Abstract
An underground water source flooded heat pump set able to switch between refrigerating and heating by controlling circulation of working medium is composed of compressor, oil separator, condensing evaporator, one-way valve, electronic expansion valve, liquie scope, dry filter, level controller, and evaporating condenser. Its advantages are high automation level and low cost.
Description
Technical field: the invention belongs to the full liquid source pump of a kind of underground water source, particularly a kind of heat energy of underground water source that utilizes is by controlling the full liquid source pump that duplex matter system is realized refrigeration or heated the industrial and mineral change working.
Background technology: the existing full liquid source pump of underground water source of utilizing, the refrigeration of this unit, the conversion of heating condition are to rely on the control to 8 stop valves of water circuit system to realize.Concrete scheme is: with reference to figure 2, during refrigeration, valve A closes, and valve B leaves, and water pump enters pipeline 1 with underground well water through water treatment facilities and check valve, again through valve B
1Enter condenser, the water route part is drawn the working medium heat of condensation and is entered pipeline 4 in condenser, through valve B
3The conversion and get back in the back water well, recirculated water then by water circulating pump with system water through valve B
2Enter evaporimeter, in evaporimeter, be condensed into cold water and enter pipeline 3, through valve B
4Enter water system and send into air-conditioned room.When heating, valve A leaves, and valve B closes, and water pump enters pipeline 1 with underground well water through water treatment facilities and check valve, again through valve A
1Enter evaporimeter, in evaporimeter, entered pipeline 3 after the heat absorption, through valve A
3Change and get back in the back water well, system water then enters pipeline 2 by water circulating pump, through valve A
2Enter condenser, in condenser, be heated to form hot water and enter pipeline 4, through valve A
4Enter water system and send into air-conditioned room heating.When realizing change working, need operate stop valve, waste of manpower manually like this.
Summary of the invention: technical problem to be solved by this invention be exactly background technology exist when realizing change working, need operate stop valve, waste of manpower manually.Addressing this problem the technical scheme that is adopted is: the full liquid source pump of a kind of underground water source, this unit is formed by connecting by pipeline by compressor, oil eliminator, condenser/evaporator, check valve, electric expansion valve, liquid visor, device for drying and filtering, fluid level controller, evaporative condenser, it is characterized in that cross valve is connected with compressor, evaporative condenser, oil eliminator, condenser/evaporator respectively by pipeline.Wherein, no matter heat or during cooling condition, working medium is all in the shell side circulation, and chilled water or cooling water all circulate at tube side; Condenser under cooling condition is converted to evaporimeter under heating condition, the evaporimeter during cooling condition then is converted to condenser when heating condition.The beneficial effect that the present invention and background technology comparison are had is: owing to adopt technique scheme, and first, automatic conversion with heating condition can realize freezing.Promptly by the electromagnetic switch of four-way change-over valve, the flow direction that changes the cross valve path realizes conversion, the inconvenience of having avoided the Artificial Control stop valve to be brought, and simplified unit.The second, when the strong water of corrosivity such as using seawater is done thermal source, only need the heat-transfer pipe in the condenser/evaporator is adopted anti-corrosion pipe, and evaporative condenser still adopts common heat-transfer pipe to get final product, and omitted simultaneously existing seawater thermal source unit heat exchanger plates in the middle of the titanium that must use, thereby reduced the unit cost; And because no heat transfer temperature difference so improved unit refrigeration or heating capacity, has improved Energy Efficiency Ratio simultaneously.
Description of drawings: Fig. 1 is a unit schematic diagram of the present invention; Fig. 2 is a background technology principle key diagram.
The specific embodiment: with reference to figure 1, the full liquid source pump of a kind of underground water source, this unit is formed by connecting by pipeline by compressor 1, oil eliminator 2, condenser/evaporator 4, check valve 5, electric expansion valve 6, liquid visor 7, device for drying and filtering 8, fluid level controller 10, evaporative condenser 11, and cross valve 3 is connected with compressor 1, evaporative condenser 11, oil eliminator 2, condenser/evaporator 4 respectively by pipeline.No matter heat or during cooling condition, working medium is all in the shell side circulation, and chilled water or cooling water all circulate at tube side.Like this, the condenser under cooling condition is converted to evaporimeter under heating condition, and the evaporimeter during cooling condition then is converted to condenser when heating condition.
