Abstract
The utility model discloses an air source heat pump defrost system, which comprises a compressor, a four-way valve, an indoor condenser, a filter, a throttling device and a cycling loop composed of an outdoor evaporator and a gas-liquid separator, wherein the four-way valve is respectively connected with the compressor, the condenser, the evaporator and the gas-liquid separator, a first temperature sensor is arranged on a disk pipe of the evaporator, a second temperature sensor is arranged outdoor, signals collected by the first temperature sensor and the second temperature sensor are inputted to a controller, and the make-and-break of the four-way valve is controlled by the controller. The system has the beneficial effects of simple structure and good defrost effect.
Description
Technical field
The utility model relates to the defrost system of products such as family expenses and commercial air source heat pump.
Background technology
The Teat pump boiler of prior art, generally in being 0～43 ℃ of scope, environment temperature moves, the frosting phenomenon can appear in outdoor evaporimeter when temperature was low, system enters the automatic defrosting state, frost on the outdoor evaporimeter is melted away, thereby guarantee that outdoor evaporimeter and surrounding medium carry out good exchange heat.But when outdoor environment temperature is lower than 0 ℃, Teat pump boiler low-pressure side suction temperature is about-15 ℃, and (defrosting time can not surpass unit total run time 20%) return-air temperature rise is very limited in short time a few minutes, cause delivery temperature also very low, the quantity of heat given up of unit is not enough to the frost on the outdoor evaporimeter is thoroughly melted away, if unit operation overlong time, frosting is more and more thicker on the outdoor evaporimeter of meeting appearance, not only influence unit capacity (unit interval institute's heat production water yield), and make the operational factor substantial deviation design load of system, the compressor pressure ratios value of going beyond the limit of, thus have a strong impact on service life of system.
The utility model content
The purpose of this utility model is to solve the problems of the prior art, provides a kind of defrost effective, the simple air source heat pump defrosting system of technology.
The technical solution of the utility model is: a kind of air source heat pump defrosting system, comprise the closed circuit that compressor, cross valve, indoor condenser, filter, throttling arrangement, outdoor evaporimeter and gas-liquid separator constitute, described cross valve connects compressor, condenser, evaporimeter, gas-liquid separator respectively, the coil pipe of described evaporimeter is provided with first temperature sensor, outdoor second temperature sensor that is provided with, the signal of described first temperature sensor and the second temperature sensor collection inputs to controller, and described controller is controlled the break-make of described cross valve.
The beneficial effects of the utility model are: simple in structure, defrosting effect is good.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model air source heat pump defrosting system, comprise compressor 1, cross valve 2, indoor condenser 3, filter 4, throttling arrangement 5, the closed circuit that outdoor evaporimeter 6 and gas-liquid separator 7 constitute, described cross valve 2 connects compressor 1 respectively, indoor condenser 3, outdoor evaporimeter 6, gas-liquid separator 7, the coil pipe of described evaporimeter 6 is provided with first temperature sensor 61, outdoor second temperature sensor 8 that is provided with, the signal that described first temperature sensor 61 and second temperature sensor 8 are gathered inputs to controller 9, the break-make of the described cross valve 2 of described controller 9 controls, described evaporimeter 6 is provided with blower fan 62.
System is in heating process, the temperature parameter that records by outdoor second temperature sensor, parameter signal is sent to controller, controller is according to outdoor surface heat temperature and the outdoor environment temperature sequencing ground control system of changing that detects, make the cross valve energising, commutation, the closed circuit inverted running, hot gas flows to evaporimeter and carries out the defrost program, the utility model net for air-source heat pump units has realized defrosting automatically, guarantee is heating operation and defrosting effectively continuously under the low-temperature heating state, improves effective heating capacity.
