Abstract

In this paper, based on the comparison of traditional water temperature raising technology, a solar assisted seawater source heat pump system for controlling water temperature is proposed by combining solar thermal utilization technology and seawater source heat pump technology. The results show that this system can effectively improve the temperature of aquaculture water in winter. And the waste heat recovery efficiency in heat recovery subsystem can reach 78%, which accounts for the most to the increase of seawater temperature with the value of 53%. Followed by the seawater source heat pump subsystem, which accounts for 43%. The solar assisted heating system contributes the least, which is 4%. In addition, the energy saving benefits of this system is significant, which can save the operating costs of 53%, 77%, 80%, 90% and 65%, respectively, when compared with coal-fired boilers, gas boilers, oil-fired boilers, electric boilers and air source heat pumps.
