Features and uses

The ground temperature water source heat pump central air-conditioning device uses the heat pump working principle of the refrigeration compressor to produce cold water or hot water for end-user air conditioning. The ground temperature (15℃) water source is used as the cold source (when cooling) or the heat source (when heating) of the unit, which can reduce the working temperature difference of the heat pump, and greatly improve the cooling coefficient or heating coefficient of the unit, so that the energy saving effect is remarkable. Other water sources with a temperature higher than 8°C can also be used as the water sources for the central air-conditioning device, such as river water and cooling water for machines. In summer (cooling condition), the lower the water source temperature, the greater the cooling coefficient, and the greater the cooling capacity of the unit; in winter (heating condition), the higher the water source temperature, the greater the heating coefficient, and the greater the unit’s heating capacity. Thus, the energy saving effect can be increased.

The ground temperature water source heat pump central air-conditioning unit has a special type for residential bungalows (SRB8), a special type for villas (SRB13.2~SRB22) and a business type (SRB26~SRB100). The business-type geothermal water heat source pump central air-conditioning unit heats hot water for bathing, which is safe, economical and hygienic.

Composition and working principle

Ground temperature water source heat pump cold and hot water unit (including circulating water pump, expansion tank, etc.) - as the central unit of the ground temperature water source heat pump central air conditioning unit, it is installed in the central air conditioner room to provide cold water (summer) and hot water (winter) for the air conditioning system .

Well Pump - Submersible pump (installed in a well).

Fan coil unit - used for room air conditioning, installed in the user's room. Types are: vertical cabinet type, wall-mounted type, ceiling type, horizontal type, vertical type, etc.

Well water pipeline, air conditioning circulating water pipeline.

Monitoring system - mainly includes automatic monitoring system for ground temperature water source heat pump chiller and hot water unit and room monitoring system.
