Product Description
Introduction of small ground source heat pump unit

The small-scale ground source heat pump unit is a mature shaped product developed on the basis of fully absorbing the latest development technology in the international and domestic air-conditioning field.The unit is designed and manufactured strictly in accordance with national industry standards,and selected high-quality,famous brand compressors,water pumps,refrigerant system control components and computer control components produced by world-renowned manufacturers.The operation has nothing to do with the ambient temperature,so that the unit can operate efficiently and stably anywhere.

Small ground source heat pump units usually have no heating boiler,no heating network or other stable and reliable heat source,but they also require the preferred option in the heating engineering design of air conditioning throughout the year.This unit can form a semi-centralized air conditioning system together with fan coil or cabinet type,ceiling type air handler and new fan unit.     

There are various forms of heat sources for small ground source heat pump units.When designing the unit,consider different operating conditions,conduct comprehensive design,and reasonably match,so that the unit can operate stably and efficiently under different operating conditions,and meet the requirements of different projects to the greatest extent.


Application
  The unit is widely used in hotels,shopping malls,office buildings,villas and other small and medium-sized places for comfortable central air-conditioning systems.Pharmaceutical,biological,and other smaller places require a higher level of process air conditioning systems.

Features

1. Wide selection

(1)The single unit cooling capacity of this series is from 15kW to 75kW,and the cooling capacity is tightly and evenly distributed.The user can tailor it,and the cooling capacity is wide;

(2)The water temperature on the heat source side of this series of units is-10℃~35℃,and the water temperature on the use side is-5℃~50℃,which can run stably and efficiently,and the unit operates in a wide range;

(3)This series of units integrate refrigeration,heating and sanitary hot water into one,which can cool,heat and supply domestic hot water.The unit has a wide range of application functions;

(4)This series of units have R22,R407C refrigerant to provide options

2.  Advanced technology

This series of units use a variety of advanced air-conditioning technologies,such as multi-energy level regulation;unique heat pump built-in heat recovery technology;efficient and accurate unit waterside antifreeze……

3.  Smooth running,quiet and low noise

The unit adopts high-efficiency fully-enclosed scroll compressor, horizontal multi-stage centrifugal pump, fully enclosed structural shell, low noise and stable operation.

4.  Excellent heat source,stable operation

As a low-temperature heat source,the water temperature is relatively stable all the year round,and its fluctuation range is far less than the fluctuation of air temperature,which makes the operation of the unit more stable and reliable,and also ensures the efficiency and economy of the system.There is no such difficult problems as defrosting in winter and heat reduction of the air source heat pump unit.

5. Digital centralized control,accurate and efficient

The compressor,water pump,refrigeration system accessories and electric control components used in the unit are all products of famous companies at home and abroad,with accurate control and reliable performance.The operation interface of the controller is friendly,and the user can know the operation of the unit at any time.With high automation and complete functions,the unit can realize the functions of start and stop program management,timing control,fault alarm and fault self diagnosis.At the same time,it can be equipped with RS485/RS232 communication interface(optional),which is convenient for users to realize the centralized monitoring and remote monitoring of the unit.

6. Complete protection,safe and reliable

The unit is equipped with high-pressure,low-pressure switch,overload relay,phase sequence protector,antifreeze protection,delay start and other protection devices to ensure the safe and reliable operation of the main engine.

7. Simple installation and complete functions

The internal reversing of the refrigeration system and the external refrigerant system do not need the change-over valve of cooling and heating,which makes the installation of the whole air conditioning system simple and clean,as the operation of home air conditioning is convenient. The unit can be installed and fixed only by making simple cement foundation.

8. Clean and environmental protection,high efficiency and energy saving

This series of units take water as the cold and heat source,the operation efficiency is higher than that of air source heat pump units, cop is above 5.4, and it is awarded the title of"energy saving star".During cooling,the cooling tower is omitted to avoid noise and mound pollution of the cooling tower;during heating,there is no combustion process,no waste residue, waste water,exhaust gas and smoke exhaust,and coal,oil,gas boilers and boiler rooms are omitted to make the environment more beautiful.
