Pipeline heat accumulation type instant-heating high-temperature water source heat pump set water heating system

Abstract

The invention discloses a pipeline heat accumulation type instant-heating high-temperature water source heat pump set water heating system. The system comprises a plurality of heat exchangers, a primary side heating module and a secondary side heating module, wherein the heat exchangers are connected in parallel, and each heat exchanger comprises a primary side and a secondary side which are isolated from each other and can exchange heat; the primary side heating module is communicated with the primary side of each heat exchanger respectively; and the secondary side heating module is communicated with the secondary side of each heat exchanger respectively. The primary sides are not in direct contact with tap water, scaling is avoided, and operation is more stable and efficient; tap water is directly supplied to the tail end after heat exchange, the system is simple and reliable, investment is saved, and the problem that cold water and hot water are different in source is thoroughly solved; pipeline heat storage is adopted, so that the purchasing cost is reduced, the working efficiency of a heat pump is improved, and the operation cost is greatly reduced; and a high-temperature water source heat pump can refrigerate and heat at the same time, is high in comprehensive energy efficiency, and is suitable for scenes with long cooling time and hot water requirements.

Description

technical field [0001] The invention relates to the technical field of heat pump heating water, in particular to a pipe heat storage type instant high-temperature water source heat pump unit heating water system. Background technique [0002] Heat pump heating technology is often used in hotels, hospitals, office buildings, factories and other places. The heat pump heating technology used in the prior art all uses open stainless steel water tanks to store hot water, and then sends it to various places through constant pressure frequency conversion feed water pumps. At the end, it can basically meet the multi-terminal hot water demand in hotels, hospitals, office buildings, factories and other places. However, the open stainless steel water tank and constant pressure frequency conversion water supply system occupy a large area, high cost and large investment, inconvenient transportation, high operating noise, and the heat pump is directly in contact with tap water, causing se...

Problems solved by technology

However, the open stainless steel water tank and constant pressure frequency conversion water supply system occupy a large area, high cost and large investment, inconvenient transportation, high operating noise, and the heat pump is directly in contact with tap water, causing serious scaling; due to the hot water constant pressure frequency conversion water supply system and tap water The constant pressure frequency conversion water supply system has different sources, which often leads to unstable and unbalanced cold and hot water pressure at the end, and the phenomenon of hot and cold when the water is used at the end; and, since the open stainless steel water tank is located at the water inlet of the air source heat pump, it is constant When the temperature of the open stainless steel water tank (for example, 55°C), the inlet water temperature of the air source heat pump is actually the temperature of the open stainless steel water tank, the heating coefficient is low, and the operating cost is increased

[0003] In addition, heat recovery units are also used in the prior art, the main function of which is refrigeration, and heat recovery is an auxiliary function. Generally, it only operates during the cooling season (May-October each year), and the temperature of hot water produced by heat recovery generally does not exceed 55°C. , when there is no need to make hot water, the heat recovery unit still needs to keep running, which greatly increases the operating cost
