Temperature Water

In the area of using renewable energy, promoting the efficiency of seawater source heat pump plays an important part. Several nontraditional technologies are can be used in the new seawater source heat pump system. As for the intake system, infiltration intake technology is introduced, which can increase the supply temperature of sea water and thus raise the efficiency of the system. And as for the terminals, a new-style PVC low temperature water flowing radiant heating (LTWFRH) system is used to match the temperature characteristics of seawater source. After the optimization of the whole system, the seawater source heat pump can be more efficiency and thus saving more energy, considering the energy conservation effect of seawater source heat pump itself.

In a time of permanent care for environmental protection, energy consumption and conservation of resources, heat pumps are becoming increasingly important as a technology for reducing greenhouse gas emissions while preservation thermal comfort in build environment. This paper presents the experimental results of air-source heat pump in different real operating conditions, as follows: for space heating by low-temperature underfloor heating when the supply water temperature was set at 38°C, or for domestic hot water heating in the storage tank volume of 180 liters at a temperature of 46°C. In the low-temperature underfloor heating mode, the efficiency of the air-source heat pump could be increased if the maximum temperature at the end of the compression process and the condensing temperature were reduced in the initial phase of the heat pump operation. In the domestic hot water heating mode, the efficiency of the air-source heat pump could be increased if the maximum condensation temperature in the final phase of the heat pump operation was limited.
