Empowering a Green Future With Technology
Core Principles and Cycles
Heat pumps rely on four major components to complete a closed cycle, achieving the "transfer" of heat rather than "manufacturing":
Evaporator
Liquid refrigerant absorbs heat and evaporates into a gaseous state, taking heat from a low-temperature heat source (such as outdoor air).
Compressor
compresses gaseous refrigerant to rapidly increase its temperature and pressure.
Condenser
The high-temperature and high-pressure gaseous refrigerant releases heat and condenses into liquid form, releasing heat to the high-temperature end (such as indoors or in a water tank).
Expansion valve/throttling component
The liquid refrigerant is depressurized and cooled, and flows back to the evaporator to enter the next cycle.
What is an air source heat pump?
An air source heat pump (ASHP) is an efficient energy-saving device that uses outdoor air as a low-temperature heat source, drives a compressor through a reverse Carnot cycle, and consumes a small amount of electrical energy to "transfer" low-grade air heat energy to indoor or water tanks. The core is "heat transfer" rather than "manufacturing", and the COP under standard operating conditions is usually around 5, which is 80% more energy-efficient than electric heating. It can provide heating, cooling, or hot water supply.
The principle of heat pump
The core principle of a heat pump is the "reverse Carnot cycle" - by consuming a small amount of high-grade energy to drive the compressor to do work, heat is "transported" from low-temperature heat sources (such as air, water, soil) to high-temperature heat sources (such as indoor and water tanks), achieving the "upgrading and utilization" of heat, rather than directly "producing" heat (different from the energy conversion of electric heaters).

Refrigerant
R290 and R32 are both environmentally friendly natural refrigerants in the industry, suitable for environmental protection, energy efficiency, and safety. R290 is extremely environmentally friendly, with outstanding low-temperature heating efficiency.
Safety protection
The multi-layer safety protection technology in the air source to water heat pump system includes multiple functions, such as refrigerant leak detectors, advanced antifreeze logic, and refrigerant/water separation devices. These features ensure the safety of customers. And by preventing overheating, reducing electrical faults, monitoring temperature for anti freezing protection, and preventing refrigerant water pollution, the reliable operation of the system is ensured.
What is PV direct driven technology?
PV direct drive technology couples solar panels directly with heat pumps, allowing compressors and fans to operate directly using solar DC power without the need to first convert DC to AC through grid connected inverters. By eliminating this conversion step, the system shortens the energy path, reduces conversion losses, and simplifies the system's balancing components. The result is higher overall efficiency, faster response to changes in solar energy conditions, while still providing reliable heating, cooling, and domestic hot water (DHW). Unlike traditional photovoltaic+inverter+AC heat pump combinations, photovoltaic direct drive heat pumps integrate maximum power point tracking (MPPT) technology, allowing the photovoltaic array to always operate at the optimal voltage/current state, maximizing solar energy utilization around the clock. In practical applications, the system can independently form a solar optimized configuration, as well as form a hybrid mode with the power grid or battery to ensure a comfortable environment during rainy weather and nighttime.
What is the MPPT function?
MPPT is a control method that continuously adjusts the voltage and current of a photovoltaic array, ensuring that the solar panel operates at its maximum power point under changing sunlight and temperature conditions. The controller does not maintain a fixed set value, but constantly "searches" for the optimal operating point for the maximum output power of the array - releasing higher solar energy collection efficiency from the same solar panel. After adopting MPPT technology, the system can provide stable and optimized DC power supply for the compressor and fan, smooth out power fluctuations when clouds pass by, and maintain high-performance operation around the clock. The result is an increase in self consumption rate, a reduction in conversion losses, and an improvement in actual efficiency - ultimately achieving lower energy bills, more stable comfort, and avoiding equipment wear and tear due to unnecessary start stop cycles.
