Problems solved by technology

When the unit is used for cooling or heating, the unit is idle in non-heating and air-conditioning seasons, resulting in a waste of investment. When the unit is used for seawater desalination, the water vapor from the condenser is cooled in the evaporator to produce fresh water. Due to the large temperature difference between the water vapor and the refrigerant in the evaporator, the available energy efficiency is low, resulting in a large loss of available energy
In addition, in order to meet the hot water demand for crafts and households, a water heater must be configured separately, which not only requires increased investment, but also takes up more building space

Abstract

The invention discloses a novel four-purpose system capable of cooling, heating and providing hot water and fresh water by using a heat pump of seawater. The novel four-purpose system is characterized in that the system comprises a heat pump system, a fresh water preparation system and a hot water preparation system, wherein the heat pump system includes a compressor (1), a heating condenser (3), a first throttle valve (4), a refrigerating evaporator (5), a gas-liquid separator (7), a liquid reservoir (8), a refrigerant loop solenoid and a water side loop solenoid. The fresh water preparation system comprises a coil condenser (2), a first air channel (18), an inlet air pre-heating heat exchanger (9), a spraying room (10), a water baffle (16), an evaporator (6) for desalting, a second throttle valve (50), and a solenoid (19). The hot water preparation system includes a heat exchanger (11) for preparing hot water, a first air channel (15) and a solenoid (20). The system has the advantages of compact structure, multiple purposes, high-efficiency utilization of waste heat, lowered cost and reduced space.

Description

Technical field: [0001] The patent of the present invention relates to a new seawater heat pump cooling, heating, hot water and fresh water quadruple supply system, in particular to a four-way system that adopts seawater heat pump technology for cooling in summer, heating in winter, providing hot water throughout the year and desalinating seawater to obtain fresh water. A combined power supply system belongs to the technical field of energy and refrigeration and air conditioning. Background technique: [0002] At present, the seawater heat pump unit system is mainly used for refrigeration and heating or seawater desalination treatment, and one unit can only complete one or two of these functions. When the unit is used for cooling or heating, the unit is idle in non-heating and air-conditioning seasons, resulting in a waste of investment. When the unit is used for seawater desalination, the water vapor from the condenser is cooled in the evaporator to produce fresh water. Du...
