heat pump

1.solar + air source heat pump coupled heating technology

It consists of a flat solar evaporator, an air source heat pump, a buffer water tank, an intelligent controller, and a circulating pump.

During the day, the system uses a flat-panel solar evaporator to collect heat to improve the energy efficiency ratio of the compressor;

The system uses intelligent control to store heat in the buffer water tank and the indoor end while heating the building to achieve continuous heating;

At night, the valley electricity is used to heat the building.

Advantage:

• When there is sun, solar energy is mainly used, and air energy is used as compensation.
• When there is no sun, air energy is mainly used, and solar energy is used as compensation.
• More efficient and energy-saving than traditional air source heat pumps, the heating capacity is more than 30% higher.
• The equipment can be put into use on the same day of installation. Indoor one-button control panel, one-button power-on and one-button room temperature setting.
• Maximize the use of solar energy resources to meet the needs of users for daily building heating, and the indoor heating temperature is above 18°C. The system realizes intelligent remote operation and maintenance, and is unattended.

2. Air source heat pump fan + direct heating electric heater

The air source heat pump fan can form a combined heating system with direct heating electric heating equipment.

When the air source heat pump is heated by the air heater, the gas refrigerant (410A type -40 degrees) is compressed by the scroll compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (at this time as a condenser), and the heat released by condensing and liquefying becomes Liquid, while heating the indoor air, so as to achieve the purpose of increasing the indoor temperature.

The liquid refrigerant is decompressed by the expansion valve and enters the heat exchanger of the outdoor unit (at this time, it is used as an evaporator). It evaporates and absorbs heat to become a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder). The refrigerant that has become a gas enters the compressor again to start the next cycle.

The cooling and heating of the air source heat pump fan control the flow of refrigerant in the evaporator condenser through the four-way valve of the main engine. Through the liquefaction and vaporization process of the above refrigerant, the heat is absorbed at the evaporator and released at the condenser, so as to realize the transfer of heat and achieve the purpose of heating and cooling.

Advantage:

• The temperature of the air source heat pump fan is adjustable, and it is not affected by the environment. It can operate normally regardless of night, cloudy, rainy and snowy weather.
• There is no need to modify the indoor heat dissipation terminal, and it can be used with a variety of heat sources (electric heaters, water heating kangs, etc.), which can save 70% of energy compared with electric heating and 30% of energy compared with gas.
• Environmental protection and pollution-free, will not cause harm to the human body, and has good social benefits.
• The equipment occupies a small space, which is the best choice for heating in families, urban apartment buildings and residential buildings.
