Description

Technical Field

[0001] The utility model relates to the technical field of ground source heat pump units, in particular to a ground source heat pump unit. Background Art

[0002] A ground source heat pump unit is a device that uses water circulating in public pipelines, water drawn from wells, lakes or rivers, or water circulating in underground coils as a cold (hot) source to produce cold (hot) air or cold (hot) water.

[0003] When the existing ground source heat pump unit is working, the internal components will generate heat. In order not to affect the operation of the ground source heat pump unit, it is necessary to dissipate heat in time. Ventilation and heat dissipation are mostly carried out through fans, so that the outside air can enter the interior and take away the heat. However, dust and moisture are also brought in at the same time. Long-term use causes dust and moisture to accumulate inside and cover the surface of the equipment, increasing the load of the internal components during operation, increasing the resistance, and thus affecting the service life. At the same time, when the temperature is low in winter, the surface temperature of the ground source heat pump unit is low, which will cause the ground source heat pump unit to be frozen or affect its normal operation. During the use of the ground source heat pump unit, the surface of the condenser or evaporator will dissipate more heat, resulting in low energy utilization. Utility Model Content

[0017] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] A ground source heat pump unit, combined with Figure 1 to Figure 2 As shown, it includes a chassis 2 and a ground source heat pump unit body 1 , and the ground source heat pump unit body 1 is arranged in the chassis 2 .

[0019] The upper part of the left side box plate of the chassis 2 is connected with a wind tube 3, which is arranged horizontally. A fan 4 and a dehumidification component are arranged in the wind tube 3, wherein the fan 4 is used to blow air into the chassis 2, thereby dissipating the heat of the ground source heat pump unit body 1 in the chassis 2; the dehumidification component is located on the side of the blowing port of the fan 4, and the dehumidification component is used to dehumidify the incoming air, thereby preventing the incoming air from containing moisture and affecting the service life of the ground source heat pump unit body 1. An air outlet 11 is provided at the bottom of the right side box plate of the chassis 2, and the air outlet 11 is arranged obliquely and misaligned with the wind tube 3, thereby facilitating the overall ventilation and heat dissipation in the chassis 2; at the same time, the air outlet 11 is opened obliquely outward and downward, thereby preventing external dust from entering the chassis 2 through the air outlet 11.

When the temperature is low in winter, the electric heating tubes 9 and the fan 4 are turned on first, and the electric heating tubes 9 heat the incoming air, so that the heated incoming air quickly exchanges heat with the ground source heat pump unit body 1 and drives out the cold air in the chassis 2, thereby quickly heating the surface of the ground source heat pump unit body 1, and then the fan 4 is turned off, and the electric heating tubes 9 continue to work to achieve heating of the space in the chassis 2 and maintain a constant temperature, thereby preventing the ground source heat pump unit body 1 from being frozen, ensuring the normal operation of the ground source heat pump unit body 1, and avoiding the situation where the condenser or evaporator surface dissipates a lot of heat during the use of the ground source heat pump unit body 1, resulting in a low energy utilization rate.

[0025] When the utility model is in use, the fan 4, dehumidification assembly and electrostatic adsorption plate are arranged, which can not only ventilate and dissipate heat for the ground source heat pump unit body 1, but also avoid the introduction of moisture and dust, thereby increasing the service life of the ground source heat pump unit body 1; the electric heating pipe 9 is arranged, and the surface temperature of the ground source heat pump unit body 1 can be guaranteed when the temperature is low in winter, thereby avoiding the ground source heat pump unit from being frozen or affecting its normal operation, so that the condenser or evaporator surface will not dissipate too much heat during the use of the ground source heat pump unit body 1, thereby ensuring energy utilization.
