indoor heating system for the capillary pump comprises a secondary network indoor water supply transversepipe, a secondary network indoor return water transverse pipe, an evaporator, a steam conveying pipeline, a gas-liquid isolator, a liquid conveying pipeline, a pressure sensor, a pressure regulatingstorage device, an electric heating device, a programmable controller, an outdoor temperature sensor and a condenser. The evaporator is provided with a heating medium inflow port and a heating mediumoutflow port, and a plurality of capillary liquid absorbing cores are arranged in the evaporator in parallel. The system can significantly reduce the return water temperature of a secondary network, thereby increasing the supply and return water temperature difference of the secondary network and reducing the circulation pump flow and electric energy consumption of the secondary network; and meanwhile, the primary network return water temperature is reduced, the supply and return water temperature difference of a primary network is increased, the circulation pump flow rate and electric energyconsumption of the primary network are reduced, and energy-saving operation of a transportation and distribution system is realized.

Description

technical field [0001] The invention relates to a building heating system, in particular to a capillary pump high-efficiency indoor heating system. Background technique [0002] According to the national standard GB50736-2012 "Code for Design of Heating, Ventilation and Air Conditioning in Civil Buildings", the design supply and return water temperature of the indoor heating system: geothermal coil system 60 / 50 ℃, radiator system 85 / 60 ℃. Assuming that the "minimum heat transfer temperature difference" of the heat station plate heat exchanger is 10°C, then under the design conditions, the return water temperature of the primary network will not be lower than 60°C, and a large number of low-grade waste heat resources (condensation heat of thermal power plants, About 29 ℃; various industrial waste heat, 15 ~ 50 ℃) cannot be directly and efficiently utilized, but need to use heat pump equipment. [0003] Compared with the primary network, the design temperature difference betw...

Problems solved by technology

The uniformity of the surface temperature of the end of the conventional heat dissipation is poor. For the geothermal coil, the temperature of the heat medium flowing to the end of the coil is relatively low, which may cause uneven heating and cooling in the room.
