Dual Air Water Source Geothermal Heat Pump Unit

PRODUCT DETAIL

Dual air water source geothermal heat pump unit

1）Product description

Dual source heat pump adopts efficient fin-type evaporator, evaporative condenser and shell-and-tube heat exchanger (cooling and heating mode). With all those parts, unit combines the functions of evaporative cold water 
chiller and heat pump unit. In addition it integrates water source and air source heat pump units all together. Considering the whole system comprehensively, under the same cooling capacity and condition, the Evaporative Condenser Chiller compressor consumes 20% less power than the water cooled chiller and 40% lower than the air cooled chiller. The cooling capacity ranges from 400kw to 1100kw, the outlet chilled water temperature ranges from 5 to 20 °C, the heating capacity ranges from 350kw to 950kw, and the outlet hot water temperature ranges from 45°C to 50°C. Suitable for areas where water is limited.

Advantage and feature

A. Low system operating costs

The dual air water source heat pump ompressor input power is at least 10% less than other cooling tower/condenser systems, and 30% less power than air-cooled condenser systems. 

B. High efficiency shell and tube heat exchanger
The dual source geothermal heat pump adopts the self-developed and self-produced high-efficiency shell-and-tube heat exchanger, IPLV reached 10.7, partial load value exceeds 13.

C. Save space and water
The dual source heat pump unit saves the valuable space, beside smaller pumps and pipelines can be installed compare to cooling tower/condenser system. Dual source heat pump system require only about 50% of the upwind area. Moreover, it costs less water consumption (3~5% of water-cooled condenser), and the air flow is small.

D. High efficiency fin evaporator
The dual-source heat pump unit adopts outdoor air-cooled fin-type evaporator, which use air as the heat source during winter, the investment cost and the civil construction investment cost is reduced. Multi-purpose, cooling in summer, heating during winter.

E. Heat recovery (optional)
H.Stars (Guangzhou) Refrigerating Equipment Group Ltd. is the first manufacturer in China to use condensing heat recovery technology. Air source heat pump uses a heat recovery device to recover the waste heat generated during the refrigeration process, which provides customers with chilled water and supply large amount of free hot water.

Dual source heat pump dedicated compressor
The dedicated compressor of water source heat pump has a medium pressure valve, whose pressure is close to the intermediate of the two stage compression, for the economizer. This economizer connection design can achieve no compressed return loss, so as to ensure the compressor can keep running in optimal condition through the whole loading phase. Built-in economizer with specific flow path provides reliable protection to the compressor. According to the characteristics of the user's project, different compression ratios are designed to prevent over-compression or under-compression, as a result the compressor can operate at the optimum efficiency way. During the heat pump condition, the compression ratio is relatively high, as well as the power consumption. In this case, the economizer can reduce the power consumption of the compressor thus achieves a larger energy efficiency.
