Abstract

The invention relates to a geothermal direct-connect heat supply unit. A water pump is arranged on a pedestal. A water inlet pipe is arranged in front of the water pump and connected with a low-temperature heating backwater main pipe of a pipe network. A water outlet pipe is arranged in the back of the water pump and connected with a lateral water-mixing elbow pipe of a water mixer. A main water inlet pipe of the water mixer is connected with a high-temperature heating water supply main pipe of the pipe network. A water outlet pipe of the water mixer is connected with a geothermal heating water supply main pipe. A temperature controller is arranged on the main water inlet pipe of the water mixer. A temperature sensor is arranged on the water outlet pipe of the water mixer. The signal input end of a frequency-variable control cabinet is connected with the temperature sensor. The output end of the frequency-variable control cabinet is connected with the control ends of the water pump and the temperature controller respectively. The geothermal direct-connection heat supply unit has the advantages of low cost, easy construction, small size, low running costs, environmental friendliness, easy management, high safety and reliability, convenient maintenance and easy promotion, and can prepare the hot water required for geothermal heating.

Description

technical field [0001] The invention relates to a geothermal direct connection heating unit, which makes it possible for a geothermal heating system to be directly connected without a heat exchanger to prepare hot water suitable for geothermal heating. Background technique [0002] Due to the increasing number of residential buildings in various places, the number of buildings using geothermal heating is also increasing. The heating pipe network in cities all over the country generally determines the heat medium parameters according to the radiator heating system of multi-storey buildings. Plastic pipes, and the water supply temperature of the urban heating pipe network is generally 80 / 55°C, which cannot be directly used for geothermal heating. Heat exchangers must be used to prepare 60 / 50°C hot water suitable for geothermal heating parameters, which will increase The investment increases operating costs and also increases energy consumption.
