Described geothermal heat exchanger by pipe laying flatly and vertically pipe laying form, the ground pipe laying is generally made by PE, PB or PP-R material, and about diameter DN25-50mm, pipe laying is U type pipe or sleeve pipe form vertically, general buried depth 20-100m decides on local shallow-layer geological condition and execution conditions; The horizontal coiled pipe floor space is bigger, buried depth 0.8-1.2 rice.
Described condenser and evaporimeter are the coaxial sleeve tube heat exchanger or pull the formula heat exchanger.
Described water tank is provided with heat-insulation layer, and casing is a stainless steel.
Described water tank is divided into open-type and pressure-bearing type, and the open-type water tank is provided with fluid level control device, and bearing type water tank is provided with pressure protective device.
Adopt the earth source heat pump water heater, owing to make thermal source with the earth, geothermal heat source is stable throughout the year, use not to the utmost.Because adopt heat pump techniques, efficiency higher energy efficiency ratio is about 4-6W/W.Be not subjected to spring, summer, autumn and winter and overcast and rainy wind and snow weather effect,, directly do not utilize underground water, thereby can not pollute underground water resource owing to adopt buried tube side formula to make geothermal heat exchange.Be a kind of safety, environmental protection, energy-conservation, reliable hot-water heating system.
Characteristics of the present utility model are: 1, adopt geothermal using to make the hot-water heating system of thermal source; 2, adopt the vapor compression heat pump technology that hot water is provided; 3, the hot-water heating system of being with water storage to store hot attemperater; 4, three circulations are arranged: the 1) recirculated water of the absorption underground heat that constitutes by water pump-geothermal heat exchanger-evaporimeter circulation.2) the refrigeration working medium circulation of forming by compressor, condenser, throttling arrangement, evaporimeter etc.3) hot water circuit of forming by water pump, water tank, (or water-water heat exchanger) condenser.
The earth source heat pump water heater that designs by the utility model, have weather seasonal effect, efficiency height and the safe and reliable characteristics of not being subjected to, made full use of underground geothermal using resource, domestic hot-water's Teat pump boiler is provided, the round-the-clock life hot water that provides of the four seasons can be provided for family and enterprises and institutions.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 10, geothermal heat exchanger 20, water-loop heat pump hot water unit 21, condenser 22, evaporimeter 23, compressor 30, water tank 41, underground heat water circulating pump 42, hot water supply-water pump 43, throttling arrangement
The specific embodiment
Further specify design feature of the present utility model below in conjunction with accompanying drawing and specific embodiment.
A kind of earth source heat pump water heater as shown in Figure 1 comprises geothermal heat exchanger 10, water-loop heat pump hot water unit 20, water tank 30, underground heat water circulating pump 41 and hot water supply-water pump 42; Described geothermal heat exchanger 10 is embedded in underground, and connects water-loop heat pump hot water unit 20 by underground heat water circulating pump 41; Described water-loop heat pump hot water unit 20 is made up of compressor 23, water-cooled condenser 21, evaporimeter 22 and connection pipe valve; Water-loop heat pump hot water unit 20 connects water tank 30 by hot water supply-water pump 42; Water tank 30 is provided with into water, water outlet, spilling water and drainage interface.
