HZS series water ground source heat pump unit

HZS series water ground source heat pump unitIt is a new type of heat pump technology that utilizes the energy of shallow ambient temperature groundwater as an energy source. This technology can provide both heating and cooling simultaneously, and can provide hot water for daily life. It uses water and ground energy (groundwater, soil, or surface water) to exchange heat and cold as the heat source of a water source heat pump. In winter, the heat in the ground energy is "extracted" and supplied to indoor heating. At this time, the ground energy is the "heat source". In summer, the indoor heat is extracted and released into groundwater, soil, or surface water, and the ground energy is the "cold source"

Source. It does not emit any exhaust gas, wastewater, or debris to the outside world, making it an ideal 'green technology'. From the perspective of energy efficiency, it is an inexhaustible renewable energy source.

HZS series water ground source heat pump unitIt has the characteristics of high energy efficiency ratio, compact structure, beautiful appearance, easy operation, and simple refrigeration system process. The refrigeration and heating process is achieved through the switching of water system pipelines. At present, water source heat pump units have been widely used in shopping malls, hotels, guesthouses, hospitals, factories, office buildings, northern centralized heating, industrial heat recovery and other occasions.

The Haizhizhou screw water source heat pump unit mainly has the following characteristics:

1. The condenser and dry evaporator of the unit are compact in structure and operate smoothly. Both use heat transfer tubes, and the main engine adopts a semi closed twin-screw compressor, which has many advantages such as compact structure, small volume, light weight, and small installation position. The semi enclosed twin-screw compressor has fewer moving parts and uses a 5:6 super screw rotor. There is no direct wear between the rotors, making it highly reliable. Due to the fact that screw machines are continuous compressors without pulsation, water (ground) source heat pump chillers have the characteristics of stable performance, low noise, small vibration, and smooth operation. Improved efficiency by 20% -30% compared to reciprocating compressors, and has obtained IS09001 quality certification and multiple European and American countries;

2. Easy and intuitive operation

The unit adopts a microcomputer programmable logic controller (PLC display in Chinese or English), with a touch screen display. Select the operation according to the menu on the screen, and directly touch the display button on the screen with your finger to start the water (ground) source heat pump chiller unit. The screen can display the operating status of the water source heat pump unit at any time, and can display the parameters in two ways: graphics and text tables, making it clear at a glance;

3. Independent refrigeration cycle system

A large capacity has two or more independent refrigeration circuits, so that even if one circuit fails/needs maintenance, the other circuit can still operate normally. Equipped with mutual backup function, especially suitable for use in air conditioning and industrial non-stop environments;

4. A comprehensive energy control system

The unit has a four level capacity control system, with energy regulation of [100, 75, 50, 25 (or start, 0%)], which automatically adjusts the start and stop of the unit according to load changes, making it more energy-efficient;

5. Protection function of microcomputer controller

It has protection functions such as compressor coil temperature high protection, oil preheating timed power on/off, cold water flow switch, cold water outlet temperature low protection, Y - △ start failure protection, exhaust temperature high protection, compressor overload protection, power-off memory function, frequent start stop protection, voltage abnormality protection, low oil level protection, high and low voltage protection, etc;

6. High degree of automation control:

Fully functional and capable of achievingHZS series water ground source heat pump unitStart stop program management, timed control, water pump management, full function fault alarm, and fault self diagnosis function. Simultaneously equipped with RS485 communication interface, convenient for users to achieve centralized and remote monitoring of the unit;

7. Significant environmental benefits:

It is a heating and air conditioning system that utilizes surface water as a cold and heat source for energy conversion. Heating eliminates the need for boiler room systems such as coal, gas, and oil, eliminating the combustion process and avoiding pollution such as exhaust and discharge; When providing cooling, the cooling tower is omitted, avoiding the noise, mold pollution, and water consumption of the cooling tower;

8. Energy conservation and environmental protection

The electricity used is a clean energy source, and a well-designed water source heat pump unit can reduce electricity consumption by more than 30% compared to air source heat pumps, and by more than 70% compared to electric heating. Therefore, water source heat pumps not only save energy but also reduce and minimize the pollution emissions and greenhouse effect generated during the primary energy consumption process during power generation;

9. Easy to install

allHZS series water ground source heat pump unitAll components have been installed and tested in the factory, and refrigerant and refrigeration oil have been added. Users only need to connect the water and circuit to put them into use, reducing installation and debugging time;
