Abstract

A synergistic antifreeze water source heat pump device, which belongs to the field of heat exchange technology, is composed of a heat pump unit, a water inlet pipe, a drain pipe and a water pump, a check valve is installed on the water inlet pipe between the water pump and the heat pump unit, and a The upper water tank is equipped with an upper water pipe and a lower water pipe. The other ends of the upper water pipe and the lower water pipe are connected to the water inlet pipe between the one-way valve and the heat pump unit. The lower water pipe is equipped with an unconventional solenoid valve. The underground hot water first fills the high-level water tank, and then enters the heat pump unit through the water inlet pipe for heat exchange. When the system is powered off, the unconventional solenoid valve opens, and the hot water in the high-level water tank rushes into the heat pump unit to discharge the cold water in the heat pump unit. . The invention improves the efficiency of the water source heat pump unit and prevents the water source heat pump unit from being damaged by freezing.

Description

Technical field: [0001] The invention belongs to the technical field of heat exchange, and relates to a water source heat pump device. Background technique: [0002] Water source heat pump technology has been widely used in Europe and the United States for its advantages of saving fossil energy and environmental protection. It is composed of heat pump unit, water inlet pipe, drain pipe, water pump and check valve. The water pump sends underground hot water to the heat pump unit through the water inlet pipe. Inside, heat exchange is performed to obtain thermal energy, after which cold water is returned to the ground from the drain pipe. In recent years, water source heat pump technology has also developed rapidly in our country, but many problems have also appeared in the process of use. The northern part of my country is the area with the most heating demand in winter. In most areas, the outlet water temperature of the water source heat pump pumping well is 10 ℃, and the ou...
