Abstract
Aiming at the defects existing in constant-temperature preserving equipment at present, the utility model provides simple constant-temperature preserving equipment which carries out temperature regulation for a preserving region by utilizing reverse Carnot cycle through the phase change of a refrigerant and comprises a compressor, a gas-liquid separator, an air-side heat exchanger, a four-way valve, a temperature-regulating heat exchanger, a bidirectional expansion valve, a temperature sensor, a control part and a preserving chamber. The mode of temperature change is controlled through the four-way valve, and the purpose of regulating the inside temperature of the preserving chamber is realized by continuously controlling the on-off of the compressor and adjusting the four-way valve as required.
Description
Technical field
The utility model relates to a kind of constant temperature preservation equipment, specifically, relates to the contrary Carnot cycle of a kind of utilization and by the cold-producing medium phase-state change thermoregulator simple and easy constant temperature preservation equipment is carried out in the preservation zone.
Prior art
The constant temperature preservation is used more and more widely now, and all can see it at aspects such as medicine, food, aquatic products, transportations and use, but the present general more complicated of constant temperature preservation equipment, appearance and size is bigger, causes price higher.Therefore, for the place that partly need carry out the constant temperature preservation, be limited to space or economic cause and selected relatively cheap common deepfreeze for use, its temperature fluctuation is obvious, can't make by the preservation article and be in optimized state of temperature, and its temperature control point is single, can't realize the requirement of many serviceability temperatures.
The utility model content
The utility model provides the contrary Carnot cycle of a kind of utilization by the cold-producing medium phase-state change thermoregulator simple and easy constant temperature preservation equipment to be carried out in the preservation zone at the deficiency that present constant temperature preservation equipment exists.
The utility model is achieved in that constant temperature holding room equipment mainly is made up of compressor, gas-liquid separator, air-side heat exchanger, cross valve, temperature adjustment heat exchanger, two-way expansion valve, temperature sensor, control section and holding room.Compressor connects cross valve one interface, and its excess-three of cross valve interface connects air-side heat exchanger, temperature adjustment heat exchanger and gas-liquid separator respectively, and gas-liquid separator connects compressor, is connected with two-way expansion valve between air-side heat exchanger and the temperature adjustment heat exchanger.The compressor that drives timeliness holding room inside by electric energy compresses the working medium in the circulation line, the working medium temperature adjustment heat exchanger in holding room and air-side heat exchanger is respectively carried out heat exchange, by cross valve control variations in temperature mode, constantly control the start and stop of compressor as required and adjust the purpose that cross valve realizes regulating the preservation indoor temperature.
During operation, at first set the temperature of handling needs by control system according to the memory requirement of preservation article, behind the compressor start, compare with the temperature of presetting by detecting the holding room internal temperature, controlling compressor thus freezes or heating operation to holding room, make indoor temperature maintenance at the preset temperature curve, and in running time subsequently, regularly running temperature and preset temperature are compared, control the start and stop of compressor and the state of cross valve thus, make the temperature of actual motion close with the preset temperature curve.Thus, the utility model has effectively overcome present constant temperature preservation device structure complexity, can not realize miniaturization, and the more high shortcoming of price utilizes it good economy performance to be installed simply in the constant temperature preservation under the little spatiality.
Description of drawings
Figure (1) is a structure principle chart of the present utility model.
The specific embodiment
During operation, at first set the curve of the temperature of needs by control system according to the memory requirement of preservation article, after compressor (7) starts, temperature sensor (2) detects holding room (1) internal temperature and it is transferred to control system (9), by control system (9) temperature value of actual temperature with the corresponding time point of presetting of temperature curve compared, if be higher than preset temperature value, then control unit and carry out refrigerating operaton, promptly controlling cross valve (6) links to each other compressor (7) gas outlet with air-side heat exchanger (5), gas-liquid separator (8) links to each other with temperature adjustment heat exchanger (3), at this moment, cycle fluid evaporates in temperature adjustment heat exchanger (3), and the heat of drawing in the holding room (1) reduces its temperature.Temperature sensor (2) in Fixed Time Interval detects holding room (1) temperature and it is transferred to control system (9), when indoor actual temperature is lower than the temperature value of the corresponding time point of default temperature curve, control system (9) control cross valve (6) links to each other gas-liquid separator (8) with air-side heat exchanger (5), the gas outlet links to each other with temperature adjustment heat exchanger (3), at this moment, cycle fluid condensation heat release in temperature adjustment heat exchanger (3) raises the temperature in the holding room (1).Every through the set time section, the temperature signal that control system (9) meeting temperature sensor (2) transmits, the contrast preset temperature value, the control unit freezes or the heating mode operation, interior temperature of holding room (1) and preset temperature curve are matched, guarantee that preservation Wen Pin is in the steady temperature of appointment.
Claims (2)
1. simple and easy constant temperature preservation equipment, mainly be made up of compressor, gas-liquid separator, air-side heat exchanger, cross valve, temperature adjustment heat exchanger, two-way expansion valve, temperature sensor, control section and holding room, it is characterized in that: temperature sensor is in holding room.
2. a kind of simple and easy constant temperature preservation equipment according to claim 1 is characterized in that: by the adjustment of cross valve, the temperature adjustment heat exchanger in the cooling pattern as evaporimeter, in heating mode as condenser.
