Product Introduction
Domestic hot water heat exchange units are integrated heat exchange devices specifically designed to meet the domestic hot water needs of various locations.It uses high-efficiency heat exchangers (mostly plate or shell-and-tube type) as the core, and is equipped with components such as circulating pumps, temperature control valves, filters, and intelligent control cabinets.It transfers heat from centralized heating networks, boilers, heat pumps, and other heat sources to cold water in domestic water pipes, quickly heating the cold water to a temperature that meets domestic use standards (usually 35-55℃).It achieves fully automated operation, providing users with a stable, safe, and energy-efficient supply of domestic hot water, and is the core equipment of domestic hot water systems in hotels, residences, hospitals, and other places.
Product Features
1.Highly efficient heat exchange and rapid heating:It employs heat exchange elements with high thermal conductivity (such as 304 stainless steel plate heat exchangers), resulting in a large contact area between hot and cold media and high heat transfer efficiency.It can heat cold water to the set temperature in a short time, meeting the demand for rapid hot water supply during peak hours, with a thermal efficiency of over 90%.
2.Precise temperature control, stable water temperature;Equipped with a high-precision temperature sensor and intelligent temperature control system, it monitors the hot water outlet temperature in real time and automatically adjusts the flow rate of the heat source medium to ensure that the water temperature fluctuation is controlled within ±1℃, avoiding sudden changes in hot water temperature and improving user comfort.
3.Comprehensive security protection:It is equipped with multiple safety protection devices, including over-temperature protection (automatically cuts off the heat source when the water temperature is too high), over-pressure protection (triggers the safety valve to release pressure when the system pressure is abnormal), and leakage protection (automatically cuts off the power when electrical components leak current).It also incorporates an anti-scaling design to reduce the impact of scale buildup on the equipment and ensure safe operation.
4.Significant energy conservation and emission reduction:Supports waste heat recovery (such as recovering waste heat from bathing wastewater) to reduce heat source consumption; some models are equipped with variable frequency circulating pumps.The pump speed can be automatically adjusted according to the amount of hot water used, reducing unnecessary energy consumption. Compared with traditional hot water heating equipment, the energy saving rate can reach 15%-30%.
5.Easy to install and compact:Adopting a modular integrated design, all components are pre-installed on a unified base, and only the inlet and outlet water pipes and power supply need to be connected on site for it to be put into use.No complex assembly required; the equipment is compact, occupying only 1/2 to 1/3 of the space of a traditional decentralized hot water system, making it suitable for small equipment rooms or basement spaces.
6.Simple maintenance and long lifespan:The heat exchanger adopts a detachable structure (such as a plate heat exchanger with removable and washable plates), which facilitates regular cleaning of scale and impurities.The core components are made of corrosion-resistant materials (304 stainless steel, copper alloy, etc.), which have strong corrosion resistance and aging resistance. Under normal maintenance, the equipment can last for 8-12 years.
Product Functions
Core Heating Function
Heat is transferred from a heat source (such as high-temperature hot water or steam) to cold water through a heat exchanger, thus achieving rapid heating of the cold water.We continuously provide users with domestic hot water that meets the required temperature, satisfying their daily needs such as washing, bathing, and cleaning.
Constant temperature supply function:
When hot water usage decreases or stops, the system automatically activates the circulation and heat preservation mode, using a circulation pump to continuously circulate the hot water in the pipes.Maintaining a stable water temperature within the pipes prevents cold water from being released during the next use, thus achieving "instant hot water".
Intelligent start/stop and adjustment:
Equipped with a PLC intelligent control system, the equipment can automatically start and stop according to preset usage periods (such as peak water usage times in the morning and evening for residential buildings).At the same time, it can dynamically adjust the heat source input and circulation pump speed according to the real-time hot water consumption to match the actual needs and reduce energy waste.
Water filtration and purification:
Built-in precision filter (filtration accuracy ≥40μm) can intercept impurities such as silt, rust, and particulate matter in the water.Prevent impurities from clogging the heat exchanger channels and hot water pipes, ensuring clean hot water quality and extending the service life of equipment and pipes.
Fault diagnosis and alarm:
The intelligent control cabinet monitors equipment operating parameters (water temperature, pressure, current, flow rate) in real time. When problems such as over-temperature, over-pressure, or pump failure occur, the system automatically issues an audible and visual alarm, displays the cause of the fault on the screen, and records the fault information to facilitate quick troubleshooting and repair by maintenance personnel.
Remote monitoring and management:
Some models support IoT access, allowing users to view the device's operating status, hot water supply, and energy consumption data in real time via a mobile app or computer backend.It can also remotely set the water temperature and adjust the operating mode to achieve unattended intelligent management.
Scope of Application
Residential properties
Suitable for high-rise residential communities, villa complexes, apartment buildings, etc., it provides residents with domestic hot water for washing, bathing, and kitchen cleaning, and can meet the centralized hot water supply needs of hundreds to thousands of households.
Hotels and restaurants
This includes star-rated hotels, budget hotels, guesthouses, restaurants, and eateries, all requiring a stable 24-hour hot water supply for guest rooms and restaurant patrons.It is suitable for high-flow, high-frequency hot water usage scenarios, ensuring a sufficient supply of hot water during peak hours (such as morning and evening washing peaks).
Medical and elderly care facilities
These include general hospitals, specialized hospitals, nursing homes, and care facilities, all of which must provide hot water that meets hygiene standards (stable water temperature and clean water quality).For applications such as patient care, cleaning for medical staff, and bathing for the elderly, the safety and stability of the equipment must meet medical-grade requirements.
Public and commercial spaces
Suitable for multi-user, decentralized hot water usage scenarios such as schools (primary and secondary schools, university dormitories and canteens), office buildings (staff restrooms and tea rooms), gyms (shower rooms), swimming pools (shower and cleaning water), and shopping malls (public restroom hot water supply).
Leisure and service venues
This includes establishments such as hot spring resorts, water parks (for showers), beauty salons, and foot massage parlors, all requiring a continuous supply of hot water at a suitable temperature. Some scenarios also need to incorporate waste heat recovery systems to reduce operating costs.
Industrial and special locations
Suitable for centralized hot water supply in factory employee dormitories and temporary living areas of construction sites; it can also be used in food processing plants (cleaning hot water that meets food-grade hygiene standards), kindergartens (safe and anti-scalding hot water supply), and other scenarios with specific requirements for hot water.
