Efficient heat-pump heat-preservation system

Abstract

The invention discloses an efficient heat-pump heat-preservation system. A dual-layer water tank is arranged through a shell and an inner container, a vacuumizing pipe is arranged and communicated with a vacuum cavity, the vacuum degree of the vacuum cavity is kept under air exhaust by a vacuum pump, the heat insulation aim is achieved, and therefore the heat-preservation performance of a water supply tank is improved; a high-temperature and high-pressure medium is conveyed to a condenser through a heat pump pipe under working of a compressor, water in the inner container is heated, and when the water is heated to the limited temperature, the heat pump pipe stops working, the vacuum pump does intermittent movement, the vacuum degree in the vacuum cavity is kept in the limited range, it isguaranteed that the water temperature in the water supply tank is kept constant accordingly, and heat loss is reduced; meanwhile, compared with an existing mode of packaging a heat insulation layer, through heat insulation of the vacuum cavity, the corrosive phenomenon of the heat insulation layer can be avoided, and therefore the service life of the equipment is prolonged. The efficient heat-pumpheat-preservation system is used for a device of supplying hot water through a heat pump.

Description

technical field [0001] The invention relates to the technical field of heat pump hot water supply, in particular to an efficient heat pump insulation system. Background technique [0002] Heat pump water heaters are commonly used equipment in daily life. The water is heated by the heat collecting device and stored in the water tank. When people use hot water, they can get hot water by opening the outlet pipe of the water tank. The characteristics of the heat pump technology itself are limited. Hot water is delivered to the user end or the water tank has heat loss, and people use hot water intermittently. When the hot water stays in the water tank, it will further increase the heat loss. The existing technology usually adopts the measure of wrapping the insulation layer outside the water tank. In the structure of the traditional insulation system, only one layer of insulation material is wrapped on the water tank. The water absorption rate is relatively high, and the waterpr...

Due to the limitations of the heat pump technology itself, there is heat loss when hot water is delivered to the user end or the water tank, and people use hot water intermittently. When the hot water stays in the water tank, it will further increase the heat loss.

The existing technology usually adopts the measure of wrapping the insulation layer outside the water tank. In th
