Thermal transmission type compressor-free solar heat pump water heater

Abstract

The invention relates to the technical field of water heater manufacturing, in particular to a thermal transmission type compressor-free solar heat pump water heater. The thermal transmission type compressor-free solar heat pump water heater comprises a solar absorber plate and a heat preservation water tank; a plurality of liquid heat exchangers are installed on the back face of the solar absorber plate; and the upper portion of the heat preservation water tank is connected with the upper ends of copper pipes of the liquid heat exchangers through a hot water guiding pipe, and the lower portion of the heat preservation water tank is connected with the lower ends of the copper pipes of the liquid heat exchangers through a cold water guiding pipe. Each liquid heat exchanger comprises a heat preservation cover, electronic heat pumps and the copper pipes; the electronic heat pumps are connected with a power controller through control circuits; the heat absorbing faces of the electronic heat pumps are connected with the back face of the solar absorber plate, copper plates are installed on the heat release faces of the electronic heat pumps, and the copper pipes are installed on the copper plates; and the heat preservation covers cover the copper plates, the electronic heat pumps and the copper pipes on the back face of the solar absorber plate. The thermal transmission type compressor-free solar heat pump water heater is high in thermal energy utilization ratio, large in water yield, good in water heating, convenient to install and use and low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of water heater manufacturing, in particular to a heat transfer type compressorless solar heat pump water heater. Background technique [0002] With the increasing shortage of traditional energy such as coal and oil in the world, the shortage of energy supply has become a bottleneck problem restricting a country's economic development. The development and application of clean energy such as solar energy, wind energy, and nuclear energy has become a strategic emerging industry in China's contemporary and future. As an inexhaustible clean energy source, solar energy is being widely used by human beings. Solar water heaters are becoming one of the household appliances that enter ordinary people's homes. Product popularization is in a stage of steady growth. Solar water heater is a device that uses solar energy as energy to heat hot water, that is, a device that uses the energy of the sun to heat water from low...

Problems solved by technology

Solar water heater collector vacuum tube (flat plate collector), water storage tank and compressor are separated, bulky, inconvenient to install, low energy efficiency, the same is true for air energy water heaters, it is difficult to meet the needs of high-rise residents in the south to install solar water heaters

[0005] In order to facilitate installation and use, people have invented flat (vacuum tube) solar water heaters; however, the current flat (vacuum tube) solar water heaters have the following disadvantages: 1. The hot water produced by solar energy cannot be fully utilized, because its working principle is to control the water pump through temperature difference Start to make the water circulate through the heat collector to obtain hot water. After the hot water flows to the water tank, it pushes the cold water in the water tank to flow back to the heat collector. When the water temperature on both sides is balanced, the water pump stops working, which causes part of the water to return It is left in the heat collector, causing unnecessary waste of heat energy; 2. The existing flat plate (vacuum tube) heat collector is too bulky, requires high technology for installation, and high material cost; 3. Due to the limitation of sunlight, the production of hot water constrained by the weather

4. The pipeline connection between the flat solar water heater and the heat preservation water tank is complicated and inconvenient to install

There is no report on the solar heat pump water heater with or without a compressor in the open literature
