Embodiment 1

[0040] Such as figure 1 , 2 As shown, a ground source heat pump underground heat exchanger heat transfer tester mainly includes a heat exchanger 9 buried underground, a water tank 1 and an instrument box 11 installed on the ground. The underground heat exchanger 9 is a U-shaped PE pipe, which is buried 100 meters underground. The water tank 1 is a square plastic container with a top cover. A water outlet is arranged on the upper part of the side of the water tank 1. The water outlet of the water tank 1 passes through the plastic outlet pipe 3 , and sequentially pass through the spherical control valve 5, the temperature sensor 6, the circulating water pump 8, the flow sensor 7 and the pressure gauge 15, and one end of the underground U-shaped PE pipe heat exchanger 9 is screwed together. A water inlet is provided on the lower part of the other side of the water tank 1. The water inlet of the water tank 1 passes through the plastic water inlet pipe 4, and then passes through t...

Embodiment 2

[0042] A heat transfer tester for an underground heat exchanger of a ground source heat pump, the same as in Example 1, characterized in that the underground heat exchanger 9 is a U-shaped aluminum-plastic composite pipe, buried 50 meters underground, and the water tank 1 has a roof Covered rectangular iron container, the outlet of the water tank 1 passes through the galvanized steel pipe outlet pipe 3, and then passes through the spherical control valve 5, the temperature sensor 6, the circulating water pump 8, the flow sensor 7 and the pressure gauge 15, and the underground U-shaped aluminum plastic One end of the composite pipe heat exchanger 9 is screwed, the water inlet of the water tank 1 passes through the galvanized steel pipe inlet pipe 4, and then passes through the spherical control valve 5, the temperature sensor 6 and the pressure gauge 15, and connects with the underground U-shaped aluminum-plastic composite pipe. The other end of the heat exchanger 9 is screwed, ...

Abstract

A heat exchange measuring device of the ground source heat pump underground heat interchanger relates to the scene measuring device of the ground source heat pump underground heat interchanger. The invention includes a heat interchanger buried under the ground and a water tank having a heater and a refrigerator arranged above the ground and a meter box having five figure display instruments. The invention has simple structure, convenient operation, exact measurement and high precision, which can measure the heat dissipating capacity and the decalescence heat exchange of the ground source heat pump underground heat interchanger, and can adjust the parameters of the burying depth of the underground heat interchanger, the water intake flux of the burying device, the water intake temperature for measurement. The invention can be widely used for the measurement of the heat dissipating capacity or the decalescence heat exchange basic data, which provides reliable, comprehensive and correct basis data to the design, the construction and the operation of the ground source heat pump system engineering.

Description

1. Technical field: [0001] The invention belongs to the technical field of testing ground source heat pump systems, and in particular relates to a field test device for exchanging heat of underground heat exchangers of ground source heat pumps. 2. Background technology: [0002] According to incomplete statistics, my country's building energy consumption has reached 27.5% of the total energy consumption at present, and this figure will continue to increase with the rapid development of my country's construction industry. Therefore, with the establishment of the basic national policy of energy conservation and emission reduction, the development of building energy conservation work is even more significant. According to the country's goal of achieving 65% energy saving in buildings, in addition to improving building enclosures to achieve energy savings of 30% to 35%, energy-consuming equipment and systems must also achieve energy savings of more than 30%. The use of renewabl...
