Embodiment Construction
[0020] The monitoring device of the ground source heat pump system based on the Internet of Things provided by the present invention includes: a soil temperature wireless sensor, which is used to obtain the soil temperature near a certain depth of the buried pipe, and the soil temperature at a certain distance from the buried pipe at the same depth. After monitoring this data for a quarter and a year, the thermal imbalance rate of the soil can be calculated. The outdoor air wireless sensor is used to obtain the real-time temperature of the outdoor air. Indoor temperature monitoring is used to ensure the quality of indoor air environment. The wireless temperature sensor, wireless flow sensor, and wireless smart meter at the inlet and outlet of the cold and heat source side and the air conditioning load side of the chiller are used to obtain the temperature and flow at the inlet and outlet of the cold and heat source side of the chiller and the air conditioner load side, and the...

The invention relates to the ground source heat pump technique and particularly relates to a device for monitoring the ground source heat pump system based on the internet of things. The device comprises a soil temperature wireless sensor, an outdoor air temperature wireless sensor, an indoor temperature wireless sensor, water inlet-outlet temperature wireless sensors arranged on a cold-hot resource side and an air conditioner loading side of a cold water machine set, a flow wireless sensor, a wireless intelligent ammeter, a wireless signal collecting module, a local server and a remote monitoring computer. The wireless signal collecting module collects the parameter of each sensor according to the ZigBee protocol, transmits the parameters to the local server by the Internet according to the Modbus protocol, and then stores, computes and displays the COP (coefficient of performance) and the WTF (water transport factor) curves by the ground source heat pump system, and finally transmits the parameters to the remote monitoring computer by the Internet. The device can obtain the CPI (comprehensive performance index), the COP (coefficient of performance) and the WTF (water transport factor) of the ground source heat pump, and is beneficial to monitoring the daily energy-saving situation of the ground source heat pump system and providing evaluation data for the energy-saving improvement of the system.
Description
technical field [0001] The invention belongs to the technical field of ground source heat pumps, and relates to a monitoring system, in particular to a ground source heat pump system monitoring device based on the Internet of Things, which can evaluate the performance of the ground source heat pump system. Background technique [0002] In recent years, ground source heat pump systems have become more and more widely used in most areas of our country, becoming one of the main forms of renewable energy building air conditioning applications in our country. Ground source heat pump system construction is a complex project with strong comprehensive technology, involving many disciplines such as architecture, hydrogeology, heat transfer, fluid mechanics, computer and automatic control. Due to the uneven level of design, construction and operation management at present, the actual performance of the ground source heat pump system is far from the design expectation. Seriously, the p...
