The air source heat pump system extracts the low-temperature heat energy in the air, and uses the compression of the compressor to convert the low-temperature heat energy into a high-temperature heat source, so as to realize heating and hot water supply. The whole process does not involve any pollutant emission.

Air-cooled direct-cooled high-efficiency powder air cooler is easy to install, simple, fast, and the use effect is efficient and stable. The refrigeration compressor adopts foreign first-line brands, and the fully enclosed compressor has low noise and high efficiency. Unit with efficient heat exchanger, unit durable, stable operation, high efficiency and energy saving. Using single-chip microcomputer control, the control temperature is very accurate, can provide 5-20 ℃ adjustable air temperature. The unit has its own protection function, high and low voltage protection, power phase sequence protection, overload protection, to ensure the stable operation of the equipment.

The special unit for environmental control in the greenhouse has changed the history of "relying on the sky" planting. By using special refrigeration equipment to force refrigeration, the vegetables and fruits in the greenhouse enter the dormant state 10-20 days earlier than the vegetables and fruits in the regular greenhouse. By artificially adjusting the microclimate environment in the greenhouse and simulating the winter meteorological climate, the refrigeration, heating, humidification and dehumidification requirements of the dormant period, growth period, pollination period and picking period of cherries produced out of season can be met, so that the vegetables and fruits in the greenhouse can sprout, blossom and bear fruit in advance and go to the market in advance, thus changing the current situation of no domestic high quality and vegetables and fruits sold before and after the Spring Festival.

The integrated hot water module independently developed by our company adopts Copeland ZW series jet enthalpy increasing compressor, Japan Heron Palace four-way valve and electronic expansion valve, and France Schneider contactor. The unit can operate normally and efficiently at -35 ℃ ambient temperature to produce hot water, and the outlet water temperature is 40 ℃-60 ℃. The module integrates low temperature air source heat pump unit, heat preservation water tank, water pump, silicon phosphorus crystal tank and automatic water replenishment device, which has the advantages of convenient installation and low maintenance cost compared with traditional hot water system.

The low-temperature air-cooled cabinet machine independently developed by the company adopts Copeland ZW series jet compressor, Japan Palace four-way valve and electronic expansion valve, and France Schneider contactor. The unit can operate normally and efficiently at an ambient temperature of -35 ℃ for heating. Compared with traditional water machines, it has the advantages of convenient installation, low maintenance cost, high air outlet temperature, strong frost resistance, etc.

High-efficiency air supplement and enthalpy compressor, intelligent control system, precise flow control

Water ground source heat pump includes 5 series of small water ground source heat pump, modular water ground source heat pump, dry screw water ground source heat pump, flooded water ground source heat pump and falling film water ground source heat pump, with more than 100 specifications and models, which can be applied to special fields such as sewage heat recovery, bath heat recovery, waste heat recovery, etc.

The special hydraulic module for heat pump is a complete water treatment system unit that integrates almost all components related to the hydraulic system, such as water pump, valve, filter, constant pressure water supply device, water pump, electric control cabinet, etc. in a box.

Two-stage coupling heat pump heating system is a set of integrated heating system formed by organically coupling low-temperature air source heat pump and water source heat pump through buffer water tank. Its full name is "distributed air source-water source coupling heat pump heating system (hereinafter referred to as two-stage coupling heat pump heating system). This system is a new generation of HVAC system developed to solve the problem that single low-temperature air source heat pump cannot realize high-temperature heating in severe/cold areas.
