How Do Inverter Heat Pumps Work?

There is a clear difference between inverter heat pumps and non inverter heat pumps. Inverter heat pumps are suitable for residential or workplace use, while inverters are electronic devices that convert direct current into alternating current. Direct current (DC) refers to the current in which charges flow in one direction or in one direction, while alternating current (AC) is a current that repeatedly reverses direction. For inverter heat pumps, their voltage, output voltage, power, and frequency depend on their design. They cannot generate power on their own and require a DC power source to provide sufficient stable current.

So, how does a inverter heat pump work? The variable frequency heat pump adopts energy-saving technology, which can eliminate performance waste in air conditioning and achieve energy-saving heating and cooling by controlling the motor speed. Variable frequency heat pumps can provide comfortable temperatures, economically maintain temperature stability, and are suitable for saving energy costs, keeping warm while saving energy.

What is a Inverter heat pump

Cold weather Inverter heat pump is a type of heat pump that uses advanced energy-saving technology, which can effectively eliminate energy waste in air conditioning. For consumers who want to reduce energy consumption, Inverter air source heat pumps are particularly important. It achieves energy-saving heating and cooling by precisely controlling the motor speed, thereby maintaining stable indoor temperature.

How does a Inverter heat pump operate?

It can provide comfortable temperature and economically maintain stable indoor temperature. The inverter air to water heat pump can perform small-scale temperature regulation, which is suitable for saving expensive energy costs in homes or workplaces, and keeping warm in cold winters and cool in hot summers. There are two types of variable frequency heat pumps, namely pipeline type and non pipeline type.

The pipeline variable frequency heat pump operates at 100% volume and can operate when the outdoor temperature is low. It also has a variable frequency compressor that can effectively control the energy of the system. Research has shown that pipeline variable frequency heat pumps can reduce energy consumption by 35% and are equipped with compressor silencers, making the machine quieter.

The ductless variable frequency heat pump is known for its small split system, which allows customers to control the temperature of rooms or spaces. It includes an outdoor compressor and an indoor condenser, connected through pipelines to transport refrigerant between units in a small split system.

What is the working principle of a inverter heat pump?

It has multiple operating modes and uses a high-speed compressor (also known as a rotary compressor) that operates all day. When using a speed compressor with a reverse heat pump, it adjusts the speed based on external temperature changes to match the heat inside the building. By taking heat away from the outdoor air, variable frequency heat pumps can provide heating for buildings in winter and remove heat from the building in summer, thereby cooling the air.

In the refrigerant circulation process of variable frequency heat pumps, the cycle operates at different speeds and is adjusted according to temperature and heat requirements to reduce energy consumption. The variable frequency air water heat pump rotary compressor and fan motor can operate in the range of 0 to 100%, while the inverter heat pump uses a DC power source, converts AC power into DC power through a rectifier, and adjusts the speed of the motor by changing the frequency, achieving speed adjustment from small to fast.

Inverter heat pump VS non inverter heat pump

There is a significant difference between non inverter (also known as on/off) heat pumps and inverter driven heat pumps. Unlike Inverter heat pumps, non Inverter driven heat pumps cannot control the energy output. Therefore, the motor running on a non variable frequency heat pump operates in two modes of motion. The two actions for turning on/off the heat pump are full speed and stop. During normal use, the motor in the on/off heat pump will run full-time. When the temperature inside the building or room reaches a specific and expected level, the motor stops. Due to the motor in a non variable frequency heat pump repeatedly starting and stopping throughout the day, it utilizes more energy.

The DC inverter heat pump uses a rectifier to convert AC power into DC power, and then converts the DC power into variable frequency and voltage. Most variable frequency heat pumps are equipped with EVI compressors, which represent enhanced steam injection and can expand the range of heating cycles, especially suitable for low outdoor temperatures. In addition, the variable frequency heat pump also uses EEV, which is an electronic expansion valve located inside the variable frequency heat pump and controls the refrigerant flow into the evaporator. By precisely adjusting fluid pressure, electronic expansion valves help achieve refrigerant evaporation.

When the refrigerant turns into a gas, it will cool down. However, electronic expansion valves can sometimes cause excessive refrigerant movement. This may cause overheating. To calculate how much overheating has occurred, you can subtract the temperature on the suction side of the compressor from the evaporation temperature of the reverse heat pump. There are sensors on the electronic expansion valve and evaporator outlet to measure the degree of overheating.

The electronic expansion valve has some key components, such as permanent magnets and copper coils inside the stepper motor. The motor located at the top of the valve generates an electromagnetic field. The field moves the threaded shaft connected to the motor. Then, the shaft will push an appropriate amount into the valve seat inside the valve. The technology used in electronic expansion valves comes from countries such as Europe.
